In 2017, a video of “Chinese bulletproof plate scares Americans” was wildly spread on the Internet.An American spent $100 to buy China's level IV bulletproof insert plate, and successively experienced the close range direct fire test of 7.62mm power bullet and moxinagan rifle bullet.The result surprised the American: the bulletproof plate withstood all the attacks of the gun!How did Chinese bulletproof vests counter attack?American soldiers, why do they even buy it out of their own pocket?     High quality and low price In retrospect, the protection of individual soldiers runs through the whole war history of mankind.In the age of cold weapons, there were animal skins and metal armor; In modern war, the killing power of weapons has increased sharply, and governments of various countries have invested in the research of bulletproof vests. After nearly one hundred years of development, the commercial bulletproof clothing has formed two main streams of hard materials and soft materials.The hard material uses the high hardness of the insert plate itself to resist the physical impact of bullets and protect the human body.Soft materials are drawn into filaments with high-strength and good tensile chemical fibers or polymers, and then woven into cloth, which is superimposed layer by layer to absorb bullet kinetic energy.The individual protective equipment of the US Army is the world leader, but their counterfeiting is often prohibitive. The quality of bulletproof products made in China is not weaker than those made in the United States, but the price is often only half of theirs.The bulletproof products produced by SBA mainly take silicon carbide and boron carbide ceramic materials as the core, and the new generation of bulletproof insert plate also has super resistance.The 15 mm thick insert plate made of silicon carbide, boron carbide ceramics and fiber composite materials was fired with 5.8 mm (Chinese standard) steel core bullet for many times. Not only the depression depth at the shot place was not more than 25 mm, but also only microcracks appeared in the continuous shooting in the same area, which did not affect the normal use of other areas.In 2003, relevant British departments purchased more than 600 bulletproof vests due to war needs. A British soldier recalled after the war that he was surrounded by the Taliban and miraculously survived after the other party fired 12 shots in a row.The bulletproof vest worn by the British soldier at that time was made in China.Even if China's bulletproof vests are strong, the key is very cheap.The domestic ceramic bulletproof clothing at the price of US $200 can meet the comprehensive needs of customers to defend against “large caliber, strong power and close range direct fire”, while the bulletproof clothing produced by Western military enterprises can only be done at the cheapest price of US $500 if they meet the above needs.If it's you, which one do you buy?With good quality and low price, it naturally sells well all over the world.China's bulletproof clothing sales share accounts for 70% of the world. Military forces of various countries have said they want to buy Chinese bulletproof vests.It is said that many American soldiers buy Chinese bulletproof vests out of their own pocket without using the bulletproof vests distributed by the United States.   The road of counter attack — Bulletproof Product — Made In China Like many other industries, China's bulletproof clothing manufacturing road is neither the earliest nor the most smooth.China's independent research and development of bulletproof vests started very late.It was not until the late 1950s that the relevant logistics R & D departments of the people's Liberation Army began to project the R & D of domestic bulletproof clothing, and its main purpose was only to provide basic protection for military security and logistics personnel.The Vietnam War launched by the United States alerted our military.Under the US air raid, the high-speed steel balls and ammunition fragments of air explosive submunitions pose a great threat to China's anti-aircraft artillery, transportation and engineering troops sent to assist North Vietnam. It is urgent to strengthen individual protection.From the late 1960s to the early 1970s, the Logistics Department of the PLA successfully developed and put into production two kinds of bulletproof vests, which was the first large-scale production of bulletproof vests of the PLA.In the United States, in the 1970s, DuPont has developed a synthetic fiber called “Kevlar”.The emergence of “Kevlar” is a historic change in bulletproof clothing materials. The shrapnel energy absorbed by this material is 1.6 times that of nylon and 2 times that of steel. Most importantly, Kevlar is particularly lightweight.After the reform and opening up, the independent research and development of China's national defense vest has slowed down.In the 1980s and 1990s, a small amount of domestic bulletproof vests were mainly provided to peacekeeping forces, public security units, anti-terrorism special warfare and other specific units, and were not put into mass production.After entering the 21st century, the military and the Ministry of public security began to produce bulletproof vests on a real scale.The Quartermaster Equipment Research Institute of the General Logistics Department has developed 2004 series bulletproof vests. Subsequently, the 2006 special forces bulletproof vest was also developed.06 bulletproof vest adds webbing on the front and reduces webbing on the back, which makes the design more reasonable. The research and development of the military has advanced by leaps and bounds, and the research and development of the police has also been carried out step by step.On September 3, 2015, “15 type Armed Police General / special combat bulletproof vest” was officially unveiled at the military parade marking the 70th anniversary of the victory of the war of resistance against Japan.The protective performance of type 15 armed police special combat bulletproof vest has been improved to the first square array in the world, and the waist protection components have been added to cover the waist protection blind area. Moreover, the total weight of the bulletproof vest is only about 5.1kg, and only about 2.8kg without protective components.In addition, the quick disassembly function is added in the design, which is very useful in practice.The standard of Chinese bulletproof vests has been excellent from the beginning. The standard of domestic bulletproof vests is stricter than that of the United States.The depression degree index left on the backing mastic after the bullet impact of bulletproof clothing products is the key index. It can not only control the non penetrating injury to the human body caused by shooting, but also avoid the compressive injury to the subcutaneous tissue, especially the internal organs.According to China's ga141-2010 standard, the depression must be ≤ 25mm, while the American NIJ standard requires ≤ 44mm.This means that China's bulletproof vest must be able to absorb more kinetic energy than the US National Defense vest before it can be considered qualified.The reason why we dare to set a high standard is that made in China has full confidence.The first is the breakthrough of key materials.China is the fourth country to master the production and application technology of this kind of fiber only from the production of soft material UHMWPE fiber and weft free cloth.After 2000, the number of domestic patent applications for bulletproof vests soared.From the perspective of patent types, they are mainly concentrated in the fields of armor (f41h), layered products (b32b), fiber (d01f), protective clothing (a41d), composition of high molecular compounds (c08l), fabric treatment (d03d and d06m), inorganic and high molecular organic materials as ingredients (c08k), accounting for nearly 80% of the total application volume, respectively reflecting the characteristics of our national defense bulletproof clothing in bulletproof clothing, bulletproof layer structure, bulletproof materials New breakthroughs in bulletproof layer fabric treatment, composite bulletproof materials and other aspects.     Patents provide the greatest help for the development of China's billing products! After 2000, the number of domestic patent applications for bulletproof vests soared.From the perspective of patent types, they are mainly concentrated in the fields of armor (f41h), layered products (b32b), fiber (d01f), protective clothing (a41d), composition of high molecular compounds (c08l), fabric treatment (d03d and d06m), inorganic and high molecular organic materials as ingredients (c08k), accounting for nearly 80% of the total application volume, respectively reflecting the characteristics of our national defense bulletproof clothing in bulletproof clothing, bulletproof layer structure, bulletproof materials New breakthroughs in bulletproof layer fabric treatment, composite bulletproof materials and other aspects. The second is the perfection of the industrial chain.Many people may not know that among nearly 200 countries and regions around the world, only three manufacturing countries can independently complete the whole process from the R & D of bulletproof clothing raw materials to the completion of production, namely the United States, China and the Netherlands.With complete industrial chain and coordinated development of upstream and downstream, the price advantage is naturally prominent.The strength of UHMWPE fiber developed in China is close to that of the Netherlands, and the price is much lower than that of similar products in the Netherlands, the United States and Japan.Therefore, the manufacturing cost of bulletproof vests produced in China can be reduced and has obvious cost advantages in the market.     Great significance in Bulletproof industary At the beginning of the founding of new China, China's bulletproof clothing manufacturing technology was backward, which was not worth talking about in the world.The United States easily monopolized the international market of bulletproof vests with the hot “Kevlar” technology at that time. Bulletproof vests from other countries are either not available or affordable.Now, our bulletproof vests in China can be manufactured independently and at low prices. They are not only self-sufficient, but also export to earn foreign exchange.   China's military strength has taken a big step, which has also broken the monopoly of the United States.The high-quality and cheap Chinese bulletproof vests have greatly reduced the procurement cost of our military equipment.At a time when global military spending is rising, China's bulletproof vests reduce the burden on China's defense budget at a low price.The per capita military expenditure of the United States was $2224 in 2019, while that of China was less than $200 in the same year.The price of military products made in China is low not only for bulletproof vests, but also for other products, so the cost of national defense has been reduced.In addition to self-sufficiency, China's export of bulletproof vests has also driven China's economic development.Manufacturing bulletproof clothing requires chemical enterprises or iron and steel enterprises to produce raw materials, as well as textile enterprises to make fiber fabrics. The garment factory finally completes the finished bulletproof clothing.The export of bulletproof clothing drives the whole production chain and plays a strong role in driving the economy. Many enterprises in Jiangsu and Zhejiang earn foreign exchange by exporting bulletproof vests.The most direct function of bulletproof clothing is to strengthen the defense of individual soldiers.War tests the comprehensive ability of attack and defense. Bulletproof vests undoubtedly improve the defense of individual soldiers.

Overview NIJ 0101.06 IIIA rated bulletproof plates are designed to provide maximum protection against firearms according to the National Institute of Justice (NIJ). NIJ IIIA bulletproof plates are typically made of hard armor materials such as Ceramic, Steel, Polyethylene, Hybrid, and other composite materials or soft armor material such as Polyethylene, Aramid(Kevlar, Twaron) or others. Specific designs of hard armor plates should meet the following performance criteria for NIJ IIIA ballistic protection:• Resistant to 9mm rounds fired at a velocity of less than 1,095 ft/s (block at least 1 hit from 9mm rounds) • Resistant to .357 Magnum rounds fired at a velocity of less than 1,430 ft/s (block at least 1 hit from .357 Magnum rounds) • Resistant to .44 Magnum rounds fired at a velocity of less than 1,499 ft/s (block at least 1 hit from .44 Magnum rounds) • Resistant to specialty rounds like AP rounds, hollow-point rounds, and other similar rounds (block at least 1 hit from appropriately-designed specialrounds)   1.

The plate must also meet the National Institute of Justice’s NIJ 0101.06 testing criteria for level IIIA armor, and should provide at least six years of high-performance ballistic protection. Moreover, the plate must be compatible with operational gear and other protective gear, and must be constructed and tested under quality assurance controls with extensive quality testing prior to delivery to customers.

Level IV plates are currently the highest-rated armor recognized by the NIJ. According to the NIJ ratings, level 4 plates are only required to defeat one round of armor-piercing .30-06 Black Tip ammunition. However, during the NIJ .06 Certification testing, an entire lot of level 4 armor must also be subjected to a drop test, water submersion, temperature cycle chambers, as well as other important tests to determine the integrity of the ballistic materials. All of those tests are completed before the ballistic test is done.   If you’re considering buying level 4 body armor, we’re here to answer some of the most frequently asked questions regarding one of the most popular body armor levels. But first let’s go over what exactly level iv armor is.   CERAMIC BODY ARMOR Level IV body armor is made from a hard surfaced strike face and some sort of lightweight backer. But the ceramic strike face is an integral part of breaking apart any armor piercing round. On the surface, ceramic is a hard, heat-resistant material that is also averse to corrosion. For body armor, you typcially use one of three ceramic materials for a Level 4 strike face – alumina-oxide, silicon carbide or boron carbide. Alumina is the heaviest ceramic used in body armor, but it’s also the least expensive. RMA utilizes an alumina-oxide ceramic in our model 1155 Level 4 body armor plates and 6×6 side plates. Silicon-carbide ceramic and boron-carbide ceramic are both lighter, but more expensive ceramic strike faces found in level 4 plates. RMA’s model 1192 hard armor plate utilizes a silicon and boron-carbide blend to produce a lightweight body armor plate that weighs just 5.9lbs.  Ceramic alone is not sufficient to defeat a 30.06 armor piercing round. While the ceramic does in fact break apart the ammunition, a polyethylene backer made of ultra-high molecular weight polyethylene (UHMWPE) or e-glass is required to catch the bullet fragments and minimize back-face deformation.  Compared to any type steel body armor, ceramic body armor is better at absorbing and dispersing energy than steel. This means that wearing ceramic armor will result in less broken ribs and other injuries to your bones and internal organs. And because of the ceramic, these plates performs much better versus armor-piercing bullets and high-velocity rounds when compared to steel body armor.  Level 4 body armor has historically been made from steel or ceramic composites—but as technology has changed, so have materials. Today, body armor manufacturers are using all sorts of materials to defeat ballistic threats such ceramic composites, ultra high molecular weight polyethylene (UHMWPE) fabrics, aramids like Twaron and Kevlar, steel, silicon carbide, boron carbide, carbon nanotubes, and more. Because of this broad range of materials and manufacturing methods, some level 4 armor will strictly only defeat one single round of M2AP while others will defeat multiple M2AP strikes.  Level IV body armor can weigh anywhere from as little as 5-pounds or as much as 9-pounds, depending on the materials used and shape of the plate. A declaration of level 4 armor protection under NIJ certification is a good place to start your buying decisions, but pay attention to weight, price, and total number of bullet strikes a plate can protect you from before you buy. Most importantly, ensure you purchase your armor from a reputable source and manufacturer that has a reputation for high quality products. Don’t bet your life on anything less.    WHAT IS LEVEL 4 BODY ARMOR? Though many other formats have been tried, the only tried-and-true reliable format of level 4 body armor is the hard plate. The most common size of level 4 body armor is the 10 x 12 hard plate. The vast majority of adult humans can properly fit a 10 x 12 plate for torso and back coverage, though other formats like SAPI/ESAPI, shapes such as shooter’s or swimmer’s cut, and larger and smaller sizes exist.    WHAT IS A LEVEL IV PLATE? A level IV plate is rated to defeat one round of M2AP ammunition at a minimum before it is fully compromised. A level IV plate is the highest level of ballistic protection rated under the current National Institute of Justice 0101.06 standard. Though commonly called ‘Level 4’, the technical nomenclature to describe armor levels under the NIJ 0101.06 standard is with roman numerals in ascending levels of protection as IIA, II, IIIA, III, and IV.   WHAT WILL LEVEL 4 PLATES STOP? The National Institute of Justice only tests 1 single strike of 7.62 M2AP (30-06 steel) against level 4 plates for NIJ 0101.06 certification. But any level 4 plate that been certified by NIJ should also stop one strike from any round less powerful than M2AP such as 5.56mm, 7.62X39mm, .308 WIN/7.62 NATO, and all handgun rounds like 9X19mm, .40S&W, and .45 ACP.    HOW MANY HITS CAN A CERAMIC PLATE TAKE? While NIJ tests confirm that any certified level 4 plate will stop a single round of M2AP 30-06, some plates can go beyond this single hit certification. Additionally, most level 4 ceramic plates can handle a surprising number of lower-powered rounds like 9mm, 5.56mm, and others that impact with far less force than M2AP. Each of RMA’s ceramic plates are multi-hit capable.

After entering the era of hot weapons, ancient armors used to defend cold weapons such as knives, spears, bows and arrows have gradually been eliminated, but people have not given up on the pursuit of body protection equipment. As a result, body armor appeared as an important personal protective equipment.     The original body armor was made of metal material, but because it weighed more than 40 kilograms, it was very inconvenient to wear and move, and had to be abandoned. In addition, Europe also invented multi-layer silk body armor, cotton or cloth body armor. But the protective effect can be imagined. After the baptism of the two world wars and technological progress, the weight of the new metal body armor was greatly reduced. The manganese steel body armor of the US military weighed only 4 kilograms. In addition, a lighter ceramic body armor was successfully studied. But these two kinds of body armor are very hard. Although the bulletproof effect is good, it affects the body to bend freely, so it is still not universally used.   It was not until the 1970s that a very ideal body armor material-"Kevlar" finally appeared. "Kevlar" is a soft fiber, both soft as cotton and tough as steel. Its strength is 5 times that of steel of the same quality, and its density is only 1/5. The new-style body armor made of this material is not only soft and flexible, but also has strong bullet-proof ability. It is favored by the army and police of many countries. Several instances of local wars in recent years have also proved that the "Kevlar" body armor is indeed the "armor guard" of the soldiers.   With the development of science and technology, after the "Kevlar" material, a new generation of bulletproof materials-ultra-high molecular weight polyethylene (PE) bulletproof material appeared, which has ultra-light and super strong performance, but the density is only "Kevlar Pull" 70%. Due to its ultra-high stability, low temperature resistance, UV resistance, water resistance, and light weight, polyethylene has become an ideal material for making bulletproof equipment. Since the defense level of soft body armor is limited by material performance, it cannot increase defense indefinitely. As a high-density and high-strength bullet-proof material, bullet-proof inserts just make up for the insufficient density of the body armor contents, so the current single-soldier defense combination of body armor + bullet-proof inserts is formed.   According to the current individual protection needs of the security market, China Hengtai Defense will soon launch a series of body armor products, which can produce different levels of body armor according to requirements. The clothes can carry bulletproof panels to provide a higher level of protection. Product Specifications:   Protective effect: it meets the requirements of GA141-2010 "Police bulletproof vest" standard, and can reach the protection effect of level 2~6. At the same time, it meets the bulletproof requirements of GJB4300A-2012 "Military bulletproof vest safety technical performance requirements" standard. Meet the relevant protection level requirements of the US NIJ0101.06 standard. The protective area is ≥0.25 square meters, which can cover the main organs of the human trunk and provide safer protection for the wearer. In addition, the body surface adopts a special environmentally friendly cushioning foamed plastic structure, which can greatly reduce the impact energy when bombed and reduce the damage to the human body;     2. Style and color: 99 police uniform color (customizable); style can be customized, body length and waist circumference can be adjusted by Velcro, which can adapt to 95% of the wearer's figure;   3. The internal structure and material of the bulletproof vest: It is composed of a soft bulletproof layer and a shock absorption layer. The soft bulletproof layer is made of ultra-high molecular weight polyethylene or aramid finished bulletproof cloth, and is composed of multiple layers of bulletproof materials;   4. Product use: body armor can be used all-weather, and the safety of the clothing can be guaranteed under the temperature condition of -20℃ to +55℃. The product can be used in important departments such as public security, police, armed escort, border defense forces, etc. It is an essential personal protective equipment for maintaining stability, dealing with emergencies, and handling emergencies. The body armor jacket can be customized according to needs, and more equipment can be carried at the same time .

With the deterioration and escalation of international terrorist incidents, bulletproof equipment has gradually entered the public's field of vision, and various bulletproof products are dazzling. People usually have to consider many factors when buying these products, and the shelf life is undoubtedly an important factor that people will consider when choosing bulletproof products. So why do bulletproof products have a shelf life, and how long is the shelf life in general? Here is a detailed explanation for this problem. All bullet-proof products, such as bullet-proof vests and bullet proof Plates inserts, are made of one or several materials through a special process. Different materials have different characteristics, and they will age with time. Therefore, all bulletproof products have a shelf life, and different bulletproof products have different shelf life. However, when it comes to the shelf life of bulletproof products, many people may have a certain misunderstanding that they believe that bulletproof products will maintain the normal level of bulletproof during the marked shelf life, which is not the case. In reality, the protection effect of bulletproof products during the warranty period is affected by many factors, such as material, frequency of use, correct maintenance and product size. Let's explain for you separately:   1. Material The material of bulletproof products is an important factor that affects their service life. Just like all organics, the materials used to make bulletproof products will change over time, resulting in a decline in product performance. Therefore, the material of bulletproof equipment is the main factor that affects its shelf life. Currently, there are many materials used to make bulletproof products, such as Kevlar, Aramid, Twaron, PE, steel and ceramics. The shelf life of bulletproof products of different materials will vary. For example, soft body armor is less resistant to humidity and high temperature than hard body armor. Once the soft body armor is soaked, it is not suitable for continued use. The high temperature resistance of PE-component body armor is also weaker than Kevlar.   2. Frequency of use The frequency of use of bulletproof products is also an important factor that affects the service life of bulletproof products. For example, the bulletproof vests that are often worn will definitely decrease their bulletproof performance compared to those that are used once in a while. It is inevitable that there will be a certain amount of wear when wearing, the more serious the wear, the shorter the service life. Especially when used in harsh environments, the impact on the performance of bulletproof equipment will be greater.   3. Maintenance The maintenance method will also have a certain impact on its ballistic performance. Some products have certain requirements for the preservation environment due to the material. For example, the widely used Kevlar bulletproof vests and bulletproof panels need to be kept away from direct sunlight and direct contact with water. If you need to clean them, just wipe them with a damp cloth. If they are in contact with water for a long time, their bulletproof ability will be greatly reduced, thus greatly shortening their service life. In addition, the body armor should be deployed in a flat place as much as possible during daily storage, while the PE body armor needs to be avoided in high temperature environments.   4. Dimensions When choosing a body armor, whether the size is appropriate will also affect the service life of the body armor to a certain extent. If the size of the selected ballistic body armor is too large to fit the body, the user will shake the body armor constantly during exercise. This will adversely affect the life of the body armor; if the size of the body armor is too small and too tight, the body armor will remain stretched for a long time, and its ballistic performance will also decrease. Therefore, if the size of the ballistic body armor is too large or too small, it will cause damage to a certain degree, affecting its service life and effect. It can be seen that the fit of the body armor is very important for maintaining the long-term bulletproof effect.   Manufacturers do not know how buyers will use and maintain these products. Therefore, they usually give a rough time frame by performing some performance and environmental tests on the products, and indicate: "If there is no human damage, it will be valid within the warranty period." . For bulletproof products, the warranty period promised by manufacturers will not be too long. At present, most bulletproof products on the market have a shelf life of 3 to 5 years. Because if the manufacturer guarantees a long shelf life to the buyer, this may increase the cost of insurance and eventually increase the price of the product. Therefore, even if the shelf life of some products is clearly marked on the shelf, it does not mean that these products are past the shelf life. It must have lost its due ballistic capability. Nevertheless, we suggest that it is best not to continue to use bulletproof products beyond the shelf life. Even if you think your bulletproof equipment still has good bulletproof capabilities after the shelf life, it is best not to risk continuing to use it, because life and death is not Child's play.

What is a Half Face Bulletproof Mask and How Does It Provide Maximum Protection A half face bulletproof mask is a piece of personal protective equipment that covers the face and provides protection from ballistic threats. These masks are designed to be worn with helmets and provide additional coverage to the most vulnerable parts of the face, such as the nose, mouth, and cheeks. They are made with materials that are resistant to ballistic threats and are designed to absorb the impact of a bullet, reducing the likelihood of injury.Half face bulletproof masks are made from a variety of materials, including Kevlar, ballistic nylon, and ceramic plates. The most common material used in the construction of these masks is Kevlar, which is a strong and lightweight synthetic fiber. Kevlar is five times stronger than steel and has the ability to absorb and disperse the energy from a bullet impact, reducing the force of the impact and minimizing injury.The design of a half-face bulletproof mask is also critical to its effectiveness. The mask should fit snugly to the wearer's face to ensure maximum protection. It should also be lightweight and comfortable to wear for extended periods of time. Some masks have adjustable straps or padding to improve fit and comfort. Types of Half-Face Bulletproof Masks for Helmets and Their Benefits There are several different types of half face bulletproof masks available on the market today. Each type has its own unique features and benefits, making it important to choose the right mask based on your specific needs and requirements.

When it comes to bulletproof equipment, we may first think of bulletproof vests, bulletproof inserts, bulletproof helmets, bulletproof glass, etc. Few people have heard of bulletproof masks. Indeed, compared to bulletproof helmets, bulletproof masks do not seem to be as widely used in practical applications as other bulletproof equipment, but they also often appear in various military security activities. The main function of bulletproof masks is to avoid or reduce combat. Damage to the wearer’s face from bullets or explosive fragments during the process.Before the emergence of bulletproof masks, people used bulletproof masks to protect their faces. The earliest bulletproof masks were made of metal. Usually only the eye part was hollowed out to facilitate the observation of the external situation. Although this kind of mask can provide the wearer with a certain It has a high degree of protection, but it is conceivable that its weight and limitation of vision also bring a lot of inconvenience to the wearer. With the development of material science and the continuous improvement of people’s requirements for bulletproof equipment, this kind of bulletproof mask has gradually been eliminated and replaced by a new type of bulletproof mask. A bulletproof mask is a protective equipment that can absorb and dissipate the energy of the warhead, prevent penetration and effectively protect the human face, and its transparent appearance does not affect normal observation. Compared with the bulletproof mask, the bulletproof mask has undergone essential changes in appearance and material. From the perspective of appearance, the bulletproof mask is an arc-shaped sheet structure, because it is usually made of transparent materials and will not affect the line of sight. , so there is no need for the eye hollow design, and the protective area is larger; in addition, the use of high-performance materials can greatly reduce the weight of the mask while improving the protective performance. Great convenience. Nevertheless, considering the wearer’s load-bearing problem, usually the highest protection ability of bulletproof masks is to prevent pistol bullets. In addition to this, this ballistic mask needs to be used in conjunction with a helmet. Generally speaking, a helmet that can defend against 7.62mm AK47 bullets weighs about 1.5-2kg, plus the weight of the bulletproof mask, which is a big challenge for the neck of the wearer who needs to wear bulletproof helmets and masks for a long time. . In the case of the soldier, the bulletproof mask will be close to or even touch the butt part of the gun when the soldier is aiming, which may cause a certain degree of interference to the soldier’s shooting. This is also the reason why bulletproof masks are not as widely used in the military field as other bulletproof equipment. Of course, sometimes face protection is also necessary in order to deal with some more special combat scenarios with higher risk levels, and more comprehensive protection is often needed at this time.

Modern bulletproof chest inserts are constructed of several different materials. Now the common and better protective effect is ceramics. Although it is called a ceramic bulletproof plate, not the entire bulletproof plate is composed of ceramics. Usually, a whole piece of bulletproof fiber processed into a hard bulletproof plate is used as a poor lining, and a number of ceramic sheets are laid closely on the front. The reason for using multiple pieces of ceramic is that the ceramic will shatter after being hit by a bullet, and if the whole piece of ceramic is used, the fracture area will be large. But if multiple pieces of ceramics are used, only one piece of ceramics will be broken each time. Others Even if the ceramic pieces are broken, the remaining ceramic pieces are not assumed to be bound by the bulletproof plate bushing and remain in the hole, then it is still possible to resist one or two rounds of bullets (so regardless of the bulletproof vest inserted) plate, or the tank’s ceramic armor is tightly bound together with the outer lining), and not all bullets can hit just one hole, so a ceramic insert can withstand multiple rounds of fire. Now the SAPI bulletproof plate installed by the US military is a ceramic bulletproof plate. In Iraq and Afghanistan, these ceramic plug-in bulletproof plates have saved the lives of many US soldiers, including the 7.62x54r bullets fired by SVD and PKM. The area was a little sore and there was some blood stasis.The protection level of ceramic bulletproof plate is usual NIJ III, or NIJ IV. YF PROTECTOR has been manufacturing and offering the bulletproof products to clients since 2003, every product pass through the SHOOTING TEST, quality is guaranteed.
