IS A BULLETPROOF VEST ALSO STAB PROOF ?- CHINABALLISTIC.COM

While some bulletproof vests may offer limited protection against stabbing or slashing attacks, they are not specifically designed to be stab-proof. Bulletproof vests are primarily designed to protect against high-velocity projectiles such as bullets, typically from firearms.

What is bullletproof vest ?

Bulletproof vests are usually made with layers of strong synthetic materials, such as Kevlar or similar fibers, which are designed to absorb and disperse the energy of a bullet, reducing the chances of it penetrating the vest and reaching the wearer’s body. These materials are effective against the impact and force associated with bullets but may not be as effective against sharp objects like knives or other stabbing implements.

What is stab-proof vest ?

Stab-proof vests, on the other hand, are specifically designed to protect against knife attacks and other sharp objects. They often incorporate additional layers or materials, such as chainmail or rigid plates, to provide resistance against punctures and slashes.

How to choose bulletproof and stab-proof vest ?

While there may be some overlap in the protection offered by bulletproof and stab-proof vests, it’s important to use the appropriate type of vest depending on the specific threats you anticipate. If you require protection against both bullets and stabbing attacks, there are some specialized vests available that offer a combination of bullet and stab resistance. These vests typically incorporate additional layers or materials to provide the necessary protection against both types of threats.

Choosing a bulletproof and stab-proof vest involves considering several factors to ensure you select the right vest for your needs. Here are some key points to consider when making your decision:

Level of Protection: Determine the level of protection you require based on the potential threats you may face. Bulletproof vests are rated according to different ballistic protection levels, such as NIJ (National Institute of Justice) standards in the United States or similar standards in other countries. These levels indicate the vest’s ability to withstand different types of ammunition and their velocities. Stab-proof vests are often rated based on their resistance to specific types of blades and the amount of force applied. Assess the potential threats you are likely to encounter to determine the appropriate level of protection for your vest.

Combination or Individual: Decide whether you need a vest that provides both bulletproof and stab-proof protection or if you require separate vests for each threat. Combination vests offer convenience but may compromise on certain aspects of protection compared to specialized vests.

Material and Design: Consider the materials used in the vest. For bulletproof protection, common materials include aramid or similar synthetic fibers. Stab-proof vests may use additional materials like aramid or rigid plates.

HOW DOESE CERAMIC BULLETPROOF PLATE WORK ?-Chinaballistic.com

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.

THE DEVELOPMENT HISTORY OF POLICE BULLETPROOF VEST– Chinaballistic.com

The police body armor is composed of a jacket and a bulletproof layer. The bulletproof layer is mainly made of metal and other protective materials, which can absorb the kinetic energy of the warhead and reduce the speed of the warhead, thereby protecting the human body. So, what kind of process did the body armor go through? What are the relevant properties of the inner body armor? Let’s take a closer look at the history of bulletproof vests and related characteristics.

Special bulletproof clothing Lightweight bulletproof clothing is a kind of personal protective military uniform used for protecting the human torso from projectiles or shrapnel, mostly in the shape of a vest. Bulletproof clothing made of bulletproof layer and jacket is a kind of individual protective military uniform used for protecting the human torso from projectiles or shrapnel. The thickness of the bulletproof layer is determined by the balance between protection performance and wearing comfort according to different objects. Soldiers wearing alone can significantly reduce battlefield mortality and injury rates.

Police bulletproof clothing is developed on the basis of armor. During the First World War, 80% of the total casualties on the battlefield were caused by low- and medium-velocity stray bullets or fragments, and experts were inspired by ancient armor to develop alternative bulletproof suits in the late war. In World War II, casualties caused by shrapnel still accounted for about 60%. People paid more and more attention to the development of bulletproof clothing. In the early 1940s, the United States and some Western European countries began to develop alloy steel and aluminum alloys. , Chin alloy, glass fiber reinforced plastic, ceramics, nylon and other materials bulletproof clothing, and used in the battlefield.

In the 1960s, the second generation of bulletproof clothing that replaced high-quality steel with high-quality chemical fiber materials began to appear. Since the 1970s, bulletproof clothing has undergone new developments. Body armor can be divided into three types: soft, hard and soft-hard composite. The material of the soft body armor is mainly high-performance textile fibers. These high-performance fibers are much higher than the energy absorption capacity of general materials, giving the body armor the bulletproof function. softness, called soft body armor. The protection level of soft body armor is usual NIJ IIIA AND below.

HOW MANY TYPES OF BULLETPROOF SHIELD ARE THERE ? – Chinaballistic.com

A bulletproof shield, as the name suggests, is a shield with a certain bulletproof ability. The traditional bulletproof shield is a rectangular sheet-like object with an arc, usually with a handle on the back that is easy to hold. While defending against the enemy’s attack, just lift the shield in front of the user to cover the head and body, thus providing comprehensive protection for the user. However, with the continuous progress of the protection industry, various protection products are also changing with each passing day, and the functions, appearance and use design are also constantly improving, and they are more and more suitable for various usage scenarios and in line with human usage habits.

There are many materials that can be used to make bulletproof shields, including aramid, polyethylene, ceramics and steel plates.

Bulletproof shields are generally classified by size and can be divided into ultra-small (450mm × 650mm), small (550mm × 650mm), medium (550mm × 1000mm), large (600mm × 1300mm) and super-large (600mm × 1750mm). Bulletproof shields also have strict protection standards. The National Institute of Justice of the United States has set 7 levels of bulletproof shields – Level I, Level IIA, Level II, Level IIIA, Level III, Level IV and Special class. Level I can protect against 0.22-inch pistol and 0.38-inch special pistols; Level IIA can protect against 0.357-inch Magnum and 9mm pistols (lower muzzle velocity types, such as 0.380-inch ACP bullets); Level II can protect against 0.357-inch horses Gnum and 9mm pistols (higher muzzle velocity types, such as 9mm Parabellum); Class IIIA can protect against 0.44-inch Magnum and 9mm submachine gun shots; Class III can protect against 0.308-inch Winches Special full armor and 7.62×39mm bullets; IV grade can protect 0.30-06 inch bullets, 7.62mm NATO standard bullets and 7.62×54mmR bullets; Special grade is customized for special bullets. There are many opportunities for SWAT to use bulletproof shields. However, since most of the SWAT police use medium-sized bulletproof shields, and sometimes tactical lights are added, they are basically IIIA-level, and III-level is also used when necessary, but the total quality of the two is very different. In terms of appearance and design, it can be divided into ordinary hand-held bulletproof shields, folding bulletproof shields, briefcase-type bulletproof shields, ladder-type bulletproof shields, and cart-type bulletproof shields.

Hand shield

Hand-held shields are usually equipped with 2 handles on the back, which can be used by left-handed or right-handed users at the same time, and are also equipped with bullet-proof glass viewing windows or sight glasses for easy observation of external conditions. Hand-held shields are mainly suitable for combat scenarios with complex terrain. For example, hand-held bulletproof shields are more flexible to use in narrower stairs or passages, and can also be better matched with weapons such as guns. Trolley Bulletproof Shield

The cart-type bulletproof shield is equipped with a cart, which is more labor-saving for long-distance movement. In addition, like the hand-held bulletproof shield, it is equipped with a handle on the back, which can be used by hand, and is also equipped with a bulletproof glass sight glass. Generally, shields with higher defense levels are usually heavy and require a cart for long-term use.

The cart-type bulletproof shield is mainly suitable for relatively open and flat combat scenarios. When using, the shield can be moved freely over a long distance by placing the shield on the cart, which is more labor-saving. It can also be used by hand when the cart cannot be used due to changes in space and terrain.

Ladder Bulletproof Shield

There is a special structure behind the ladder bulletproof shield that can be turned into a ladder to deal with complex terrain, such as helping users to view and control the environment at higher altitudes when necessary. At the same time, the bottom of the shield is also equipped with wheels, which is more convenient and labor-saving to move.

Briefcase Bulletproof Shield

Briefcase-style bulletproof shields are bulletproof shields that look similar to briefcases. They usually look like a very common PR bag, but they can be quickly deployed into bulletproof shields in critical situations. The weight of this shield is only about 5 kilograms, and it has a good defensive effect on the protection of light weapons such as pistols.

HOW DOES THE BULLETPROOF VISOR/MASK WORK ? -CHINABALLISTIC.COM

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.

NEW BULLETPROOF MATERIAL-POLYUREA-CHINABALLISTIC.COM

In daily life, if we are careful enough, we will find that many skyscrapers, truck covers, oil platforms, and bulletproof equipment have a common material – polyurea. The popularization and promotion of polyurea is said to have originated from the experiments of a group of Italians. They tried to free fall the polyurea-coated watermelon from a height of 45 meters, and the watermelon bounced back when it landed, and its appearance was intact. In order to further verify the protective ability of polyurea, some people also tried to spray polyurea on eggs and tested, and the eggs were also intact. With its excellent protective properties, polyurea has become more and more widely used in various fields from heavy industry to agriculture, especially in the field of protective products, its application is also more and more promising.

Polyurea is formulated from specific raw materials in a specific proportion. Its specific material formulations are kept secret commercially, but the basic ingredients can be identified as a combination of isocyanate and polyol resin. Polyols primarily act as plasticizers, and when the two components are combined, they polymerize to form a long-chain molecule. Long chains of molecules are intertwined with each other to form an indestructible material called polyurea. In addition, these long-chain molecules are stretchable and have high flexibility, which also endows the polyurea material with ultra-high tensile and tear resistance.

In addition, polyurea has many performance advantages, such as:

Quick-drying – Polyurea coatings sprayed on surfaces such as various instruments and equipment can be dried and set in seconds and are ready for use.

Very high wear and compression resistance.

Good chemical resistance.

Super airtight and waterproof.

Does not contain VOCs, CFCs, solvents, etc., and does not cause any pollution to the environment.

It is precisely because of these characteristics of polyurea that it has a lot of attention to its use method and application. At present, polyurea is usually coated on the surface of objects by thermal spraying, which is time-critical because once the two components of the coating are combined, the reaction starts immediately and cannot be reversed. In the process of use, the two coatings need to be pressed into a special spray gun through a heated hose, the two are quickly mixed at the moment of spraying, and then quickly dried and formed in a few seconds.

THE IMPROVEMENT AND APPLICATION OF POLYETHYLENE -CHINABALLISTIC.COM

In recent years, product research and development technology has been continuously improved, and various products are constantly innovating in terms of performance, materials, packaging and production technology. For bulletproof products, the limited protective performance and high weight have always been difficult obstacles to improve the performance of bulletproof products. Therefore, scientists and researchers in the field of bulletproof protection have always been involved in finding and developing new materials. At the same time, attempts are made to improve and enhance the performance of the original materials, and the new polyethylene (PE) is one of the new high-performance materials improved through new technologies.

The high-strength and functional polyethylene tape is made of special high-molecular-weight polyethylene, which is currently the strongest polyethylene material in the world. It is an upgraded version of ultra-high molecular weight polyethylene, so in addition to all the characteristics of ordinary ultra-high molecular weight polyethylene materials, it also has excellent characteristics that ultra-high molecular weight polyethylene does not have, such as high strength under the same weight And functional polyethylene tape is 11 times stronger than steel, and at the same time, compared with ordinary UHMWP, it has higher corrosion resistance, UV resistance and creep resistance as well as good thermoplasticity.

The excellent performance of this super polyethylene comes from its special processing technology and manufacturing process. Super polyethylene is to melt and press ultra-high molecular weight polyethylene particles to synthesize polyethylene film, and then stretch it to a thickness of 50-60um. At this time, the polyethylene molecular chain will be fully stretched and regular under strong pulling force. Arranged together, giving it far superior characteristics than ordinary ultra-high molecular weight polyethylene materials. These ultra-high molecular weight polyethylene films are then laminated together to obtain what we call super PE materials.

The bulletproof product made of super PE has a super energy absorption effect, it can disperse and absorb the kinetic energy of the bullet, so as to intercept the bullet and have a good bulletproof effect. Therefore, this super PE has been applied to bulletproof helmets, bulletproof inserts, and bulletproof vests and other bulletproof products.

In addition, this new type of super PE has also been applied in many fields, such as:

Textiles and composites – some textiles are made with this super PE, and composites synthesized with this type of fabric have strong compression resistance. For example, adding super PE fibers to some carbon-containing composite materials and glass materials can enhance the strength and compressive ability of the composites.

Ropes, nets and cables—-Super PE has super high tensile strength, combined with its light weight, it is used as the best material for making ropes, cables, etc. In addition, its good corrosion resistance makes it more widely used.

In addition, super PE can also be used in the manufacture of air containers, sails, etc. As long as it is a product with high requirements for strength and light weight, super PE can participate.
