WHAT IS THE FUNCTION OF BULLETPROOF VEST ?-CHINABALLISTIC.COM
Similar to the role of ancient armor, it is used as a defensive weapon for offense. Bulletproof vest is a personal body protector used to absorb the impact force of bullets fired by guns or explosive fragments. Different types have different operating principles and are divided into full soft and reinforced/composite.
- All-soft bulletproof vest, made of many layers of tightly woven aromatic polyamide or ultra-high molecular polyethylene, can withstand pistol, shotgun bullets or fragmentation attacks from explosives such as grenades, as well as long-distance Automatic rifle attack, the advantage is that the user can move flexibly, light and comfortable
- Reinforced/composite bulletproof vest, with a metal or ceramic protective layer, can withstand close-range shooting of rifle bullets, but it is easy to crack. The advantage is that it can withstand more powerful weapons than pistols, usually law enforcement officers or security personnel. Full soft bulletproof vest is used, while soldiers on the battlefield or special police officers who need to face weapon attacks at close range often use reinforced/composite bulletproof vest.
Bulletproof vest usually has two functions:
- Bulletproof fragments: High-speed fragments produced by the explosion of various explosives such as bombs, mines, artillery shells and grenades are one of the main threats on the battlefield. According to the survey, the threats faced by soldiers in a battlefield are in order of magnitude: shrapnel, bullets, blast shock waves and heat. Therefore, the function of bulletproof sheet should be emphasized very much.
- Prevent non-penetrating damage: The bullet will produce a great impact after hitting the target, and the damage caused by this impact on the human body is often fatal. This kind of injury does not appear to be penetrating, but it can cause internal injury, which is life-threatening in severe cases. Therefore, preventing non-penetrating damage is also an important aspect of reflecting and testing the ballistic performance of bulletproof vest.
On the one hand, the wearing performance requirements of bulletproof vest means that the bulletproof vest should be as light and comfortable as possible without affecting the bulletproof ability, and people can still complete various actions flexibly after wearing it. In addition, due to its special use environment, bulletproof vest should also consider the compatibility with other weapons and equipment.
