How do bulletproof vests work?

Time : 2022-11-11 Hits : 125

We all know that bulletproof vests are designed to cope with the attack of firearms, and they have been regarded as a necessity for us when working or living in a danger environment. Many people are curious about how bulletproof vests work to resist bullets. This issue should be started with the structure, material and working principal of ballistic vest.

Bulletproof vests are usually made of special materials, such as Kevlar, PE, nylon, and Alumina. According to materials, bulletproof can be divided into two categories, soft armor and hard armor, whose structures and functional principles are different from each other.

1.Soft armor

Soft armor is mainly made of nylon, aromatic polyamide synthetic fiber, and ultra-high molecular weight polyethylene, which are all high-performance fibers with ultra-strong energy absorption capability low density, high strength, great toughness, and excellent molding property. With such materials used, soft armor is much lighter, softer and easier to wear. The impact of bullets against the fiber layer will develop into tensile force and shear force, during which the impact force produced by bullets can be dissipated to the periphery of the impact point, following the consumption of most of kinetic energy. This is how soft armor works in resisting bullets. But soft body armor is not as strong as its hard counterpart (only three levels, NIJ IIA, II, and IIIA are available in the market), which can only stop pistol and shotgun rounds reliably. But when it comes to bigger threat, we should turn to hard armor.

2.Hard armor

Hard armor refers to the combination of soft armor and hard plates. These plates are mainly made of metals, ceramics, high-performance composite plates, and other hard materials. Equipped with heavy and hard plates, hard armor is more heavy and inflexible than soft armor, while its protective capability has been improved remarkably. In a shooting incident, the bullet firstly hits and cracks the hard plate, during which most of its energy is dispersed, and then the high-performance fibers consume the rest of kinetic energy. Hard body armor is far stronger than soft body armor thanks to the impenetrability of its internal plates. They can stop more powerful rifle bullets, such as AP (armor piercing) and API (armor-piercing incendiary).

Above is all the clarification for bulletproof vests. If there are still some questions, welcome to contact us.
