What is a bulletproof vests?


What is the bulletproof material?

The bulletproof layers are made of metal (special steel, aluminum alloy, titanium alloy), ceramic sheet (corundum, boron carbide, silicon carbide, aluminum oxide), FRP, nylon (PA), Aramid (Kevlar), ultra-high molecular weight polyethylene fiber (doyentrontex fiber), liquid protective material, polyimide fiber (PI) and other materials to form a single or composite protective structure.

Weidu’s bulletproof layers are divided into two main types, the soft armor and the hard armor. The soft plate is mainly made of UHMWPE or Kevlar. And the hard plate is mainly made of aluminum oxide, silicon carbide, or boron carbide. The bulletproof layer can absorb the kinetic energy of warhead or shrapnel, has obvious protective effect on low-speed warhead or shrapnel, and can reduce the damage to human chest and abdomen under the condition of controlling a certain depression.
