The bulletproof layer is made of metal (special steel, aluminum alloy, titanium alloy), ceramics (corundum, boron carbide, silicon carbide), glass fiber reinforced plastic, nylon, Kevlar, and other materials to form a single or composite protective structure.
Body armor can be divided into three types: soft, hard and soft-hard composite.
The materials of soft body armor are mainly high-performance textile fibers. These high-performance fibers are much higher than the energy absorption capacity of general materials, giving the body armor a bulletproof function. softness called soft body armor.
The hard body armor is mainly made of metal materials such as special steel plates, super-strong aluminum alloys, or hard non-metallic materials such as alumina and silicon carbide.
The softness of the soft-hard composite body armor is between the above two types. It is a composite body armor with soft material as the inner lining and hard material as the panel and reinforcing material.
