Bulletproof glass is a composite material made of glass (or organic glass) and high-quality engineering plastics by special processing. It is usually transparent material, usually including polycarbonate fiber layer sandwiched in ordinary glass layer.

Bulletproof glass produced by different manufacturers is different. But it is basically a common glass layer with polycarbonate material layer, this process is called lamination. In this process, a substance similar to ordinary glass but thicker than ordinary glass is formed. Polycarbonate is a rigid transparent plastic with a thickness ranging from 7mm to 75mm of bullet-proof glass. Bullets fired on bullet-proof glass will break through the outer glass, but the polycarbonate glass material layer can absorb the energy of the bullet, thus preventing it from penetrating the inner glass. These large pieces of bullet-proof glass have been used for public use during World War II, usually 10.0 to 12.0 centimeters thick and extremely heavy.
