How Bullet Proof Glass Works

Bullet proof glass is constructed by layering a tough,transparent plastic known as a polycarbonate with ordinary glass.Through a heating process the layers are bonded or laminated together.When a bullet is fired at it the bullet will pierce the outer layer of glass but the layer of polycarbonate absorbs the bullets energy and stops it before it can pierce the final layer of glass.An average sheet of bullet proof glass can be anywhere from 3/4 of an inch thick to 3 inches thick.The ability to work depends on the thickness of the glass and the force or size of the bullet used.
