Is bulletproof glass really bulletproof?
Bulletproof glass is a new type of transparent material that is specially processed and compounded by 3 or more pieces of glass and high-quality transparent plastic. Its structure is glass + film + glass + film + glass, which is a special glass compounded by high temperature pressing, which also has the effect of light transmission of ordinary glass, and also provides protection against small arms shooting.

The reason why bulletproof glass can be bulletproof mainly depends on the effect of the film in it. When the bulletproof glass is shot by a weapon, the bullet will gradually pass through the three layers of bulletproof glass, so as to achieve the function of protecting safety. The following situations may occur.
1. When the bullet hits the surface of the bulletproof glass, the direction of the bullet may be directly changed or the bullet may be directly broken.
2. The bullet penetrated the surface of the bulletproof glass and changed its shape, the kinetic energy was greatly slowed down, and the middle layer could not be penetrated.
3. The bullet has changed shape or is still intact, and penetrated the middle layer of the bulletproof glass. Since the impact energy of the bullet is slowed down during the penetration process, the bullet cannot penetrate the high-strength glass in the inner layer of the bulletproof glass.

Bulletproof glass is actually bulletproof. According to the current Chinese bulletproof glass standard, the gun types corresponding to the bulletproof glass level can withstand at least 3 shots without penetrating. For example: 19mm bulletproof glass can be used at a distance of 5m, using a 54-type 7.62mm pistol to effectively shoot 3 rounds without penetrating.
