Bulletproof glass is actually made by bonding multiple sheets of glass or high-strength organic sheets together with a transparent adhesive. It generally has the following three layers:
① Load-bearing layer: This layer is the first to withstand impact and break. It is usually made of thick, high-strength glass, capable of destroying the bullet or changing its shape, rendering it unable to continue its journey.
② Transition layer: This layer generally uses organic adhesive materials with strong adhesion and good light resistance. It can absorb some of the impact energy and change the bullet's trajectory. A very strong and transparent chemical film is sandwiched between the laminated glass. This not only effectively prevents bullets from being fired but also provides resistance to surge impacts, blasting, shock, and prevents cracking after impact.
③ Safety protection layer: This layer uses high-strength glass or high-strength transparent organic materials with good elasticity and toughness. It can absorb most of the impact energy and ensure that the bullet cannot penetrate this layer.
The most important performance indicator of bulletproof glass is its bulletproof capability. Bulletproof capability is measured from two aspects: one is the safety protection capability, and the other is the lethality of the firearm it protects against.
