Structural composition of bulletproof glass
Bulletproof glass is actually made by bonding multiple sheets of glass or high-strength organic sheets together with a transparent glue. Generally have the following three-tier structure:
1 bearing layer: This layer is first subjected to impact and rupture. Generally, the glass with large thickness and high strength can damage the warhead or change the shape of the warhead, so that it loses the ability to continue to advance.
2 transition layer: generally adopts organic glue material, which has strong adhesive force and good light resistance, can absorb part of impact energy and change the direction of bullet growth. A very strong and transparent chemical film is placed in the laminated glass. This not only effectively prevents the bullets from being fired, but also has the properties of resisting surge, anti-explosion, anti-vibration and no cracks after impact.
3 Safety protection layer: This layer is made of high-strength glass or high-strength transparent organic material. It has good elasticity and toughness. It can absorb most of the impact energy and ensure that bullets cannot pass through this layer.
The most important performance indicator of bulletproof glass is the bulletproof capability. The index of bulletproof capability is measured in two aspects, on the one hand, the ability to protect the security, and on the other hand, the ability to protect the firearms.
