Bulletproof glass is actually made of transparent  materials that bond together many pieces of glass or high strength organic plates. There are generally three layers of structure:


(1) Bearing layer: This layer first withstands impact and breaks down. Generally, glass with large thickness and high strength is used, which can destroy warheads or change the shape of warheads and make them lose the ability to move forward.


(2) Transition layer: Organic material is generally used, which has strong adhesion and good light resistance, can absorb part of impact energy and change the direction of bullet. A very strong and transparent chemical film is sandwiched in the laminated glass. This not only can effectively prevent bullets from firing, but also has the properties of surge shock resistance, explosion resistance, shock resistance and no cracks after impact.

(3) Safety protection layer: This layer is made of high-strength glass or transparent organic material with good elasticity and toughness. It can absorb most of the impact energy and ensure that bullets can not pass through this layer.
