Bulletproof glass is a type of glass that has been specially treated to resist high-speed shrapnel such as bullets, artillery shells and explosive fragments, and is often used in military and security fields. This paper will introduce the production principle, types, application fields and advantages and disadvantages of bulletproof glass.

How bulletproof glass is made

The production principle of bulletproof glass is to add a layer or multiple layers of high-strength material on the surface of the glass or the middle layer, so that the glass can withstand strong impact and high-speed shrapnel attack, so as to achieve the effect of bulletproof. Common bulletproof materials are polycarbonate, multilayer glass, ceramics, honeycomb structure, metal alloys and so on. Among them, polycarbonate is one of the most commonly used bulletproof materials at present, because of its high strength, light weight, good transparency, easy processing and other characteristics are widely used.

Types of bulletproof glass

Bulletproof glass can be divided into many types according to different production principles and materials. Common bullet-proof glass includes:

Laminated bullet-proof glass: bullet-proof glass made of multilayer glass sheet and polymer film in the middle pressed together, with high bullet-proof and impact resistance.

Toughened bulletproof glass: on the basis of ordinary glass, through high temperature heating and rapid cooling and other processes, with high impact resistance and bulletproof performance.

Honeycomb structure bulletproof glass: The middle layer of the glass is filled with a kind of honeycomb like material, such as polystyrene foam, aluminum alloy, titanium alloy, etc., to form a kind of lightweight and high strength bulletproof material.

Ceramic bulletproof glass: A bulletproof material formed by pressing ceramic and polymer film together, which has high bulletproof performance and impact resistance.
