Abstract

The invention discloses a piece of tough and invisible bullet-proof glass which comprises a bearing layer, a bullet-proof layer and an outer protecting layer which are adhered from inside to outside in sequence, wherein a layer of liquid crystal dimming membrane is added between the bullet-proof layer and the outer protecting layer; the bullet-proof layer is made of polyethylene glycol terephthalate layer; the outer protecting layer is a glass fiber layer; the thickness of the bullet-proof glass is within 3-8mm. The tough and invisible bullet-proof glass disclosed by the invention is very high in stability and high-strength high breakage toughness, and can be widely applied to bullet-proof transparent window of aircrafts and ground vehicles.

Description

technical field [0001] The invention relates to the field of new materials, in particular to a tough and invisible bulletproof glass. Background technique [0002] Bulletproof glass is a kind of special glass with high safety performance that can be attacked by a certain equivalent bomb explosion without breaking away from the frame, keeping intact or non-penetrating damage. Bulletproof glass is a composite material obtained by special processing of glass or plexiglass and high-quality engineering plastics. It is usually a transparent material, including polycarbonate fiber layers sandwiched between ordinary glass layers. It has the appearance of ordinary glass and the performance of transmitting light, and has a protective effect on the attack of hard materials. [0003] Currently, the bullet-proof glass that is the most common on the market can be divided into two types: the first one is made of multiple layers of glass and a layer of carbonate plate using polyethylen...
