High-performance bulletproof and explosion-proof wallboard and preparation method thereof

Abstract

The invention discloses a high-performance bulletproof and explosion-proof wallboard and a preparation method thereof. The high-performance bulletproof and explosion-proof wallboard comprises an upper graphene sheet layer (1), a lower graphene sheet layer (2), an upper aramid fiber composite sheet layer (3), a lower aramid fiber composite sheet layer (4), an upper ceramic fiber composite sheet layer (5), a lower ceramic fiber composite sheet layer (6) and a foam layer (7). A multi-layer composite structure of the graphene sheet layer, the aramid fiber composite material sheet layer, the ceramic fiber composite material sheet layer and the foam layer is adopted, so that the impact resistance can be effectively improved, the heat conductivity is reduced, a better bulletproof and explosion-proof effect is achieved, and the composite material can be applied to body armor, bulletproof armors, helmets, aerospace, military transport vehicles, military packaging boxes and the like.

Description

technical field [0001] The invention relates to a high-performance bulletproof and explosion-proof wallboard and a preparation method of the wallboard, belonging to the technical field of new materials. Background technique [0002] The traditional explosion-proof and bullet-proof wall panels are composed of rigid aramid fiber composite materials. The foreign trade name of aramid fiber is Kavlar fiber, referred to as K fiber, and the chemical name is polyparaphenylene terephthalamide. Its impact resistance, It has excellent properties such as light weight, and is often used to make bulletproof vests and bulletproof helmets. As the market's requirements for lightweight and higher-performance explosion-proof panels are increasingly prominent, and the traditional explosion-proof and bullet-proof panels of aramid fiber composite materials have high thermal conductivity, they generate a lot of heat and temperature when facing impact, which is harmful to the human body. It is eas...
