Abstract

The invention discloses a multilayer bulletproof member. The bulletproof member comprises a metal / ceramic crack-proof reflecting layer, a fiber / elastomer composite energy absorption layer and a two-dimensional fabric protection blunt injury layer. The three-layer structure is formed by stacking in sequence. By the adoption of the multilayer bulletproof member and the preparation and application ofthe multilayer bulletproof member, the high strength, hardness and good impact toughness of the bulletproof member are ensured through the comprehensive performance of all components.

Description

technical field [0001] The invention relates to the technical field of bulletproof mechanical damage composite materials, in particular to a multi-layer bulletproof component and its preparation method and application. Background technique [0002] With the rapid development of the global economy and the rapid advancement of the world's military technology, countries have gradually increased the requirements for the bulletproof impact protection performance of bulletproof materials. Compared with traditional homogeneous armor, traditional protective armor has certain protective performance, but it still has the disadvantages of large mass, high thickness, weak design, low performance, and is not conducive to installation, carrying and management. Modern bulletproof materials pay more attention to Therefore, the research and development of anti-mechanical injury materials in today's society is gradually developing towards the trend of light weight, comfort, low cost, multi-fu...
