Problems solved by technology

However, since metal and non-metal materials are in different fields, they do not have a deep understanding of the protection mechanism, performance and interface combination of each other. Therefore, metal and non-metal composite bulletproof materials are still rarely studied in China.

Abstract

The invention discloses a bulletproof composite board and a preparation method thereof. The bulletproof composite board comprises a bullet-ward face, an interface and a backing face, wherein the bullet-ward face is a bulletproof metal material layer, the backing face is a high-performance fiber composite material layer, and the bulletproof metal material layer and the high-performance fiber composite material layer are glued together through the interface. The bulletproof metal material layer is made of a bulletproof metal plate or a bulletproof titanium alloy material. The high-performance fiber composite material layer is selectively formed by laminating one or more layers made of one or more of an ultra high molecular weight polyethylene non-woven cloth laminated board, an aramid fiber non-woven cloth laminated board and an aramid fiber woven cloth laminated board. The finished bulletproof composite board has excellent bulletproof performance, and compared with metal boards on the same bulletproof level, the weight of the bulletproof composite board is reduced by 30% or over, and meanwhile, breakage resistance is improved; and compared with high-performance fiber composite boards, the cost is reduced by about 50%, and meanwhile, the depths of bullet pits are decreased.

Description

technical field [0001] The invention relates to the field of bulletproof materials, in particular to a composite bulletproof plate and a preparation method thereof. Background technique [0002] At present, the main bulletproof panels are divided into two types: metallic materials and non-metallic materials. [0003] Bulletproof plates made of metal materials are mainly high-strength bulletproof grade steel plates or bulletproof grade titanium alloy plates. Relying on their own high hardness and certain toughness, they can destroy the bullet structure and bullet core and prevent bullets from penetrating. The price is relatively low, but the weight is large and the impact is dispersed. If the energy is not good, it is easy to cause secondary damage. [0004] Non-metallic bulletproof panels are mainly high-strength fiber laminates, relying on the fabric structure to transmit impact energy as soon as possible, while the fracture and deformation of high-strength fibers absorb i...
