Problems solved by technology

[0003] At present, most composite armors are too heavy as a whole, which directly affects the maneuverability of helicopters or tanks on the battlefield, making them vulnerable to projectiles
At the same time, the existing composite armor design is complicated, it is difficult to effectively match and combine multiple layers, and the service life is limited
In addition, when hit by projectiles, once the bulletproof panel is damaged, the bulletproof performance of the remaining parts is limited, and it is difficult to effectively absorb energy when penetrated by bullets, and it is difficult to withstand the continuous blows of multiple projectiles

Abstract

The bulletproof armor plate comprises a bulletproof face plate, a bulletproof back plate and a composite layer arranged between the bulletproof face plate and the bulletproof back plate. Wherein the fabric composite layer is composed of a buffer layer and a metal honeycomb plate layer which are alternately arranged in sequence. The buffer layer and the metal honeycomb plate layer are arranged to be matched with other materials, the good energy absorption and shock absorption effect is achieved when the bullet is impacted, meanwhile, internal filler is restrained, the situation that the periphery of a bullet hole is damaged due to the fact that the filler is dispersed after being impacted by the bullet is avoided, various materials are light materials, and the cost is low. And the maneuverability of helicopters or chariots can be effectively improved.

Description

technical field [0001] The invention belongs to the field of bulletproof technology, and in particular relates to a lightweight multilayer composite structure bulletproof armor plate and a preparation method thereof. Background technique [0002] With the continuous enhancement of modern weapons, the survivability of military helicopters or tanks on the battlefield is severely challenged, so higher requirements are put forward for their armor protection. Based on lightweight, modular and high protection, it is imperative to design a military composite armor with the goal of manufacturability. The metal honeycomb structure composite material has higher stiffness and strength. It is filled with resin-based bulletproof material or ceramic sheet inside, which can be used as a carrier for supporting panel materials. It is lightweight and has good application potential. Due to the high hardness and inherent strength of ceramics, it can cause interface failure response and signifi...
