Light multi-layer composite structure bulletproof armor plate and preparation method thereof

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. 本发明公开了一种轻质多层复合结构防弹装甲板，包括防弹面板、防弹背板和设置在两者之间的复合层；其中，所述织物复合层由缓冲层和金属蜂窝板层依次交替组成。本发明通过设置缓冲层和金属蜂窝板层与其它进行配合，在受到弹丸冲击时不仅具有良好的吸能减震效果，同时对其内部填充物产生约束，防止受到弹丸冲击后被分散导致弹孔周边遭到破坏，且所用
