Multi-layer light bulletproof armor with composite structure

The invention discloses a bulletproof armor of a multi-layer light composite structure. The bulletproof armor sequentially comprises a bullet facing layer, an energy absorption and shock absorption layer, a fiber buffer layer and a bulletproof back plate from outside to inside, and the gluing surfaces of the bullet facing layer and the fiber buffer layer are fabric layers. Wherein the bullet facing layer is a ceramic plate wound by PE fibers; the energy absorption and shock absorption layer is formed by alternately arranging ceramic plates wound by PE fibers and metal honeycomb plates filled with high-elasticity resin matrix composites, and the ceramic plates and the metal honeycomb plates are connected in a gluing mode; the fiber buffer layer is a multi-layer fiber fabric; and finally, the fabric is connected with the titanium alloy bulletproof back plate. The bullet-facing layer has good toughness, hardness and weather resistance, the problem that a bullet-facing layer of a traditional ceramic/backboard arm
