Embodiment 1

[0012] Preferred embodiment 1 of the present invention provides a graphene bulletproof helmet, which is a three-layer sandwich structure bonded together by an adhesive. The layer is a sponge structure composite reinforced by silicon carbide, graphene and aluminum. The preparation method of the sponge composite is: mixing graphene and silicon dioxide-coated aluminum powder with alcohol solution, wherein graphene accounts for the mixed solution The percentage by weight of silicon dioxide is 7%, and the percentage by weight of silicon dioxide-coated aluminum powder in the mixed solution is 4%; then get silicon carbide powder equal to the weight of graphene, and add it to the above mixed solution, and ultrasonically mix and stir for 1.5 ~ 2 hours to get a mixed suspension; immerse the open-cell polyurethane sponge into the mixed suspension, and apply pressure to discharge the gas in the open-cell polyurethane sponge, and continue ultrasonic oscillation for 6-8 hours; then put the c...

Abstract

The invention provides a graphene bulletproof helmet. The helmet is of a three-layer sandwich structure bonded together through a bonding agent. Aramid fiber prepreg cloth and high-modulus high-strength polyethylene fiber no-woven cloth are arranged on the inner layer and the outer layer correspondingly, and the core layer is a silicon carbide, graphene and aluminum mixed enhanced sponge structurecomposite body. A polyurethane sponge is used firstly to serve as a carrier to carry out sponge structural dispersion combination on the graphene and the silicon carbide, a non-solid porous frameworkis formed, pores are filled with an aluminum alloy melt, in the high-temperature filling process, a polyurethane sponge is heated and decomposed to generate gas, silicon dioxide wraps aluminum powderfor melting, the combination strength with the aluminum alloy melt is improved, certain porosity is formed in the sponge structure finally formed as well, sufficient elastic deformation space is provided for graphene, and product bulletproof performance is obviously improved.

Description

technical field [0001] The invention relates to a bulletproof helmet, in particular to a graphene bulletproof helmet. Background technique [0002] The applicable objects of bulletproof helmets are mainly combat personnel equipped with troops, and there are mainly two types of helmets, Japanese style and German style. In addition to the old-fashioned steel helmets, the main materials for making bulletproof helmets are ultra-high molecular weight polyethylene fiber and aramid. kg. Infantry bulletproof helmets can resist broken shrapnel and direct bullets, and are generally required to resist the impact of 9mm caliber pistol projectiles and shrapnel 5m away. The bulletproof helmets made of high-strength aluminum alloy, glass fiber reinforced plastic, chrome corundum and boron carbide used by the Military Supplies Research Institute of the Ministry of Logistics can effectively prevent Type 54 pistols and Type 51 ordinary projectiles from harming the human head. [0003] At p...
