Abstract

The invention relates to a multifunctional composite material armor plate and a preparation method thereof. The armor plate comprises multiple structures of a rigid reinforcing layer, a middle bulletproof layer, a back bulge prevention layer and a buffer layer and the multiple structures are formed by die pressing, wherein the rigid reinforcing layer is formed from a fiber fabric, which is made of one or a plurality of aramid fibers and high-performance carbon fibers, and modified thermosetting resin by impregnation; the middle bulletproof layer is formed from a mixed fiber fabric, which is made of ultrahigh molecular weight polyethylene fibers and high-performance carbon fibers, and modified thermoplastic resin by impregnation; the back bulge prevention layer is formed by a fiber fabric, which is made of high-performance carbon fibers, and modified thermosetting resin by impregnation; the buffer layer is made of organic silicon or polyurethane foam. The invention provides the armor plate which is prepared by adopting multilayer laying and vacuum die-pressing integrated forming and has the characteristic of infrared stealth and has high intensity, high rigidity, low back bulge property, corrosion resistance and heat resistance.

Description

technical field [0001] The invention relates to a multi-functional composite material bullet-proof plate and its manufacturing method, in particular to an anti-bullet plate with infrared stealth characteristics, high strength, high stiffness, low back convexity, excellent corrosion resistance and heat resistance, and has both GPS positioning and infrared remote sensing. And other multifunctional composite bulletproof panels. Background technique [0002] With the continuous deepening of high-performance fiber research, its application range and depth in the field of protection have gradually expanded, which has played an important role in promoting the improvement of the quality and function of bulletproof materials. Since the 1970s, high-performance fiber composites have been widely used in the field of armor protection. High-performance fiber composite materials play the main characteristics of the respective strength and toughness of reinforcing fibers and matrix resins,...
