Problems solved by technology

[0004] With the development of science and technology, a large number of modern weapons have been equipped with soldiers. Functions such as infrared tracking and detection, GPS positioning, and infrared thermal sensing have become necessary functions for high-tech weapons. However, UHMWPE fiber composite bulletproof armor is currently only The single protective function has become stretched, gradually unable to adapt to the modern battlefield environment where electronic information technology is ubiquitous

Abstract

The invention relates to a multifunctional composite material bullet-proof board and a preparation method thereof. The bullet-proof board includes multiple structures of a rigid reinforcement layer, an intermediate bullet-proof layer, an anti-back convex layer and a buffer layer. The multiple structures are molded, wherein the rigid reinforcement layer is aramid fiber, high-performance carbon fiber or one or several fiber fabrics impregnated with modified thermosetting resin, the middle bulletproof layer is made of ultra-high molecular weight polyethylene fiber, high-performance carbon fiber mixed fiber fabric and modified thermoplastic resin impregnated , the anti-convex layer is made of high-performance carbon fiber fabric impregnated with modified thermosetting resin, and the buffer layer is made of silicone or polyurethane foam. The invention adopts multi-layer laying and vacuum molding to form a bullet-proof plate with infrared stealth characteristics, high strength, high rigidity, low back convexity, 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,...
