Problems solved by technology

[0003] However, the comprehensive performance of composite materials used for bulletproof walls is generally not high, which is reflected in poor heat resistance, low comprehensive mechanical strength, low creep resistance, and inability to effectively resist the impact of bullets. Only by increasing the number of layers or Weight to achieve defensive effect, reducing practicality

Abstract

The invention discloses a bulletproof wall body composite material, and a preparation method thereof, and belongs to the technical field of composite material. The preparation method is capable of solving problems in the prior art that the technical comprehensive performance is always poor. The bulletproof wall body composite material comprises, by weight, 6 to 8 parts of pre-fabricated disorderednetted high-strength silicon-based fiber, 1 to 5 parts of basalt fiber, 9 to 20 parts of untwisted silicon-based yarn, 34 to 61 parts of poly-p-phenylene terephthamide thermal-plastic resin, and 10 to 11 parts of FRP thermosetting resin. The preparation method comprises steps of impregnation, preformation, solidification moulding, traction, and cutting. The bulletproof wall body composite material is excellent in heat resistance and bullet resistance; it is confirmed by experiments that the back surface trauma height is 0; the weight is lighter; and better bullet impact resistance at equal layer numbers is achieved.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a bulletproof wall composite material and a preparation method thereof. Background technique [0002] Bulletproof materials mainly include para-aramid fiber (aramid fiber) and ultra-high molecular weight polyethylene fiber. The specific strength and specific modulus of aramid fiber are 10 times that of steel, and the specific strength of ultra-high molecular weight polyethylene fiber is about 1.5 times higher than that of aramid fiber. A single fiber or bundle of filaments cannot play the role of bulletproof. Only when the fibers are arranged and integrated according to certain rules can they effectively resist the attack of bullets or fragments. The same kind of fiber can choose different weaving processes according to different purposes. Some bulletproof cloths are used for anti-fragmentation, some are used for anti-steel jacket warheads, and some are used for anti...
