Bulletproof composite armor and preparation method thereof
The invention discloses a bulletproof composite armor and a preparation method thereof, and belongs to the technical field of composite materials. The preparation method of the bulletproof composite armor comprises the following steps: 1) mixing boron carbide, high-thermal-conductivity carbon nano fibers, phenolic resin and high-purity water, uniformly stirring to obtain composite slurry, and carrying out spray granulation to obtain a composite raw material; (2) filling the composite raw material prepared in the step (1) into a carbon fiber woven bag, sewing the bag, putting the bag into a mold, carrying out cold pressing to form a green body, and carrying out high-temperature hot-pressing and sintering on the green body to obtain a composite ceramic plate; and 3) hot-pressing and compounding the composite ceramic plate prepared in the step 2), aramid fiber cloth and an ultra-high molecular weight polyethylene back plate in a high-temperature autoclave to obtain the bulletproof composite armor. The cracking of the ceramic plate in all directions can be prevented, and the high-temperature resistance of a crack stopping layer is improved.
一种防弹复合装甲及其制备方法，属于复合材料技术领域。该防弹复合装甲的制备方法包括以下步骤：1)将碳化硼、高导热纳米碳纤维、酚醛树脂与高纯水混合，搅拌均匀得到复合浆料，再经喷雾造粒，得到复合生料；2)将步骤1制得的复合生料装填入碳纤维编织袋内，之后缝合，放置在模具中，冷压形成生坯，生坯再经高温热压烧结成复合陶瓷板；3)将步骤2制得的复合陶瓷板、芳纶纤维布、超高分子量聚乙烯背板在高温热压罐中热压复合，得到防弹复合装甲。本发明能够对陶瓷板全方位限位止裂，并且增加了止裂层的耐高温性能。
