  • 摘要: 针对超高分子量聚乙烯(UHMWPE)纤维增强防弹复合材料背部凸起(BFS)较高的不足,本研究充分利用聚酰亚胺(PI)纤维耐高温、高模量的优势,制备了一系列PI和UHMWPE纤维混杂复合材料靶板,研究了混杂靶板的铺层结构和混杂比例对比吸收能(SEA)值和背部凸起(BFS)值的影响,分析了混杂靶板防护作用机制。结果显示:PI纤维的使用可以在不影响SEA值的情况下有效限制BFS值,其中两极铺层结构(H3、UHMWPE/PI)和夹芯铺层结构(H4、PI/UHMWPE/PI)表现出混杂正效应,两种结构的SEA值和BFS值分别可达193.2 J·m2/kg,17.40 mm和208.9 J·m2/kg,17.77 mm,表现出优异的防弹性能。
