|
摘要
为研究层间混杂复合材料装甲板的防弹性能及其防弹机制,采用钢芯弹侵彻层间混杂复合材料装甲板。以超高分子量聚乙烯(Ultra high molecular weight polyethylene,UHMWPE)纤维、对位芳香族聚酰胺纤维作增强纤维,水性聚氨酯(Waterborne Polyurethane,WPU)树脂和环氧树脂(Epoxy resin,EP)作基体,采用热压工艺制备单向(Unidirectional,UD)结构的层间混杂复合材料装甲板。研究混杂比例、防弹面和树脂基体对混杂复合材料装甲板防弹性能的影响以及弹击后混杂复合材料装甲板的破坏形貌,分析混杂复合材料装甲板的防弹机制,并对复合材料装甲板的破坏机制进行了分析。结果表明:混杂复合材料装甲板的防弹性能优于其任一单一纤维复合材料装甲板;WPU的防弹性能要优于环氧树脂;以UHMWPE纤维复合材料充当防弹面时,混杂复合材料装甲板具有更好的防弹性能;纤维拉伸变形和装甲板分层是纤维复合材料装甲板主要的吸能方式。
In this paper,the steel core projectile was used to penetrate interlaminar hybrid composite armor plate to explore the bulletproof performance and bulletproof mechanism.The types of hybrid reinforcement with unidirectional(UD)structure were ultra high molecular weight polyethylene(UHMWPE)fiber and para-aromatic polyamide fiber,whereas the resin was one of waterborne polyurethane(WPU)and epoxy resin(EP).The effects of hybrid ratio,strike face and resin matrix on ballistic properties were discussed.Also,the fracture morphologies were observed by the stereomicroscopy.Moreover,the failure mechanisms of hybrid composite subjected to the ballistic impact were analyzed.The results show that the bulletproof performance of hybrid composite armor plate is superior to that of the single fiber reinforced composite armor plate,and the bulletproof performance of WPU is superior to that of EP.Furthermore,when UHMWPE fiber composite works as strike face,the bulletproof performance is better.Finally,it can be concluded that the tensile deformation of fiber and the delamination are the major ways of the absorbing energy under the ballistic impact by the steel-core bullet.
