摘　　要：选用热塑性的水性橡胶、水性聚酯、水性聚氨酯作为基体树脂,超高分子量聚乙烯(UHMWPE)纤维作为增强纤维,采用热压工艺制备单向正交结构的防弹先进复合材料层压板。基于弹道侵彻试验和力学试验研究热塑性树脂基体对防弹先进复合材料弹道响应及力学行为的影响。研究结果显示:相比单一的热塑性树脂体系,以热塑性树脂混合体系作为基体制备的UHMWPE复合材料具有更优异的抗弹道侵彻性能、更高的拉伸破坏强度和层间剪切破坏强度,这是由于混合树脂体系中的UHMWPE纤维具有更高的可利用效率;此外,基于横向压缩诱导的间接张力机制和弹道侵彻下的大变形行为诱导的膜力效应,UHMWPE纤维复合材料的抗弹道侵彻性能与其准静态下的拉伸断裂强度、层间剪切强度呈现正相关的关联机制。Three kinds of thermoplastic resin,waterborne rubber,waterborne polyester and waterborne polyurethane,were used as resin matrix,and ultra-high molecular weight polyethylene(UHMWPE)fiber was worked as reinforcement.The unidirectional cross-ply structure bulletproof advanced composite laminates were prepared by hotpressing process.The influences of thermoplastic resin matrix on mechanical behavior and ballistic response of bulletproof advanced composites were studied through ballistic impact test and mechanical test.The results show that:compared with the single thermoplastic resin system,UHMWPE fiber composite,which was fabricated with the thermoplastic resin mixed system,has better anti-penetration performance,higher tensile strength at break and higher interlaminar shear strength at break.This phenomenon is due to the higher utilization efficiency of UHMWPE fiber in the mixed resin system.Moreover,according to indirect tension mechanism induced by transverse compression together with membrane force effect caused by the larger deformation under ballistic impact,the antipenetration performance of UHMWPE fiber composite is positively correlated with mechanical properties under quasi-static state,including tensile strength at break and interlaminar shear strength.
