摘　　要：超高分子量聚乙烯纤维具有密度低、力学性能高的优点,在防弹衣领域获得了广泛应用。本文综述了人们就该纤维、该纤维的单向布以及其复合材料靶板的力学性能开展的大量实验研究、理论研究和数值模拟研究,从不同角度揭示了该纤维的力学特性;在超高分子量聚乙烯纤维及复合材料靶板的本构模型和破坏准则方面,尚需考虑材料的应变率效应和复杂应力状态的影响,才能进一步揭示该纤维的防护机理,指导超高分子量聚乙烯防护靶板的优化设计。Ultra high molecular weight polyethylene(UHMWPE)fiber has the advantages of low density and high mechanical properties,which has been widely used in the field of bulletproof vests.At present,a lot of experimental,theoretical and numerical studies have been carried out on the mechanical properties of the fiber,unidirectional cloth and composite target plate.These studies revealed the mechanical properties of UHMWPE fibers from different angles.In the aspect of constitutive model and failure criterion of UHMWPE fibers and composite target plates,the strain rate effect and the influence of complex stress state should be considered,to further reveal the protection mechanism of UHMWPE fiber and guide the optimal design of UHMWPE protective target plates.
