摘　　要：研究了四种不同面密度的超高分子量聚乙烯纤维增强层合板(UFRP)的抗高速立方体破片侵彻的能力,并比较了四种不同面密度UFRP的吸能情况。实验结果表明,UFRP薄板和厚板的弹道极限与面密度表现出不同的关系;UFRP正面出现了垂向层状剥离带,而UFRP薄板背面出现了水平层状剥离带,UFRP厚板则未见剥离带出现;高速破片冲击UFRP厚板时,应考虑破片镦粗变形对UFRP厚板吸能以及变形模式的影响。Ballistic tests were performed to investigate the anti-penetration properties of ultra-high molecular weight polyethylene fiber-reinforced laminated plates （UFRP） against high-speed cubic fragments. Energy absorption performances were compared among these fiber-reinforced laminated plates with the four different area densities of 7.11, 15.4, 20. 6 and 30.8 kg/m^2. Experimental results show that the relations of ballistic limit and area density for the thin UFRP are different from those for the thick ones. Vertical strips on the obverse sides of the thin UFRP and horizontal strips on their rear sides can be observed, but no trips can be seen from the thick UFRP. It is required to consider effects of stamp deformation of the fragments on energy absorption and deformation modes of the thick UFRP impacted by high-speed fragments.
