摘要/Abstract

摘要： 由于超高的比拉伸强度,超高分子量聚乙烯(Ultra-High Molecular Weight Polyethylene,简称“UHMWPE”)纤维复合材料在冲击防护领域获得了极大的关注。本文通过可同时产生破片和爆炸波加载装置的设计,实验观察了UHMWPE纤维复合材料在联合冲击加载下的失效行为。实验发现,UHMWPE复合材料在联合加载下失效模式复杂,包括层间脱层、屈曲与褶皱、侵彻穿透、纤维烧蚀等。基于失效模式的分析,总结了UHMWPE纤维复合材料在破片和爆炸波联合加载下失效破坏的四个典型阶段。

Abstract: Due to the extremely high specific strength, the ultra-high molecular weight polyethylene (UHMWPE) fiber reinforced laminates are widely employed in protective armors. In this paper, the failure modes of UHMWPE laminate panel under explosive loading are experimentally investigated. Firstly, an explosive device that can simultaneously produce blast and fragments is designed. And then, the deformation and failure characteristics of the UHMWPE panel under the loading of the explosive device are gained and analyzed. The panel exhibits multiple failure modes, including the delamination, buckling, bubbling, fragments penetration and erosion. Based on the deformation characteristics, the failure progress of the UHMWPE laminate panel under explosive loading can be divided into four typical stages.
