复合材料层合板冲击模型研究现状

The developments of impact models for laminated composites

近年来复合材料被广泛应用于防护领域,其中以高性能纤维单层板、陶瓷板、金属泡沫板等单一或几种不同类型复合材料设计构成的层合板结构成为主要的复合材料防护结构形式。总结了复合材料层合板结构在冲击问题研究中分析模型的进展情况,侧重于能量耗散分析模型、应力波分析模型与损伤力学分析模型三个方面,对各分析模型进行了总结与评价,同时也对冲击中的试验方法、测试技术的进展情况进行了回顾。

In recent years, composites have been widely used for structural protection, and composite laminates which are composed of one or some among fiber laminate, ceramic tile, mental foam etc., have become main protecting composite structure. This paper reviews recent progress in impact models of laminated composite structures impacted by the projectiles at both high and low velocities,Which include models for predicting the energy absorption mechanism by composites upon ballistic impact, and the developed stress wave models that are used to gain insight into the effect of the variation of various parameters and the continuum damage mechanics (CDM) based models. The methods of test and instrumentation technology for impact experiments are also discussed.
