摘　　要：基于轻气炮平板撞击实验，研究石英纤维布的冲击性能。采用胶合叠层材料和螺栓拉紧叠合材料两种试样进行对比实验，探讨了两种试样冲击性能的差异：前者是一种环氧固化的复合材料，而后者是一种具松散结构的“结构材料”。石英纤维布冲击响应实质上是结构体对扰动信号的响应。由此，提出采用变密度粘弹性材料中波的传播方法来分析石英纤维布相关动力学特性。Based on plate impact experiment of light gas gun, the impact property of quartz fiber cloth is investigated in this paper. Impact property comparison experiment was carried out for two kinds of specimens made of adhesive laminated material and the bolted tensioning composite material respectively, the difference of impact properties between two specimens was discussed. The former is an epoxy-cured composite, while the latter is a ＂structural material＂ with a loose. The impact response of quartz fiber cloth is essentially the response of structure to disturbance signal. Therefore, a method of wave propagation in variable-density viscoelastic materials is proposed to analyze the dynamic characteristics of quartz fiber cloth.
