摘要

对复合材料层合板的反复低速撞击损伤进行了落重试验研究。以乙烯基酯树脂浸渍的碳机织布和玻璃机织布为材料,进行了单次冲击、5次重复冲击和10次重复冲击,能量水平为U=20J。采用非破坏性方法、脉冲热像仪和全息干涉法分析了单次和多次撞击后的最终损伤,以评估多次撞击对损伤区域演变的影响。

Damage evaluation of repeated impact events on glass/carbon hybrid composites
Drop-weight experiments studied the damages due to repeated low-velocity impacts of hybrid composite laminates. The laminate made by carbon woven fabric and glass woven fabric impregnated by vinyl ester resin was subjected at single impact, at 5 repeated impacts and 10 repeated impacts, for an energetic level of U=20J. The final damage after the single and repeated impact events was analysed by no-destructive methods, Pulse Thermography and Holographic Interferometry to evaluate the influence of the multi-hit events on the damaged area's evolution.
