Anti-explosion Performance and Failure Mechanism of Fiber-Metal Laminates

  • 摘要: 采用爆炸冲击摆锤系统,对玄武岩纤维-铝合金层合板和碳纤维-铝合金层合板进行了爆炸加载实验。实验中通过改变炸药质量获得不同的加载冲量,分析了载荷冲量、结构组合形式以及纤维类型对纤维金属层合板变形/失效模式的影响。实验中观察到分层、基质失效、金属撕裂、塑性大变形等典型的变形失效模式。实验结果表明:随着冲量的增加,纤维金属层合板中铝合金层的塑性变形以及纤维层的损伤区域不断增大;纤维金属层合板相对于单一的金属层合板具有更优异的抗冲击性能。
