  • 摘要: 碳纤维(Carbon fiber,CF)增强环氧树脂(Epoxy resin,EP)基复合材料因其优异的抗冲击性而被广泛应用在飞机结构件。考虑到飞机在飞行过程中部分结构会遭受多次冲击的工况,设计CF/EP复合材料层合板的多次冲击及冲击后压缩试验。通过对多次冲击的力学响应曲线分析及内部损伤图观测,得到不同冲击载荷对复合材料多次冲击的力学性能影响及多次冲击过程中的主要损伤机制和损伤传播模式。在此基础上,对冲击后的剩余压缩强度及失效形貌进行了分析,得到了CF/EP复合材料层合板在冲击后的损伤容限及失效模式。结果表明:冲击次数的提高将导致复合材料的吸能性下降,抗冲击性下降。在多次冲击过程中,复合材料层合板的损伤模式为自下而上。此外,随冲击能级变化,复合材料在冲击后压缩过程中的主要损伤模式有所变化。
