Experimental Study on Post Impact Compression Properties of Laminated Composite Laminates
摘要: 针对T800级碳纤维增强复合材料铺层递减层压板，开展了不同过渡段斜率(1:5，1:10和1:20)冲击后压缩试样的冲击性能、冲击后压缩性能以及疲劳损伤扩展过程试验研究，试验结果表明过渡段斜率对冲击性能和冲击后压缩性能有较大影响，同时获取了冲击后压–压疲劳试样损伤扩展规律。
Abstract:
For T800 carbon fiber reinforced composite laminates, the impact properties, compression prop-erties and fatigue damage propagation process of specimens with different transition slopes (1:5, 1:10 and 1:20) were studied. The results show that the transition slope has a great influence on the impact properties and compression properties, and the compression fatigue behavior after impact was obtained The damage propagation law of the specimen is analyzed.
