摘要
采用落重冲击试验方法研究了航空上常用的铺层形式为［Ｏ２／９Ｏ２／４５２／－４５２］ｓ的先进复合材料（ＣＦＲＰ）低能冲击损伤问题。重点讨论了落重冲击后分层损伤形貌、冲击能量Ｗ与分层面积Ａ之间的关系以及基体韧性对ＣＦＲＰ抗冲击性能影响。
The damage of delamination of CFRP laminates with the stacking sequence of [O2/902/452/-452 ]s,were investigated by drop-weight impact tests. The damaged images and relationship between impact en--.ergy and delamination area as well as the effect of matrix toughness on CFRP impact resistance were discussed in detail in this paper.
