对特定铺层的5224/CF3052平纹织物复合材料层合板进行了低速冲击和冲击后拉伸、压缩及弯曲试验。探讨了层合板在冲击试验过程中的损伤过程、特征和机理；分析了凹坑深度对层合板冲击后拉伸、压缩和弯曲强度的影响规律。结果表明：冲击后拉伸、压缩及弯曲强度降幅分别为60．9％、50．4％及28．4％，冲击后拉伸强度降幅最大，应引起注意。与冲击后压缩试验结果类似，凹坑深度与冲击后拉伸、弯曲剩余强度关系曲线存在拐点现象。
對特定鋪層的5224/CF3052平紋織物複閤材料層閤闆進行瞭低速遲擊和遲擊後拉伸、壓縮及彎麯試驗。探討瞭層閤闆在遲擊試驗過程中的損傷過程、特徵和機理；分析瞭凹坑深度對層閤闆遲擊後拉伸、壓縮和彎麯彊度的影響規律。結果錶明：遲擊後拉伸、壓縮及彎麯彊度降幅分彆為60．9％、50．4％及28．4％，遲擊後拉伸彊度降幅最大，應引起註意。與遲擊後壓縮試驗結果類似，凹坑深度與遲擊後拉伸、彎麯剩餘彊度關繫麯線存在枴點現象。

The tensile、compressive and flexural strength were tested for 5224/CF3052 plain weave composite laminates after impact.The influence of dent depth on the tensile、compressive and flexural strength of laminates was researched .The results show that decreasing amplitude of tensile、compressive and flexural strength were 60.9%,50.4%,and 28.4%,the biggest decreasing amplitude was tensile strength after impact which should be noticed .There is infection in the relation curve of the dent depth and tensile ,compressive,flexural strength.
