在对含低速冲击损伤复合材料层合板压缩破坏研究的基础上 ,探讨了层合板在低速冲击损伤后的修补问题 ,提出了开口、金属填充以及机械修补等 3种修补方法 ,并考核了它们对改善板的压缩强度的作用。结果表明 ,所提出的修补方法均有较好的效果 ,其中的机械修补方法成倍地提高了层合板的压缩强度 ;同时还进一步证明了 ,子层失稳、扩展是导致低速冲击后层合板承压能力下降的重要因素。 Based on the research on the compressive failure of composite laminates with low velocity impact damage, the repairing problems of laminates after low speed impact damage were discussed, and three methods of repairing such as opening, metal filling and mechanical repair were proposed, Improve the compressive strength of the plate role. The results show that all the proposed methods have good effect. The mechanical repairing method of this method doubled the compressive strength of the laminated plates. At the same time, it was further proved that the sub-layers became unstable and the expansion caused the low- An important factor in the decrease of pressure capacity.
