从复合材料结构设计的角度 ,指出了目前在韧性复合材料评定技术中存在的问题 ,特别是指出了用冲击后压缩强度值作为判别复合材料韧性的缺点 ,提出了应采用损伤阻抗和损伤容限共同评定复合材料韧性的观点。对 7种不同韧性的复合材料进行了冲击与静压痕等试验 ,在对试验数据分析的基础上 ,确定了对损伤阻抗最敏感的损伤参数 ,提出了描述损伤阻抗的物理量和测试方法 From the point of view of composite structure design, the existing problems in the evaluation of ductile composite materials are pointed out. In particular, it is pointed out that the compressive strength after impact is used to judge the toughness of composite materials. It is suggested that the damage resistance and damage tolerance Joint assessment of composite toughness point of view. The impact and static indentation tests on seven different toughness composites were carried out. Based on the experimental data, the most sensitive damage parameters were determined, and the physical quantities and test methods to describe the damage resistance were proposed
