摘要

摘要: 复合材料结构的设计要求和使用经验提出了复合材料体系损伤阻抗和损伤容限性能表征的需求。在试验研究的基础上,本文作者指出长期以来一直使用的CAI (冲击后压缩强度) 的物理意义比较含混,有时可能误导材料研究和设计选材,同时提出应分别用典型层压板静压痕力-凹坑深度曲线的最大压痕力F_max来表征损伤阻抗性能,用凹坑深度-压缩破坏应变曲线门槛值CAIT(Compression failure strain After Impact Threshold)来表征损伤容限性能,同时给出了测试方法的建议。

Abstract: The need to characterize damage resistance and damage tolerance behaviour of composite laminates was proposed by the design requirements and usage experience. Based on the experimental study, the authors pointed out that traditional CAI (by NASA standard) could not guide development of materials and structural design correctly. In the paper, it was proposed that the damage resistance behaviour could be characterized by the maximum contact force F_max of the contact force-dent depth curve of typical laminates and the damage tolerance behaviour could be characterized by the threshold CAIT(Compression failure strain After Impact Threshold) of the dent depth -compressive failure strain curve of typical laminates. In the meanwhile the suggestion for their measurement methods was proposed as well.
