高强度和高模量碳纤维复合材料失效模式比较

介绍了高模量碳／环氧树脂、碳／双马树脂和高强度碳／环氧3种复合材料抗拉伸、压缩、弯曲、层间剪切等力学性能的测试情况，用微观和宏观照片对比了不同强度、模量和不同树脂的失效模式差异，包括失效部位、失效的层次和类型。指出现行复合材料测试标准在测试高强度和高模量碳纤维复合材料性能时存在的问题。同时用测试数据对比了高模量碳纤维分别与双马来西亚胺5405和环氧树脂5224匹配后的性能，以及高强度碳纤维与环氧BA9913匹配后的性能。

Failing Mode Comparing with High Module and High Strength Carbon Fiber Composite Material

This paper introduces the mechanic parameter testing for three kinds of composite materials, including high module carbon/epoxy resin, high module carbon/bismaleimide resin, high strength carbon/epoxy resin. The difference of failing modes for high module and high strength composite are showed in detail using photos in both normal view and micro view. The paper also indicates the problem associated with the testing specification, as well as the mechanic characters for the three composites by listing the measuring data.
