摘　　要：根据改进的拉伸性能和层间剪切性能的测试方法,对不同树脂基材、不同纤度织物以及不同纤维增强方式的芳纶复合材料的拉伸强度和层间剪切强度进行性能及测试均匀性的研究。通过测试发现,氰酸酯基复合材料具有最高的拉伸强度,环氧基树脂具有最高的层间剪切强度且数据稳定性较好。不同纤度的芳纶复合材料中100 tex力学性能最好,但数据均匀性差。单向增强比织物增强具有更高的拉伸强度和层间剪切强度,但数据均匀性差。According to the improved test method of tensile properties and interlaminar shear properties, the tensile strength and interlaminar shear strength of aramid composites with different resin substrates, different fabric sizes and different fiber reinforcement methods were studied.It could be found that the cyanate ester based composite has the highest tensile strength, and the epoxy resin has the highest interlaminar shear strength, and the data stability is good.Among the aramid composites with different fiber sizes, 100 tex has the best mechanical properties, but the data uniformity is poor.Unidirectional reinforcement has higher tensile strength and interlaminar shear strength than fabric reinforcement, but the data uniformity is poor.
