摘　　要：本文对国产碳纤维增强双马来酰亚胺树脂复合材料进行了高温老化力学性能测试和分析,通过扫描电子显微镜分析了高温老化对碳纤维/双马复合材料力学性能的影响。结果表明,老化1 000h的力学性能未出现明显下降趋势,纤维与树脂基体粘接牢固,界面完好,该复合材料的高温老化性能优异。Carbon fiber reinforced bis - maleimide （BMI） composite material was processed a thermal - oxidation aging treatment at 150℃ condition. The effects of thermo - oxidative aging on mechanical properties of carbon fiber reinforced BMI composites were investigated by SEM with the combination of flexural strength test and inter - laminar shear strength （ILSS） test. The results showed that the mechanical properties maintained good values, which indicated that the composite material has perfect interface. Carbon fiber was strongly bonded with BMI resin and this composite material has splendid mechanical properties at 150℃ after thermal aging process.
