摘　　要：通过改进光固化树脂的引发体系,实现了不透光碳纤维增强树脂基复合材料的快速光固化。将双[(3,4–环氧环己基)甲基]己二酸酯和甲基丙烯酸丁酯混合构成互传聚合物网络,并以此为光固化复合材料树脂基体,研究了组分比例对碳纤维增强树脂基复合材料的拉伸性能的影响。研究发现,当双[(3,4–环氧环己基)甲基]己二酸酯和甲基丙烯酸丁酯以85/15的质量比混合时,复合材料具有最好的拉伸性能。湿热环境会导致复合材料拉伸性能的明显下降,但是,甲基丙烯酸丁酯的引入可以提高复合材料的耐湿热性能。当其质量分数为25%时,湿热处理后拉伸性能的下降最小。The resin matrix composites reinforced with opaque carbon fiber were cured quickly by UV radiation by modifying the initiation system. The bis[（3,4-epoxycyclohexyl）methyl] adipate and butyl methacrylate were blended as interpenetrating polymer network（IPN）. As resin matrix, the effect of composition of IPN system on the tensile property was investigated. According to the results, when the weight ratio of bis[（3,4-epoxycyclohexyl）methyl] adipate and butyl methacrylate is 85 / 15, the composite has the best tensile property. The hydrothermal treatment can lead to the obvious decrease of the tensile property. Incorporation of butyl methacrylate can enhance the composites＇ resistance of hydrothermal treatment. When the mass fraction of the butyl methacrylate is 25%, the decrease of the tensile property of the composites is the least.
