摘　　要：设计了具有紫外光辐照引发自蔓延固化特性的脂环族环氧树脂（CEP）与有机硅树脂（ES）的混合树脂体系（CEP-ES）,并以它们为基体实现了碳纤维增强复合材料的快速光固化.研究了以光固化碳纤维复合材料为补片粘接修理金属损伤结构的影响因素.结果表明,有机硅树脂的引入不仅可以有效提高粘接修理的效果,而且可以改善粘接修理结构的耐湿热性能,当ES的质量比为20％ ～ 30％时,粘接修理结构具有最好的承载能力;适当增加复合材料补片的长度和层数可以有效提高粘接修理的效果;双面贴补修理比单面贴补修理具有更好的粘接修理效率.The UV ignited self-propagating curing resin blends, including cycloaliphatic epoxy （CEP） and or- ganic silicone resin modified by epoxy （ES） , were designed. Based on the blends, carbon fiber fabric reinforced composites can be cured quickly by UV radiation. Adhesively bonded repair of damaged metallic structure using UV curable carbon fiber composite material was studied experimentally. According to the results, the introduction of ES can not only increase the load bearing capability of adhesively repaired structure but also improve its resistance of hydrothermal environment. When the weight percent of ES was 20% - 30%, the repaired structure had the best abil- ity of load bearing. Increase of the length and layer number of composite patch can enhance the repair effect. Com- pared with single-sided repair, double-sided repair was the better repair mode.
