摘　　要：为抑制、修复树脂基缠绕复合材料裂纹扩展行为,开展了微胶囊化树脂基复合材料缠绕单向板的裂纹自修复与基体强化研究。分析了微胶囊的结构及作用机理,试验研究了微胶囊型自修复复合材料的静态强度、断裂韧性等力学性能。结果表明:修复过程可以有效改善缠绕复合材料的基础力学性能。微胶囊质量分数为10%、平均粒径为10μm时,复合材料的力学性能最佳。与不含微胶囊的复合材料相比,最大拉伸和压缩性能分别提高了82.82%与30.05%。To suppress and repair the crack propagation behavior of resin-based wrapped com-posites,the crack self-repairing and matrix strengthening of the microencapsulated resin-based composite wrapped unidirectional plate were studied.Firstly,the structure and mechanism of ac-tion of the microcapsules were analyzed.Furthermore,mechanical properties of microencapsulated selfrepaired composites,such as static strength and fracture toughness,were tested and explored.Results indicated that the repair process can effectively improve the basic mechanical properties of wrapped composites.When the mass fraction of microcapsules is 10%,and the average grain di-ameter is 10μm,mechanical properties of the composite are optimum.Compared with composites without microcapsules,its maximum tensile and compressive properties increased by 82.82%and 30.05% respectively.
