摘　　要：树脂基复合材料具有轻质高强的特性,在航空航天、武器工业领域被广泛应用,研究表明自修复技术应用于树脂基复合材料可有效减缓损伤,达到性能修复的目的。课题组前期采用环氧树脂与固化剂分别微胶囊化的方法,开展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。本工作主要延续前期成果,针对含有修复剂的环氧树脂基复合材料结构进行修复效果的物理评估,检验胶囊在基体中分布状态及粘结作用,并探讨了胶囊匹配性对结构的影响。Resin based wound composite materials have the characteristics of lightweight and high strength,and are widely used in the aerospace and weapon industries.Research has shown that self-healing technology applied to resin based composite materials can effectively reduce damage and achieve the goal of performance repair.The research group used the method of microencapsulation of epoxy resin and curing agent separately in the early stage to carry out the study of crack self-healing and matrix strengthening of microencapsulated resin based composite materials wrapped around unidirectional plates.This work mainly continues the previous achievements,conducts a preliminary evaluation of the repair effect on the structure of epoxy resin based composite materials containing repair agents,examines the distribution and bonding effect of capsules in the matrix,and explores the influence of capsule compatibility on the structure.
