摘　　要：论述了复合材料在使用过程中常常出现磨损、腐蚀、断裂等损伤,致使表面或内部出现微裂纹,导致材料的使用寿命缩短甚至造成设备故障。学者们将自修复微胶囊掺入到水泥建材、金属防护涂层、沥青改性以及玻璃纤维等复合材料中,使其服役周期、自愈能力、热稳定性以及力学性能得到大幅度提升。对水泥建材类、金属防护涂层类、沥青改性类以及玻璃纤维类微胶囊复合材料的制备方法及作用机制进行了总结和评价,并对不同微胶囊复合材料的修复剂类型、性能特点以及研究方向进行比较,指出了微胶囊复合材料在耐低温、复配以及愈合速度等方面亟待解决的问题,以期为相关的未来研究提供参考价值。This paper discusses that wear,corrosion,fracture and other damages often occur in the use of composite materials,resulting in microcracks on the surface or inside,shortening the service life of materials and even causing equipment failure.Scholars have incorporated self-healing microcapsules into cement building materials,metal protective coatings,asphalt modification,glass fiber and other composite materials,so that their service cycle,self-healing ability,thermal stability and mechanical properties have been greatly improved.This paper summarizes and evaluates the preparation methods and mechanism of cement building materials,metal protective coatings,asphalt modified and glass fiber microcapsule composites,and compares the types,performance characteristics and research directions of different microcapsule composites.The paper pointed out the problems to be solved in low temperature resistance,compounding and healing speed of microcapsule composites,in order to provide reference value for related future research.
