Research progress of self-healing intelligent composite materials

Self-healing composite material is an important intelligent composite material. In this paper, according to the recent research progress of the self-healing of composite materials, introduced the two kinds of typical extrinsic self-healing methods, which are microcapsule self-healing and hollow fiber self-healing, the paper expounds the repair mechanism of the two methods of self-healing, self-healing system characteristics and research status. This paper introduces some problems existing in the field of self-healing, and looks forward to the application prospect and development direction of self-repairing intelligent composite materials.
