The interface between the fiber and matrix has a major influence on the mechanical properties of fiber reinforced polymers (FRPs). Damages at the interface such as interfacial debonding can cause a reduction in strength and stiffness of FRPs. As a result, the structural capability of the FRP is reduced, and premature failure can result if the damage is not detected and repaired. However, microscopic damage such as interfacial debonding is extremely difficult to detect and repair by conventional methods. The current research suggests that repair of microscopic damage can be accomplished by incorporating repair components into the FRP. This novel concept is that of self-healing. The idea of a self-healing material has led to significant interest in the current literature. Many techniques have focused on the ability to heal microscopic damage in FRPs. In this paper, we present an overview of various self-healing concepts for FRPs, and recent progress and advances that have been made on self-healing of interfacial debonding in FRPs.
