This study examines the interfacial debonding behavior of fiber-reinforced polymers (FRPs) encompassing self-healing and the performance of this self-healing system. Healing is accomplished by incorporating a microcapsulated healing agent and catalytic chemical trigger within a coating layer on the surface of the fiber strands. Self-healing is demonstrated on single edge notched tensile (SENT) specimens of unidirectional FRPs and the healing efficiency was evaluated by the critical fracture loads of healed and virgin specimens. To investigate the release of healing agent from microcapsule during interfacial debonding, a ultra-violet (UV) fluorescent dye was added to the healing agent and post-fracture specimens were examined by a optical microscope under UV light.
