Abstract

A study of the healing of interfacial debonding in fiber-reinforced plastics is performed. In the composite, a microencapsulated healing agent and a solid chemical catalyst are dispersed within the polymer matrix layer of fiber surface. Healing is triggered by crack propagation through the microcapsules, which then release the healing agent into the crack plane. Subsequent exposure of the healing agent to the chemical catalyst initiates polymerization and bonding of the crack faces. Self-healing is demonstrated on flat tensile specimens of neat epoxy and unidirectional fiber-reinforced plastics. The ratio of fracture strengths of the virgin and healed materials is used to quantitatively measure crack healing.
