Co-continuous, thermoplastic toughened epoxy matrix composites were developed with the goal of using the thermoplastic phase as both a toughening agent and a healing system. Our strategy involved the damage-triggered release of non-toxic, solvent-based healing agents that locally swelled and flowed the thermoplastic phase to repair the cracked region. Methods were developed to incorporate this novel self-healing resin system into a unidirectional, carbon fiberepoxy prepreg using a bench-top prepregger. We observed significant fatigue life extension of these high fiber volume fraction self-healing composites without a reduction in tensile strength.
