Abstract

An improved solvent-based self-healing system has been developed with complete recovery of fracture toughness (100% healing efficiencies). Microcapsules containing epoxy monomer and solvent have been incorporated into epoxy resin matrices and rupture upon crack damage. More environmentally friendly solvents such as ethyl phenylacetate have proven successful alternatives to a chlorobenzene-based system.
