An in-house developed Lewis acid-catalysed self-healing system, comprised of solid-phase metal triflate catalysts and diglycidyl ether bisphenol A (DGEBA) epoxy resin, is employed to achieve full fracture toughness recovery of the fibre reinforced polymer composite material. Mechanical testing of the healed material clearly shows a ductile failure, a failure mechanism not typically associated with inherently brittle materials such as epoxy.
