A catalyst-free, self-healing material system was developed by researchers at the University of Illinois, USA, offering a less expensive and more practical way to repair composite materials ranging from airplane fuselages to wind-farm propeller blades. The system is equipped with chlorobenzene microcapsules. The self-healing of epoxy materials with encapsulated solvents can prevent further crack propagation. in fracture tests, this new system recovered as much as 82% of original fracture toughness.
