A novel Lewis acid-catalysed self-healing system is investigated for implementation in epoxy-based fibre reinforced polymer composite materials. Healing is initiated when microcapsules are ruptured at the onset of crack propagation. Results show that a material recovery value of greater than 80% fracture strength is achieved when using a TDCB geometry.
