Puncture- healing thermoplastic resin carbon fiber reinforced composites towards more damage/impact tolerant systems.
NASA Langley Research Center has developed carbon fiber reinforced composites with self-healing properties. The initiation and propagation of damage to carbon composites, such as in aircraft structural components, results in component failure. Typical structural repairs result in damaging practices, where material is ground away and holes are drilled to secure patches, which can act as new sites for damage. This technology exhibits effective self-repair that heals quickly following low to mid velocity impacts, while retaining structural integrity.
