The production of tough, electrically conductive carbon fiber composite laminates for use in airframes

A simple method has been developed to simultaneously increase the electrical conductivity and the fracture toughness of carbon fiber reinforced composite laminates through the same process method. The key component of this function integration is a porous phenolphthalein poly(ether ketone) film that is perforated and surface-loaded with silver nanowires. By interleaving this film into the composite laminate, both the electrical conductivity and the fracture toughness have been improved.
