Abstract:
A curable composite material having high z-direction electrical conductivity. The curable composite material includes two or more layers of reinforcement carbon fibers that have been infused or impregnated with a curable matrix resin and an interlaminar region containing at least conductive nano-sized particles, e.g. carbon nanotubes, and a light-weight carbon veil. According to another embodiment, the interlaminar region further contains polymeric toughening particles. Methods for fabricating composite materials and structures are also disclosed.

Abstract:
A resin system containing: (i) a thermosetting resin precursor component comprising one or more multi-functional epoxy resin precursor(s) having a functionality of at least three, preferably wherein said precursor(s) are selected from a tri-functional epoxy resin precursor and/or a tetra-functional epoxy resin precursor; (ii) a thermoplastic polyamide particle component wherein the polyamide particles have a melting temperature TPA; and (iii) one or more curing agent(s), wherein the resin precursor component, the thermoplastic particle and the curing agent(s) are selected such that gelation of the epoxy matrix during the cure cycle of the resin system occurs at a gelation temperature TGEL which is at or below TPA.
