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.

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 curable composite material that may be used in applications where both high mechanical performance and high electrical conductivity are required. The curable composite material includes two or more layers of reinforcement fibers that have been infused or impregnated with a curable matrix resin and an interlaminar region containing carbon nanomaterials, e.g. carbon nanotubes, and insoluble polymeric toughening particles. The carbon nanomaterials are significantly smaller in size as compared to the polymeric toughening particles. The polymeric toughening particles are substantially insoluble in the matrix resin upon curing of the composite material, and remain as discreet particles at the interlaminar region after curing. Methods for fabricating curable composite materials and cured composite structures are also disclosed.

Abstract: A curable prepreg ply formed by applying two outer resin films to the top and bottom surfaces, respectively, of a layer of resin-impregnated reinforcement fibers. The outer resin films contains insoluble toughening particles, and partially soluble or swellable toughening particles, but the resin matrix which impregnates the reinforcement fibers does not contain the same toughening particles. The insoluble toughening particles are insoluble in the resin matrix of the resin films upon curing of the prepreg ply. The partially soluble or swellable toughening particles are partially soluble or swellable in the resin matrix of the resin films upon curing of the prepreg ply, but remain as discreet particles after curing.
