Patent ID: 7972686

Claim:
A composite material comprising at least one polymeric resin composition which is curable at a curing temperature and at least one fibrous reinforcement, wherein the polymeric resin composition comprises: between about 22 weight percent and 25 weight percent, based on the overall resin composition, of bisphenol-F-diglycidyl ether; between about 25 weight percent and 30 weight percent, based on the overall resin composition, of triglycidyl-m-aminophenol; between about 10 weight percent and 15 weight percent, based on the overall resin composition, of insoluble thermoplastic particles consisting essentially of equal weight amounts of particles consisting essentially of polyamide 6 and particles consisting essentially of a copolymer of polyamide 6 and polyamide 12; between about 13 weight percent and 17 weight percent, based on the overall resin composition, of polyethersulfone; and a sufficient amount of a curing agent consisting essentially of an aromatic diamine hardener, to cure said polymeric resin composition at said curing temperature.
