Abstract
Pre-impregnated composite material (prepreg) is provided that can be cured/molded to form composite parts having high compression strength under hot and wet conditions, as well as, high damage tolerance and interlaminar fracture toughness. The matrix resin includes a thermoplastic particle component that includes polyamide particles which are composed of the polymeric condensation product of a methyl derivative of bis(4-aminocyclohexyl)methane and an aliphatic dicarboxylic acid.
