Abstract

High-performance fiber resin matrix composites are disclosed which are comprised of a first layer comprising reinforcing filaments coated with a thermosetting resin composition and a discrete second layer of a thermoplastic resin. When the composite layers are matched to provide certain minimum strength and elongation properties, composites of unusually high impact strength and resistance to impact damage are achieved which retain their high performance properties over a range of temperatures and environmental exposures.
