THERMOPLASTIC COMPOSITE MATERIAL COMPRISING POLYAL ETHER SULFONE MATRIX RESIN

摘要

Composites comprising structural fibers such as carbon fibers and, as the matrix resin, an aryl ether sulfone polymer comprising a 4,4'- bis- phenylsulfonyl biphenyl and at least two additional arylene structural units. The matrix resins exhibit improved toughness and stress crack resistance and a reduced tendency toward crystallization. The polymers are soluble and film-forming from solution, and may be used as coating and impregnating resins for producing the laminates and fiber- reinforced composites of this invention.
