Prepreg for making a composite having high elongation and heat resistance and process for making such composite with the prepreg |
摘要 |
A prepreg for making a composite is disclosed. The prepreg comprising reinforcing fibers impregnated with a resin composition comprising (A) an epoxy resin, (B) a reaction product of an epoxy resin and a butadiene-acrylonitrile copolymer having carboxyl groups on at least both terminals of the molecular chain of the copolymer, and (C) 4,4'-diaminodiphenylsulfone as a curing agent. A composite produced by curing this prepreg is high in both tensile elongation and heat resistance and is used with advantage as primary and secondary structural materials in aircraft.
