ABSTRACT:
Disclosed are reinforcing fibers, particularly carbon fibers, used for the manufacture of a reinforced plastic composite material which are surface-treated with a resinous composition comprising (A) epoxy resin, (B) condensation product of an acid component comprising unsaturated dibasic acid and a hydroxyl component comprising oxyalkylated bisphenol, and (C) oxyalkylene derivative of phenol. The resinous composition has good dispersibility in water, and the reinforcing fibers surface-treated therewith exhibit improved adhesion to various resin matrixes.
