PURPOSE:The title composition having improved softness, handleability, moldability, and productivity, without sticking, obtained by impregnating a strand with a composition comprising a thermosetting resin having a specific softening point and an epoxy resin. CONSTITUTION:(A) A strand, preferably carbon, boron, silicon carbide, or kevlar fibers, is impregnated with (B) a composition of (a) 100 parts by wt., of a thermosetting resin, preferably an epoxy, unsaturated polyester, phenolic, or polyimide resin, having a softening point <=60 deg.C and (b) 5-60 parts by wt., preferably 14- 40 parts by wt., of an epoxy resin, preferably a polyether, having terminal epoxy, groups or unsaturated polyester resin, having an average molecular weight >=5000, preferably >=10,000.
