The epoxy resin used as the binder, which is made by mixing this with fibers, includes bisphenol diglycidyl ether and its oligomer, novolac type epoxy resin, dimer acid-modified flexible epoxy resin, aliphatic epoxy resin, etc. Commercially available products are fine. In addition to unsaturated polyester resins, those modified with epoxy resins and the like can also be used. The acrylic ester resin is preferably an ester resin having unsaturated groups all around the acrylic oligomer. As cellulose fibers, wood bulbs, cotton fibers, etc. are used. There are no restrictions on the length or shape of the fibers. The binder content is preferably 2 to 65%, preferably 1% to 5 to 20%. The binder 8i@ should be selected to have good affinity with the thermosetting resin to be impregnated.
