Zusammenfassung: | PURPOSE: To enhance breaking strength and compression strength by coating the surface of each of prepreg layers with a specific amt. of an elastic polymer film and constituting the polymer film of a meltable or at least sinterable org. polymer B having a specific glass transition point. CONSTITUTION: A fiber composite material has a laminated layer of prepregs each composed of a fiber accumulated layer impregnated with a curable resin A and the respective prepreg layers are bonded by an intermediate layer comprising an elastic polymer film and the polymer film coats 10-90% of the surfaces of the prepreg layers (a) and is present in an amt. of 0.1-20 G per 1 m of the prepreg layers (b) and formed of a meltable or at least sinterable org. polymer B having a glass transition point of the max. 25 deg.C(c). |
