PURPOSE: To obtain the subject material excellent in flexural/compression strength, impact resistance and shapability, reduced in a void fraction, and useful for ski boards, etc., by integrally joining fiber woven fabrics to nonwoven fabrics, laminating the produced sheets to each other, impregnating the laminate with a resin monomer, and subsequently reaction-solidifying the impregnated resin monomer. CONSTITUTION: This material is obtained by integrally joining one or two organic nonwoven fabrics to the surface or both the surfaces of each of organic woven fabrics by a needle-punching method, laminating the thus produced sheets to each other in a mold, impregnating the produced laminate with a resin monomer and subsequently reaction-solidifying the impregnated resin monomer, or laminating prepreg sheets preliminarily impregnated with the resin monomer and subsequently reactionsolidifying the impregnated resin monomer. The organic-nonwoven fabric has a METSUKE weight of 20-250g/m<2> , and the material contains 10-60wt.% of the sheets produced by integrally joining the organic nonwoven fabrics to the organic woven fabrics. |
