ABSTRACT OF THE DISCLOSURE ELECTROCONDUCTIVE NONWOVEN FABRIC-RESIN COMPOSITE ARTICLES AND METHOD FOR PRODUCTION THEREOF There are provided an FRP molded article and a method for production thereof , which has the properties of uniformly reflecting and shielding electromagnetic waves, The molded article comprises a compression-molded laminated structure composed essentially of an electroconductive nonwoven fabric- resin composite surface layer (3), a woven fabric-resin composite intermediate layer (2) and a fiber material rein- forced resin substrate layer (1), wherein the nonwoven fabric composite layer substantially contains no bubbles. The molded article can be produced by placing, on a mold, an electro- conductive nonwoven fabric substantially containing no liquid resin material, a woven fabric or a prepreg thereof, and a mixture of a reinforcing fiber material and a liquid crosslink- curable resin composition; subjecting the molding materials to depressurization treatment in the mold; and then subjecting the molding materials to compression molding. The molded articles can be advantageously used, for example, as reflect- ing dish antennas as well as shielding sheets or boards for electromagnetic waves. In the preferred embodiment, the molded article contains about 90% or less of the cured resin component by weight of the resin component of the correspond- ing conventional molded article, whereby deformation due to molding strain is decreased.
