ABSTRACT:
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 reinforced 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 electroconductive 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 reflecting 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 corresponding conventional molded article, whereby deformation due to molding strain is decreased.
