A fiber reinforced plastic molded article containing a porous resin concrete plate as a reinforcing material and a process for the production thereof are described. The porous resin concrete plate is made of 100 parts by weight of a thermosetting resin, 20 to 50 parts by weight of inorganic or organic hollow beads, and 50 to 100 parts by weight of an inorganic fine powder. The fiber reinforced molded article is produced by placing a glass fiber substrate in a mold, mounting a porous resin concrete late on the glass fiber substrate at an area to be reinforced, covering the porous resin concrete plate with a glass fiber substrate, impregnating the glass fiber substrates with a molding resin, and molding.
