Abstract
Abstract An extruded frame member includes an elongated molded body of a one-piece construction having at least one elongated sheet-like wall having at least one elongated projection formed on one side of the wall and extending longitudinally of the molded body. A reinforcing wire is embedded in and extends along the elongated projection. The molded body is made of a thermoplastic resin. The reinforcing wire includes a bundle of fibers joined together by a thermosetting resin impregnated in the fiber bundle. The fibers have a higher melting point than the thermoplastic resin.
