PURPOSE:To continuously and inexpensively produce a thick-walled fiber reinforced thermosetting resin molding having no air bubbles remaining therein by pultrusion. CONSTITUTION:In the production of a molding, a hard mold 6 equipped with a plurality of branch passages 11 having required passage cross sections on the inlet side thereof and the main passage 10 communicating with all of the branch passages 11 and having the cross section almost corresponding to the total cross section of all of the branch passages is prepared. Uncured resin compd. impregnated fibers 5 are divided on the inlet side of the curing mold to be drawn into a plurality of the branch passages 11 and guided to the main passage 10 during period when the resin compd. infiltrated into the reinforcing fibers 5 is uncured in the hard mold to be made to integrally meet with each other. Continuously, during a period when the reinforcing fibers 5 are passed through the main passage, the resin compd. is cured under heating and a molding 9 composed of a fiber reinforced thermosetting resin having a predetermined cross section is drawn out of the main passage 10 of the hard mold 6. |
