Abstract: This invention relates to a method and apparatus for fabricating continuously a solidified elongated rod or hollow shapes of various geometric cross sections of fiber reinforced plastic having a smooth surface. A plurality of strand-like fibers are wetted with a liquid, heat-hardenable plastic, the fibers are collected together into a plastic-wetted bundle, the bundle is continuously, in intermittent steps, passed through an elongated die, the die being heated in sequential zones of progressively increasing temperature so as to harden the plastic by the time the bundle emerges in rod form from the die.
