a pultrusion apparatus for manufacturing a fiber - reinforced plastic article having a non - linear shape includes a mold configured to receive a partially cured fiber - reinforced plastic article and to form the partially - cured fiber - reinforced plastic article into a spirally wound shape . a drive mechanism is coupled to the mold and configured to rotate the mold such that the fiber - reinforced plastic article is taken up on the mold . an energy source is operatively associated with the mold and positioned so that the partially cured fiber - reinforced plastic article is cured in a spirally wound shape as the article is taken up on the longitudinally extending mold . the pultrusion apparatus allows for continuously shaping a non - linear fiber - reinforced plastic article , obviating the need for any of the work to be done by hand , which may be labor intensive , not as highly reproducible , and potentially contaminating .
