Abstract
A method and apparatus for twisting and/or postforming a plastic rod reinforced with continuous reinforcing fibers is described. A rod with continuous reinforcing fibers already in a helical configuration may be postformed by this method and apparatus with or without additional twist being imparted. A fiber reinforced rod with continuous longitudinally aligned unidirectional fibers may also be postformed by this method and apparatus by twisting and then postforming the rod. The reinforced plastic rod is more easily postformed if the reinforcing fibers are conformed to a helical configuration in which the number of helices in a given length of the rod is correlated to the diameter of the rod and to the degree of bend to be postformed in the rod. The method for this and the rod with the helical fibers is described.
