ABSTRACT:
In a method and apparatus for continuous shaping of carbon-fiber-reinforced plastic tubes, a carbon fiber prepreg in tape form impregnated with a first thermosetting resin is laminated on and around a mandrel; the laminate provided on said mandrel is preheated; and the preheated laminate is pulled in and through a hot die together with the mandrel, during which it is gelled, cured, and shaped into a carbon-fiber-reinforced plastic tube, wherein a second thermosetting resin is uniformly supplied onto the outer circumference of the laminate in a resin squeezing zone in the hot die.
