ABSTRACT:
A method and an apparatus for continuous shaping of carbon-fiber-reinforced plastic tubes, wherein a carbon fiber prepreg in tape form impregnated with a thermosetting resin is laminated on and around a mandrel, then the laminated carbon fiber prepreg tape on the mandrel is preheated, and the thus preheated laminate is pulled in and through a hot die together with the mandrel so as to subject the carbon fiber prepreg to gelling, curing and shaping into a predetermined carbon-fiber-reinforced plastic tube, the pulling operations being continuously carried out by alternate motion of first and second grasping mechanism in such a manner that the pulling force is generated in the second grasping mechanism, while the first grasping mechanism still retains its pulling force, and finally the gellation of the laminate is completed at the first half part of the hot die.
