PURPOSE:To obtain fiber reinforced cylindrical plastics under favorable productivity, by a method wherein a right circular cylindrical laminated body obtained by laminating cloth or preimpregnated cloth is fitted in a female metal mold so as to possess an orientation angle of the fiber to the circumferential direction, which is welded and allotted to the mold through a high pressure fluid in a bag in the inside of the cylindrical laminated body. CONSTITUTION:At the time of manufacture of fiber reinforced cylindrical plastics whose outer diameter is varying in order, a right circular cylindrical laminated body 5 obtained by laminating cloth or preimpregnated cloth is fitted in a female metal mold 6 for the cylinder so as to possess the outside diameter which is either identical with or smaller than the smallest outside diameter of said cylinder and an orientation angle of the fiber to the circumferential direction, a bag 7 having elasticity is loaded on the inside of the righr circular cylindrical laminated body 5 further, a high pressure fluid is made to flow in the bag 7, the right circular cylindrical laminated body 5 is welded and allotted to the female metal mold 6 by pressure, and the cylindrical plastics is molded. The fiber reinforced cylindrical plastics having less dispersion in performance of products is obtained under favorable productivity in this manner. |
