    摘要: Provided are a manufacturing device and a molding method for a rotary-component reinforcement carbon fiber reinforced plastic, the manufacturing device molding a ring comprising a carbon fiber reinforced plastic for reinforcement of a rotary component having a circular cross section as an outermost layer of the rotary component, wherein, in a mold in which a unidirectional prepreg comprising a thermosetting resin and carbon fibers and being wound on the rotary component is heated and cured, an annular pressure source, which applies a desired external pressure to the unidirectional prepreg utilizing its own thermal expansion, exists between a cavity of the mold and the unidirectional prepreg. The manufacturing device and molding method are adaptable to mass production, exhibit an excellent mass productivity with inexpensive facilities, enable a low manufacturing cost because of the unnecessity of a disposable secondary material and the repetitive reuse of a member to be used, and are capable of evenly applying a molding pressure in a central direction of the rotary component.
