<P>PROBLEM TO BE SOLVED: To provide a structure of a component formed of a fiber-reinforced composite material which increases the rigidity of the component that is formed by integrating a region formed of FRP and needing rigidity and a region formed of resin and needing no rigidity particularly but including a rugged shape, and improves the productivity of the component, and to provide a method of manufacturing the component formed of a fiber-reinforced composite material. <P>SOLUTION: The component 1 comprises a cylindrical frame member 1B and rugged structures 1A, 1C. The cylindrical frame member 1B is formed of a thermoplastic resin which is reinforced with continuous fibers by reaction injection molding for a structural material and has increased rigidity. The rugged structures 1A, 1C are formed of thermoplastic resins which are the same series of the thermoplastic resin and have high weldability and the rugged structures cover openings at both ends of the cylindrical frame member. Particularly in the method of manufacturing the component 1, during a time when the thermoplastic resin used in reaction injection molding for the structural material is not polymerized yet, the same series of the thermoplastic resin is subjected to injection molding to a mold cavity surrounding the cylindrical frame member 1B to obtain the component 1 of high rigidity. <P>COPYRIGHT: (C)2012,JPO&INPIT |
