PROBLEM TO BE SOLVED: To provide a molding method for an FRP hollow structure capable of certainly molding a strong FRP hollow structure having a beam structure therein without requiring a core removing process. SOLUTION: Since an inner shell preform cured up to a curing depth of 10% by a preheating curing process C has high dimensional precision by the rising of surface hardness, it certainly functions as a core when a contour preform is molded by a contour preform molding process D. Further, since the surface of the inner shell preform is softened and fluidized to develop stickiness by reheating the inner shell preform by a main heating curing process E, the inner shell preform is well bonded to the contour preform to be certainly integrated therewith. As a result, the strong FRP hollow structure having the beam structure therein is certainly molded using the inner shell preform as a structural member. COPYRIGHT: (C)2005,JPO&NCIPI |
