PROBLEM TO BE SOLVED: To provide a contouring molding method capable of contouring, efficiently while retaining a high degree of morphological freedom, a three-dimensional shape for a high-strength molding by using a moldable preform; and a fiber-reinforced resin molding.SOLUTION: Moldable preforms 1 are laminated, and after a laminate molding material 5 has been preliminarily compression-molded by using a preliminary laminate molding mold, the laminate molding material 5 mounted atop a heating platen 8 within a preheating mold 6 is preheated with near infrared rays by using a near infrared emitter 7, whereas, on the other hand, a molding mold 9 provided as a contouring mold having a three-dimensional shape is preheated so as to elevate the temperature thereof to the curing temperature of a thermosetting resin constituting the moldable preforms 1. Next, the laminate molding material 5 is stored within the preheated molding mold 9, and the laminate molding material 5 is compressed by the molding mold 9. The resin material 4 adhered to a woven fabric substrate 3 is thus cured so as to bond interlayer gaps of the laminate molding material 5 and to preserve the shape thereof. The molding mold 9 is subsequently cooled rapidly eventually at the solidification temperature, and after the mold has been opened, the molding is released from the mold. Moldable preforms 1 are laminated and contoured to bear a three-dimensional shape through the respective steps. |
