A manufacturing apparatus and manufacturing method of a preform to be used for RTM forming, and preform manufactured by the method, wherein a layered body consisting of a plurality of layered reinforcing-fiber base materials to which a fixing agent consisting primarily of a thermoplastic resin is attached is formed into a predetermined shape as heated in a forming mold consisting of molds facing to each other, characterized in that only the first mold is provided with a heating mechanism and a contact face of the second mold contacting the reinforcing-fiber base material is made of a material which is less thermally conductive than the first mold. Provided is manufacturing apparatus and manufacturing method of preform, and preform manufactured by the method, wherein the energy saving can be achieved with low heat dissipation and high heating efficiency, and even a preform formed into a complicated shape can surely and easily be manufactured to be used for RTM (Resin Transfer Molding) forming method with a high dimension accuracy. |
