A main object of the present invention is to provide beneficial improvements relating to a method for producing a fiber reinforced plastic product, the method including curing while pressurizing a prepreg preform by using a core having a fusible part as means for pressurizing. A method for producing a fiber reinforced plastic product, the method including: a core preparation step of preparing a core comprising a fusible part and an outer skin covering the fusible part; a molding step of disposing a prepreg preform inside a mold together with the core, and heating and pressurizing the prepreg preform in the mold to obtain a cured product; and a core removal step of removing materials of the fusible part from the cured product, in the molding step, at least a portion of the prepreg preform being pressurized by expansion of the core, in which the fusible part comprises a first fusible part and a second fusible part having a fusion temperature higher than that of the first fusible part, a material of the first fusible part and a material of the second fusible part are incompatible with each other, and in the molding step, the first fusible part fuses partially or entirely, while the second fusible part does not fuse partially or entirely.

Provided is a method for manufacturing a fiber reinforced plastic molded body, the method including: performing thermocompression molding, by using a molding die, on a molding precursor which is obtained by arranging a prepreg including a thermosetting resin and a fiber around a thermoplastic solid body.

A wax decal production and application system is disclosed involving a wax sheet, an indentation roller, a method of cutting the wax sheet, and a roller to apply the sheet to a surface. A thin wax sheet is extruded through drums that pattern it with indentations. A design is cut into the sheet and the extraneous material is removed. The wax decal is placed upon a surface. With the use of a roller, the indentations are crushed, collapsing onto and sticking to the surface.
