Document Type and Number:
Japanese Patent JP2021102274
Kind Code:
A
Abstract:
To provide a method for obtaining a fiber reinforced resin molded product with high dimensional accuracy by press-molding a thermoplastic fiber reinforced resin.SOLUTION: A method for manufacturing a thermoplastic fiber reinforced resin molded product with a thickness of 0.2 to 5.0 mm by pressing one prepreg 3 of a thermoplastic fiber reinforced resin, a plurality of laminated prepregs, or a plurality of prepregs laminated by arranging an adhesive or an adhesive resin sheet between the prepregs includes: a step of raising temperatures of an upper mold 1 and a lower mold 4 to 170 to 270°C; a step of arranging the prepreg between the upper mold and the lower mold; a step of deforming the prepreg by applying a load to the prepreg; a step of lowering the temperatures of the upper mold and the lower mold at a rate of 5 to 50°C per minute; and a step of raising the temperature of the upper mold and taking out the thermoplastic fiber reinforced resin molded product after the upper mold and the lower mold are sufficiently cooled.SELECTED DRAWING: Figure 1
