Production method for fiber-reinforced resin molded article

A method for producing a fiber-reinforced resin molded article having a thickness from 1.0 mm to 9.0 mm by pressing a single prepreg of a fiber-reinforced resin, a plurality of stacked prepregs or a plurality of stacked prepregs with adhesive resin sheets interposed between the prepregs, the method comprising the steps of:

• positioning the prepreg between a heated upper die and a heated lower die,
• lowering the upper die and applying a load to the prepreg with the upper die and the lower die, wherein the upper die is lowered while temperatures of the upper die and the lower die are further increased to a temperature range from 10° C. lower than a curing starting temperature of a prepreg resin to 20° C. higher than the curing starting temperature of the prepreg resin within 1 minute before or after the upper die is positioned at a bottom dead center,
• maintaining the temperatures of the upper die and the lower die within the temperature range from 10° C. lower than the curing starting temperature of the prepreg resin to 20° C. higher than the curing starting temperature of the prepreg resin for 0.3 to 2 minutes per 1 mm of a thickness of the prepreg while the upper die is positioned at the bottom dead center,
• reducing or stopping the heating of the upper die and the lower die, and
• after reducing or stopping the heating, raising the upper die to extract the fiber-reinforced resin molded article.
