Abstract
Provided is a method for manufacturing a fiber reinforced resin molded article capable of effectively increasing the strength of a fiber reinforced resin molded article, such as a high-pressure tank, and such a manufacturing device thereof. With use of a cutting core that is heated to a higher temperature than a mold, the curing of a portion of resin (thermosetting resin) to be cut in a runner is facilitated, and the portion of the resin to be cut in the runner is cut by the cutting core. The heating temperature of the cutting core is higher than the temperature of the mold and lower than the heating temperature in an aftercure step performed after removing the high-pressure tank from the mold.
