Abstract

In a method for producing a fiber-reinforced resin molded body () by heat-compressing fiber substrates (A toD) together with a thermosetting resin () so that the thermosetting resin () is impregnated into the fiber substrates (A toD) and cured, a thermosetting resin powder (A) is disposed in contact with at least one surface of the fiber substrates (A toD), the fiber substrates (A toD) are heat-compressed together with the thermosetting resin powder (A) by a mold () so that the thermosetting resin powder (A) is melted, impregnated into the fiber substrates (A toD), and cured. Also disclosed is a fiber-reinforced resin molded body as well as a vehicle or airframe including a fiber-reinforced resin molded body.
