摘要： The invention includes a surface material (21) layered on both surfaces of a honeycomb core (11). The surface material (21) comprises a surface material member (27), which is a porous sheet (25) layered on a carbon fiber body (23), impregnated with a thermosetting resin which is then cured. Thermosetting resin that has exuded from the porous sheet (25) due to the honeycomb core (11) biting into the resin porous sheet (25) is cured at the position where the porous sheet (25) abuts the honeycomb core (11).

摘要： An object is to provide a highly rigid fiber-reinforced resin molded body in which a thermosetting resin is cured in a fiber substrate easily, inexpensively, and safely with less environmental pollution without using a prepreg.
In a method for producing a fiber-reinforced resin molded body (10) by heat-compressing fiber substrates (11A to 11D) together with a thermosetting resin (15) so that the thermosetting resin (15) is impregnated into the fiber substrates (11A to 11D) and cured, a thermosetting resin powder (15A) is disposed in contact with at least one surface of the fiber substrates (11A to 11D), the fiber substrates (11A to 11D) are heat-compressed together with the thermosetting resin powder (15A) by a mold (30) so that the thermosetting resin powder (15A) is melted, impregnated into the fiber substrates (11A to 11D), and cured.
