Abstract:
1. A fiber-reinforced molded product, comprising: a core material; a fiber reinforcing material laminated on at least one surface of the core material; and a surface material laminated on the fiber reinforcing material, the core material is formed by curing a thermosetting resin which is impregnated into a core material member in a compressed state, the core material member being a resin foam having open cells, the fiber reinforcing material comprises a fiber fabric and a thermosetting resin impregnated into the fiber fabric and cured, wherein the core material, the fiber reinforcing material and the surface material are integrated by the thermosetting resin, the surface material comprises an urethane resin foam sheet, from which cell membranes are removed, and the urethane resin foam sheet is laminated on the fiber fabric and the resin foam and heated in a compressed state such that the thermosetting resin which is impregnated in at least one of the core material member and the fiber fabric before curing is impregnated into the urethane resin foam sheet and cured, so that the thermosetting resin extruded on a surface of the urethane resin foam sheet, from which cell membranes are removed, is cured on the surface material has a surface roughness Rz of 30 μm or less, and a thickness ratio of the urethane resin foam sheet to the core material is from 4% to 30% before compression.
