Patent ID: 8628842

Claim:
A fiber-reinforced molded product comprising a core material and a fiber-reinforced material layered on both surfaces of the core material, wherein the core material is formed by impregnating a thermosetting resin foam having open cells with a thermosetting resin, and curing the thermosetting resin while compressing the thermosetting resin foam, wherein a compression rate defined by the formula (A1) below is in a range of 200 to 5000% the fiber-reinforced material is formed by impregnating a carbon fiber fabric with a thermosetting resin and curing the thermosetting resin, a resin ratio, defined by the formula (B1) below, of the thermosetting resins with which the thermosetting resin foam and the carbon fiber fabric are impregnated is in a range of 50 to 80%, the core material and the fiber-reinforced material are formed as a unitary body by the curing of the thermosetting resin with which the thermosetting resin foam is impregnated and the thermosetting resin with which the fiber-reinforced material is impregnated, and a flexural modulus of the fiber-reinforced molded product is 30 GPa to 60 GPa: (A1) compression rate={(thickness of thermosetting resin foam before compressing −thickness of core material)/thickness of core material}×100; and (B1) resin ratio={(total weight of thermosetting resin foam and carbon fiber fabric after impregnating with thermosetting resins−total weight of thermosetting resin foam and carbon fiber fabric before impregnating with thermosetting resins)/total weight of thermosetting resin foam and carbon fiber fabric after impregnating with thermosetting resins}×100, and further wherein the fiber-reinforced molded product has a specific gravity of 1.2 to 1.5 and a thickness of 0.3 mm to 2.0 mm.
