Abstract
An object is to provide a fiber-reinforced molded product that is superior in terms of lightness, thinness and high rigidity. A fiber-reinforced molded product has a core material 11 and a fiber-reinforced material 21 provided on both surfaces of the core material 11. The core material 11 is formed by impregnating a thermosetting resin foam having open cells with a first thermosetting resin and curing the thermosetting resin while compressing the impregnated thermosetting resin foam with a compression rate of 200 to 5000. The fiber-reinforced material 21 is formed by impregnating a carbon fiber fabric with a second thermosetting resin and curing the second thermosetting resin. A resin ratio of the first and second thermosetting resins after the impregnation is 50 to 80. The core material 11 and the fiber-reinforced material 21 are formed as a unitary body by curing the first and second thermosetting resins.
