PROBLEM TO BE SOLVED: To provide a manufacturing method for obtaining an entirely uniform fiber reinforced resin composite body without a deviation of a fiber reinforced material that is being molded in reaction injection molding. SOLUTION: A manufacturing method for obtaining a fiber reinforced composite body comprising the steps of accommodating one or a plurality of mat-like reinforcing fibers and one or a plurality of mat- or net-like bodies that have a resin permeability higher than that of the mat-like reinforcing fibers in a reaction injection molding die 51 in a laminated fashion, closing the die 51, and injecting a reactive raw resin into the die 51, wherein the thickness of the laminated piece is greater than the depth of a cavity of the die 51 when it is closed, and wherein the modulus of elasticity in compression in the thickness direction of the mat-like body 55 or the net-like body 53 ranges from 0.4 to 8.0kgf/cm<2> . |
