MANUFACTURING METHOD FOR ARTICLE MOLDED FROM FIBER-REINFORCED COMPOSITE MATERIAL, AND ARTICLE MOLDED FROM FIBER-REINFORCED COMPOSITE MATERIAL

摘要

A manufacturing method for a molded article of a fiber-reinforced composite material obtains a molded article of a fiber-reinforced composite material having a three-dimensional shape by: preparing a sheet-shaped prepreg containing reinforcing fibers and a matrix resin composition; preliminarily shaping the prepreg to produce a plurality of partial preforms having shapes obtained by dividing the shape of the molded article; producing a first partial preform group and a second partial preform group, which have the shape of the molded article, by combining the plurality of partial preforms so that the ends thereof in the direction perpendicular to the thickness direction do not overlap in the thickness direction; producing a preform by bringing the first and second partial preform groups into close contact with each other in the thickness direction; and compression molding the preform using a molding die.
