MANUFACTURING METHOD FOR MOLDED ARTICLE OF FIBER-REINFORCED COMPOSITE MATERIAL AND MOLDED ARTICLE OF FIBER-REINFORCED COMPOSITE MATERIALS

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.

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