FIBER-REINFORCED COMPOSITE MATERIAL MOLDING AND MANUFACTURING METHOD THEREFOR |
摘要 |
The present invention relates to a method for manufacturing a fiber-reinforced composite material molding, having a step (A) for forming a plurality of partial preforms, each having a partial shape obtained by dividing the three-dimensional shape of a target fiber-reinforced composite material molding, by cutting a prepreg sheet containing reinforcing fibers and a matrix resin composition, and by preshaping the cut prepreg pieces; a step (B) for forming a preform having the three-dimensional shape of the target fiber-reinforced composite material molding by combining and integrating the plurality of partial preforms; and a step (C) for producing a fiber-reinforced composite material molding by compression-molding the preform, wherein the step (B) includes arranging a foamable material between the plurality of partial preforms when they are combined. |
