Method for producing fiber-reinforced plastic molding, preform and method for producing same, and adhesive film |
摘要 |
The present invention is a method for producing a fiber-reinforced plastic molding including, in the following order, the steps of: forming a preform laminate fixed to a molding die by laminating a plurality of preforms each including a dry fiber fabric and a fixing resin, the preforms being laminated through the fixing resin formed on a surface of the dry fiber fabric and including a partially-cured thermosetting resin exhibiting tackiness at a room temperature; impregnating the dry fiber fabric, provided in the preform laminate fixed to the molding die, with a liquid thermosetting resin; curing the liquid thermosetting resin and the fixing resin to form a fiber-reinforced plastic molding; and demolding the fiber-reinforced plastic molding from the molding die. |

1. A method for producing a fiber-reinforced plastic molding, comprising, in cited order, the following:
mixing vinyl ester resin having both of a (meta-) acryloyl group and an epoxy group in a resin skeleton, an epoxy curing agent, and organic peroxide to prepare a partially-cured vinyl ester resin with said epoxy group reacted solely; forming a preform laminate by laminating a plurality of preforms each including a dry fiber fabric and a fixing resin, the preforms being laminated through said fixing resin, said fixing resin being formed in a dot pattern on a surface of the dry fiber fabric and being said partially-cured vinyl ester resin; fixing the formed preform laminate to a molding die via the fixing resin of one of the preforms; impregnating said dry fiber fabric, provided in said preform laminate fixed to said molding die, with a liquid vinyl ester resin; curing said liquid vinyl ester resin and said fixing resin at the same time to form a fiber-reinforced plastic molding; and demolding said fiber-reinforced plastic molding from said molding die. |
