PURPOSE:To prevent the generation of wrinkles on a prepreg laminate by impregnating the base material of a laminate with resin to obtain a prepreg material and laminating this prepreg material in a plane shape and placing this laminated material on a curved-face laminating mold, heating and pressurizing it in a vacuum state to cure it. CONSTITUTION:A plurality of sheets of prepreg material 11 are laminated on a planar laminating mold 10 via a laminating machine 1. The prepreg material 11 wherein the base material of a laminate is impregnated with resin is made by cutting this impregnated base material in a plane shape so that the curved-face shape to be molded is made a nearly developed shape. When the laminated laminate 12 is made a prescribed shape, it is placed on a curved-face laminating mold 3 and the whole body is covered with a vacuum bag 13 and the inner space 14 is held in a vacuum state. Firstly the shape of the laminate 12 is molded into the shape along the surface of the curved-face laminating mold 3 by making the inner space 14 a vacuum state. Then this molded laminate 12 is heated, pressurized and cured. Thereby the prepreg laminate having a curved face is molded. |
