  • Patent number: 10688736
    Abstract: A method of molding composite materials including shaping a laminate having fiber sheets laminated over one another, by bending the laminate in an X-direction and a Y-direction, in a three-dimensional orthogonal coordinate system. The method further includes mounting the laminate that has been shaped, onto a mold material deformed in a Z-direction, impregnating a resin material into the laminate while adjusting an amount of the resin material filled in, and molding the composite materials that have cured such that the composite materials are shaped to have a first inclined surface inclined at a first inclination angle with respect to a reference plane in the Z-direction. The mold material has a first inclination molding surface that molds the first inclined surface, and a second inclination molding surface that molds a surface of the composite materials into a second inclined surface having a second inclination angle smaller than the first inclination angle.
