  • Fabric for fiber reinforced composite material and fiber reinforced composite material
    Patent number: 10947647
    Abstract: A fabric laminate used as a reinforcing base material of a fiber-reinforced composite is constituted by laminating fabrics having warp yarns and weft yarns. Each warp yarn has a diameter-changing portion, in which the diameter of the yarn gradually changes in the yarn longitudinal direction in the vicinity of one end in the yarn longitudinal direction of the warp yarn.
    Type: Grant
    Filed: December 8, 2016
    Date of Patent: March 16, 2021
    Assignee: KABUSHIKI KAISHA TOYOTA JIDOSHOKKI
    Inventors: Genki Yoshikawa, Ryuta Kamiya, Shun Kuno
  • Fiber wound body, fiber-reinforced resin material, and method for manufacturing fiber wound body
    Patent number: 10767022
    Abstract: This fiber wound body has a plurality of reinforcing fiber yarns wound around a winding axis, each of the reinforcing fiber yarns having a thickness gradient portion in which the fiber content is uniform along the longitudinal direction of the yarn and the thickness gradually changes.
    Type: Grant

  • Fiber-reinforced composite material
    Patent number: 9302445
    Abstract: A fiber-reinforced composite material (11) is constructed by laminating a plurality of fiber bundle layers formed of a reinforced fiber to form a laminated fiber bundle layer and further impregnating the laminated fiber bundle layer with a matrix. At either side of a neutral surface (16), the number of +? layers which are fiber bundle layers having a fiber orientation angle of +? and the number of ?? layers which are fiber bundle layers having a fiber orientation angle of ?? are the same, the order of laminating the fiber bundle layers is inversely symmetrical with respect to the standard surface, and the number of other fiber bundle layers disposed between the +? and ?? layers at either side of the standard surface is the same.
