  • Publication number: 20210229377
    Abstract: An aircraft structure (such as a T-shaped structure, a convex structure, a curved structure, or the like) includes: a laminated structure including composite-material layers that are laminated; and wherein the composite material aircraft structure is a three-dimensional structure that includes at least one of a standing structure, a convex structure, or a curved structure. The composite-material layers include at least a composite-material layer in which a reinforced fiber is a single continuous fiber, wherein the single continuous fiber includes a partial slit region. When a thickness of a flat-plate formed body including a same laminated structure as the aircraft structure but not including the three-dimensional structure, is defined as a reference thickness, the aircraft structure includes a thin plate region which has a thickness that is smaller than the reference thickness while maintaining the laminated structure.

  • Patent number: 8316683
    Abstract: A product intermittently having a bent portion which curves three-dimensionally and a quenched portion is manufactured by performing bending downstream of a support means while feeding a metal material which is supported by the support means from an upstream side towards a downstream side. A portion of the metal material is heated by a heating means downstream of the support means. A bending moment is imparted to the portion of the metal material heated by the heating means to three-dimensionally change the position of a movable roller die which is disposed downstream of the heating means and has a plurality of rolls which feed the heated metal material in the axial direction, and the metal material is quenched by spraying a cooling medium at the portion of the metal material which was heated by a cooling means disposed between the heating means and the movable roller die.
