  • Patent number: 9919473
    Abstract: First and second composite members each containing first discontinuous fibers of fiber length La, are placed such that end surfaces thereof face each other at an interval of first length L1. Ends of the first and second composite members are melted over a second length L2 from the end surfaces. A connecting member containing second discontinuous fibers of fiber length Lb, is melted and placed to bridge a space between the ends, to form a stack. The stack is pressed, whereby the melted connecting member and the melted end portions flow into the space between the end surfaces to form a mixture portion. The mixture portion is cooled and solidified to produce a fiber-reinforced resin bonded body. The first length L1 is equal to or more than ½ of the fiber length Lb, and the second length L2 is equal to or more than the fiber length La.

  • Patent number: 9314990
    Abstract: Linking parts are formed on one end of a first resin composite member and on one end of a second resin composite member in order to bond the ends together. For example, the linking parts may be wavy parts containing concave portions and convex portions. In this case, the wavy parts initially are heated and softened. Then, in a molding unit, respective pairs of confronting convex portions are overlapped with each other, and respective pairs of confronting concave portions are utilized to form a non-overlapping space. The overlapped convex portions are pressed and crushed, such that a base thermoplastic resin and fibers contained therein flow toward the non-overlapping space. Thereafter, the thermoplastic resin is cooled and hardened, whereby the first resin composite member and the second resin composite member are bonded integrally to obtain a resin composite structure.

  • Patent number: 9297719
    Abstract: A flight control system loading test apparatus includes a surface-mounted sector, a cam profile sector, a dummy weight, and a cable. The surface-mounted sector attaches to an aircraft flight control system body such that the surface-mounted sector pivots along with the body about a pivot axis. The cam profile sector is configured to rotate about a rotational axis among a plurality of loading positions. The cam profile sector includes a profile surface having a plurality of curves. Each curve follows a different radius emanating from a respective axis substantially parallel to the rotational axis of the cam profile sector. The cable contacts the cam profile sector along the profile surface. An applied hinge moment using the dummy weight varies as the cam profile sector rotates about the rotational axis.
