  • Structural member of pipe shape
    Patent number: 5348777
    Abstract: The present invention provides a pipe-shaped structural member made of fiber reinforced plastics or fiber reinforced rubber utilizing the mechanical property of the material as an anisotropic material. Since the angle of the fibers and/or direction of orientation are made partially different in the circumferential direction of the structural member, and moreover, since the part where the angle of fibers and/or direction of orientation are made partially different is at least a part in the thicknesswise direction of the circumferential part, the pipe-shaped structural member shows a peculiar style of deformation, and is applicable to a variety of industrial fields.
    Type: Grant
    Filed: April 29, 1993
    Date of Patent: September 20, 1994
    Assignee: Sumitomo Rubber Industries, Ltd.
    Inventors: Masahide Oonuki, Tetsuo Yamaguchi, Akihiro Nakahara, Mitsunori Miki
