  • Publication number: 20150075663
    Abstract: A pipe includes a tubular reinforced fiber structure, and a tubular matrix resin pipe main body centered on the central axis, together with a reinforced fiber structure, covering an internal side of the reinforced fiber structure on the central axis side, and an external side. An external end surface of the pipe main body has an inclined surface whose diameter is gradually reduced toward the end face, which connects the pipe main body to another pipe main body, with the main body inclined surface coupled to a substantially tubular-shaped coupling. A portion of the reinforced fiber structure near the main body inclined surface has a plurality of fiber bundles extending in parallel to the central axis. This prevents a shear failure of the fiber bundles of the reinforced fiber structure of the main body inclined surface.
