WIPO Patent Application WO/2005/065785
Kind Code:
A1
Abstract:
A fiber-reinforced resin golf shaft formed by laminating a plurality of fiber-reinforced resin layers, wherein the fiber-reinforced resin layers comprise tetraxial fabric layers formed by reinforcing tetraxial fabric with a molding resin. The tetraxial fabric is formed of a plurality of vertical axis yarns extending parallel with the longitudinal direction of the shaft, a plurality of lateral axis yarns extending along a direction orthogonal to the longitudinal direction of the shaft, and one set of a plurality of oblique axis yarns obliquely crossing with each other bilaterally with respect to the longitudinal direction of the shaft. At least one type of the axis yarns of the vertical axis yarns, lateral axis yarns, and oblique axis yarns are formed of fiber-reinforced fibers having characteristics different from those of the other axis yarns.
