초록 ▼

A novel structural member, such as a golf club shaft or other tapered tubular member, having an unusually high resistance to torsional deflection for given desired longitudinal deflections along with high strength and a center of gravity more favoring the tip-end is provided by a resin-bonded graphite fiber structure in which the fiber orientations in each layer of the multi-layer, composite structure are varied along the length of the shaft and in desired orientation relationships between layers to achieve the unique combination of properties. This structural member is prepared by helically placing fiber yarns such as graphite onto a resin-coated, tapered steel mandrel by winding a series of high modulus graphite yarns in series of layers and progressively varying the rotational speed of the rings carrying the spools of the graphite fiber yarns in each layer as the mandrel is fed at a constant speed. The continuously varying rotational speeds of these rings and the wrapping angles to which the yarns are applied to the mandrel result in a unique structure achieved by optimizing the wrapping angles in each layer at desired progressive changes in fiber orientation different in each layer, and from layer to layer in the structure.

대표청구항 ▼

An improved tapered tubular golf club shaft having a butt end and tip end and consisting essentially of a series of helically wound layers of graphite fibers bonded with a thermosetting epoxy resin material, said improved shaft comprising a plurality of graphite fiber tows in each layer extending continuously for the entire length of the hollow tubular shaft, the wall thickness of the shaft increasing curvilinearly from the butt to the tip end in a smooth curve from about 0.045 inches to about 0.095 inches, with about two-thirds of the layers forming the inner layers having an orientation of the fiber tows in the range of about 13°to 45°with respect to the longitudinal axis of the tubular shaft, of which there is an even number of such layers and in which the fiber tows in alternate layers are wrapped in opposing clockwise or counterclockwise directions, or counterclockwise and clockwise directions, the angle of the fiber tows in the inner layers decreasing in the specified range from the butt end to the tip end, and about one-third of the layers forming the outer layers having an orientation of the fiber tows of up to 18 degrees with respect to the longitudinal axis of the tubular shaft, the angle of the fiber tows in the outer layers increasing in the specified range from the butt end to the tip end, with such outer layers wrapped in either the clockwise or counterclockwise direction, in which the orientation of the fiber tows varies continuously along the tube length as a result of the taper of shaft in combination with a continuous change in rate of wrapping of the tows in at least either two of the adjacent inner layers having the opposed wrapping direction, 13 to 45 degree fiber orientations or in the outer layers with up to 18 degree fiber orientation.
