Abstract
A composite shaft having an integral grip. The shaft comprises a plurality of plies of pre-preg composite sheet molded into a tubular shaft body. The shaft body has a grip directly molded on one end which may include a grip geometry and/or an ornamental pattern. To manufacture the shaft, plies of pre-preg may be wrapped around a bladder-covered mandrel in a predetermined manner and placed in a mold. The mold defines a cavity including, if desired, a selected grip geometry and/or ornamental design. The bladder is inflated, forcing the plies of pre-preg against the wall of the mold, and the mold is heated for a selected time to cure the plies. The grip of the shaft may be covered with a light coating material, providing a rubber-like feel.
