  • Golf club shaft with variable density tip plug
    Patent number: 6797208
    Abstract: A golf club and a primarily non-metallic golf shaft that has an overall light weight are provided. The shaft has a weighting plug located to provide a swingweight similar to a typical steel shafted golf club. A method of making the golf club and golf shaft is simple and efficient, and centers the plug in the golf shaft. The method also provides the advantage of substantially infinitely variable plug density selection within a range of densities. A set of clubs thus made increases playability by providing a range of club weights in the set.
    Type: Grant

  • Article and method for making complex shaped preform and silicon carbide composite by melt infiltration
    Patent number: 6258737
    Abstract: Small diameter silicon carbide-containing fibers are provided in a bundle such as a fiber tow that can be formed into a structure where the radii of curvature is not limited to 10-20 inches. An aspect of this invention is directed to impregnating the bundles of fibers with the slurry composition to substantially coat the outside surface of an individual fiber within the bundle and to form a complex shaped preform with a mass of continuous fibers.
