Latest Patents
MacLeane's latest patents focus on methods for mass-producing composite shafts. One patent describes a method for joining a composite material shaft, such as a graphite epoxy or fiberglass driveshaft, to a metal end member. This joint is designed to withstand large ranges of temperature and humidity, handle high torque, and exhibit high resistance to fatigue. The innovative design features parallel grooves on the end of a metallic sleeve that is concentrically aligned within the shaft, making it suitable for mass production. The first layer of fibers in the composite material shaft is wound perpendicular to the orientation of the grooves. Additionally, a scalloped pattern carved on the other end of the metallic sleeve facilitates concentric alignment on the tooling mandrel and reduces shear stress between the sleeve and shaft. Another patent details an apparatus for mechanically joining composite shafts to metallic end members, employing an elongated spinning mandrel and pre-preg tape wound at high speed.
