Latest Patents

Among his latest patents is the "Rotating ring structure for gas turbine engines and method for its manufacture." This invention involves creating a composite jet engine compressor ring by casting a tape reinforced with ceramic fibers. The process includes winding the cast tape around a mandrel to form an unconsolidated ring, heating it to drive off the binder, and pressing it at high temperatures to create a unitary composite ring. The axial compression during hot pressing achieves the desired spacing between adjacent fibers. The tape is preferably cast from a mixture of titanium base metal particles and a polyisobutylene binder dissolved in an organic solvent. Another significant patent is the "Tape casting fiber reinforced composite structures." This invention describes a fiber reinforced composite tape made by casting a mixture of high-temperature metal or intermetallic particles, continuous ceramic fibers, and a polymeric binder. The preferred particles are titanium alloy or titanium aluminide with a top size greater than 50 microns, and the binder is typically polyisobutylene. The cast composite tape is combined with other tapes, heated in a vacuum to remove the binder, and pressed at elevated temperatures and pressures to form a composite structure suitable for high-temperature applications.
