  • Carbon-matrix composites, compositions and methods related thereto
    Patent number: 6638883
    Abstract: The present invention relates to carbon-matrix composites, such as carbon—carbon composites, and a method for forming them by forming a fabric of fusible and infusible fibers which can be processed and carbonized to form a composite. The methods disclosed herein permit preparation of composites which are particularly thin, uniform, and highly pure. The invention also relates to preprocessed fabrics and precarbonized composites, such as those comprising carbon or oxidized polyacrylonitrile fibers and fusible polyacrylonitrile fibers.

  • Method of making a composite material
    Patent number: 5364571
    Abstract: Net shape composite articles are made by a molding process. The molded preform is densified in a process where the rate of temperature increase is controlled to prevent distortion. The densified composite objects are impregnated with a secondary material to provide desirable properties such as strength, stiffness, or oxidation resistance. Diverse parts such as golf clubs and engine parts can be made by the process.
