James E. Shoffner has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method of forming carbon composites
    Patent number: 4193828
    Abstract: The ablative response at predetermined locations in a carbon-carbon reinforced composite material are selectively modified by one or more implants of a compatible, non-carbon material disposed at selected sites in the material. The implants of non-carbon material, which should have a melting point below the sublimation temperature of the surrounding carbon matrix and thermal expansibility having a force below the strength of the surrounding carbon matrix, preferably are arranged essentially parallel to one another at selected axial sites in the direction of expected thermal flux.
    Type: Grant
    Filed: June 12, 1978
    Date of Patent: March 18, 1980
    Assignee: Fiber Materials, Inc.
    Inventors: Peter R. Moores, James E. Shoffner
