Amod A. Ogale 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).

  • Mesophase pitch-based carbon fibers with carbon nanotube reinforcements
    Patent number: 7153452
    Abstract: A modified, mesophase pitch-based carbon fiber is disclosed which includes carbon nanotube reinforcements in an amount ranging from about 0.01 percent to about 1.0 percent by weight. Although the reinforcements actually decrease the excellent tensile modulus of the unmodified fiber, they provide a random microstructure, which can decrease brittle failure of the fiber caused by propagation of a flaw.
    Type: Grant
    Filed: September 12, 2003
    Date of Patent: December 26, 2006
    Assignee: Clemson University
    Inventors: Amod A. Ogale, Dan D Edie, Apparao M. Rao
