Sylvie Bonnamy 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 making a three-dimensional fiber structure of refractory fibers
    Patent number: 7384663
    Abstract: Carbon nanotubes are incorporated in the fiber structure by growing them on the refractory fibers of the substrate so as to obtain a three-dimensional substrate made of refractory fibers and enriched in carbon nanotubes. The substrate is densified with a matrix to form a part of composite material such as a friction part of C/C composite material.
    Type: Grant
    Filed: March 10, 2005
    Date of Patent: June 10, 2008
    Assignee: Snecma Propulsion Solide
    Inventors: Pierre Olry, Yannick Claude Breton, Sylvie Bonnamy, Nathalie Nicolaus, Christian Robin-Brosse, Eric Sion
