Patents by Inventor Daniel H. Hecht

Daniel H. Hecht 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).

  • Fiber-reinforced carbon and graphite articles and method for the production thereof
    Patent number: 5654059
    Abstract: The present invention relates to the fabrication of thick, three-dimensional structures comprising discontinuous thermoset pitch fiber, and to composites comprising such structures embedded in a matrix material such as a thermoset resin, ceramic, metal or carbon. Carbon-carbon fiber composite articles produced from porous carbon preforms obtained by carbonizing such structures followed by infiltration with pyrolytic carbon using CVD processes exhibit surprisingly high through-thickness thermal conductivity and isotropic properties.

  • Method for the preparation of high modulus carbon and graphite articles
    Patent number: 5552008
    Abstract: Self-reinforcing, pitch-based carbon articles having an unique combination of excellent thermal conductivity and outstanding mechanical properties are produced by carbonizing acid-treated mesophase pitch fiber, preferably in the form of a preform structure. The carbon articles having varying degrees of porosity are particularly desirable for use in thermal management and stiffness applications, and in carbon vapor infiltration processes employed in making complex solid carbon articles.
