Patents by Inventor Thomas E. Burghardt

Thomas E. Burghardt 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).

  • Patent number: 9957378
    Abstract: Various methods and systems of making inorganic fiber/flake reinforced composites having a thermoplastic matrix are disclosed. The methods use systems similar to those used to make inorganic fiber/flake reinforced products having a thermoset matrix, but the systems and methods are modified to use thermoplastic precursor monomer(s) followed by in situ polymerization of the monomer(s) during and/or following forming of the desired shape of the products. These methods permit the manufacture of superior inorganic fiber reinforced thermoplastic matrix composites in large and very large shapes heretofore not possible, or practical.
    Type: Grant

  • Publication number: 20170081799
    Abstract: A surface-modified fibrous material is provided for incorporation in a thermoplastic matrix to form a fiber-reinforced composite article. Good binding between the fibrous material and the thermoplastic matrix is achieved through the presence of finely roughened surfaces on the fibers of nanoparticles of an inorganic material. Such nanoparticles are provided from an alkaline aqueous size composition containing the nanoparticles dispersed therein (as described). The fibrous material may be provided in continuous or discontinuous form. In a preferred embodiment glass fibers are initially provided in continuous form followed by cutting into discontinuous lengths and drying with the retention of the nanoparticles on the surfaces of the fibers. The surface-roughened fibrous material is incorporated in a thermoplastic matrix as fibrous reinforcement with the application of heat whereby the thermoplastic matrix is rendered melt processable. In preferred embodiments injection or compression molding is utilized.

  • Publication number: 20100196697
    Abstract: Reinforcing fibers with small particles having a longest average dimension of approximately 0.01 nanometer to approximately 30 micrometers physically and/or chemically bonded directly to their surfaces to form protuberances thereon and a method and system for making these modified fibers are disclosed. The particles directly bonded to the surfaces of the fibers, serve to enhance physical properties of composite articles which incorporate such fibers as reinforcement.
