Patents by Inventor Robert Jurek

Robert Jurek 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).

  • Reinforced composite with a tow of fibers and process for the preparation thereof
    Publication number: 20080213498
    Abstract: A graphite coated tow of fibers having exfoliated and pulverized graphite platelets coated on an outer surface of the fibers are provided. A process is provided for surface coating of the graphite platelets onto the fibers. The graphite coated tow of fibers are used to produce a reinforced composite material. Reinforced composite materials incorporating the graphite coated fibers can be electrostatically painted without using a conductive primer on a surface to be painted.
    Type: Application

  • Material and method for the preparation thereof
    Patent number: 6171688
    Abstract: Composite products incorporating a polymer matrix, polymer microspheres, glass microspheres and natural fibers, particularly kenaf and wood fibers, are described. The polymer microspheres are 15 to 50 microns in diameter and are smaller than the glass microspheres which are 50 to 200 microns in diameter. The polymer microspheres reduce voids and prevent cracking of the glass microspheres upon compression. The composites have low cost and high strength.
    Type: Grant

    Date of Patent: January 9, 2001
    Assignee: Board of Trustees operating Michigan State University
    Inventors: James Zheng, Roger J. Morgan, Robert Jurek
