  • Reinforcement for rubber composites
    Patent number: 6959534
    Abstract: A method for constructing an elastomeric composite ply comprises using parallel S and Z twisted cords to reinforce an elastomeric matrix. The S and Z cords are made inexpensively by using a yarn twist that is less than the cord twist. Composite plies made by the method can be used in elastomeric articles such as tires.
    Type: Grant

    Date of Patent: November 1, 2005
    Assignee: The Goodyear Tire & Rubber Company
    Inventors: Walter Kevin Westgate, James Cletus Sykora
  • Tire with PEN reinforcement
    Patent number: 6634399
    Abstract: High modulus reinforcement is used to make a radial ply pneumatic tire having only one carcass ply, i.e. a monoply tire. Poly-ethylene naphthalate (PEN) reinforcement is prepared in a manner that provides sufficient strength whereby the monoply tire can be made having reduced weight (as compared to a two ply tire) while having comparable durability, some improved handling, reduced rolling resistance, and improved flatspotting properties.
