  • FIRE-RESISTANT STRUCTURAL COMPOSITE MATERIAL
    Publication number: 20070276074
    Abstract: Fire-resistant structural composites are comprised of a phenolic resin system, reinforcing fibers and alumina tri-hydrate. The composites may be formed into structural or load-bearing parts, and are particularly suited for applications requiring high strength and a high degree of fire-resistance, such as in the automotive, aircraft, or ship-building industry. Optionally, a siloxane modifier may be added to the resin system to improve the flexibility and impact resistance of the composite.
    Type: Application

  • Composite motor end housing with a metallic sleeve bearing support
    Patent number: 6150743
    Abstract: An electric motor housing including a metal internal hub and composite material reduces weight, reduces motor vibration transmission, increases mechanical damping, improves corrosion resistance and improves electrical performance.
    Type: Grant
    Filed: April 24, 1997
    Date of Patent: November 21, 2000
    Assignee: Electric Boat Corporation
    Inventors: Piet Van Dine, Vladimir Odessky, Brian E. Spencer, James S. Smith, William R. Harring
  • Method for making a composite electric motor housing
    Patent number: 6125528
    Abstract: An electric motor housing is made by press-forming a composite material on a metal cylinder and machining passages in the press-formed material. This reduces weight, reduces motor vibration transmission, increases mechanical damping, improves corrosion resistance and improves electrical performance.
    Type: Grant
