  • Reducing galvanic degradation of hybrid metal/composite structures
    Patent number: 5871839
    Abstract: Galvanic degradation under salt spray or salt water conditions in hybrid structures containing a corrosible metal and a conductive fiber reinforced polymer matrix composite is reduced through the addition to the polymer matrix of the composite of an effective amount of an inorganic corrosion/degradation inhibitor.
    Type: Grant
    Filed: June 13, 1997
    Date of Patent: February 16, 1999
    Assignee: CYTEC Technology Corporation
    Inventors: Jack D. Boyd, Lawrence C. Hopper
