Claims
- 1. A hybrid structure comprising a corrosible metal in contact with conductive fibers of an electrical conductive fiber reinforced polymer matrix composite, wherein the composite has incorporated therein an amount of an inorganic inhibitor effective to reduce the current density measured in a degraded zone of the matrix composite, as measured on test specimens after 625 hours of exposure in accordance with ASTM B-117 (1979).
- 2. The hybrid structure of claim 1, wherein the inorganic inhibitor is incorporated into the composite in an amount of from 0.5 to about 10 weight percent based on the weight of the polymer matrix.
- 3. The hybrid structure of claim 1, wherein the inorganic inhibitor is a cathodic inhibitor.
- 4. The hybrid structure of claim 1, wherein the inorganic inhibitor comprises one or more compounds selected from the group consisting of zinc phosphates, calcium strontium zinc phosphosilicates, calcium molybdates, silver salts and silver oxides.
- 5. The hybrid structure of claim 1, wherein the polymer matrix of the conductive fiber reinforced matrix composite is a degradable polymer matrix.
