Abstract
Oxidation resistant coatings on carbon fibers are provided. Oxidation inhibitor particles are incorporated into a polymeric sizing coating on carbon fibers to protect the fibers from deterioration and erosion due to oxidation of carbon.
Claims40
A method of incorporating oxidation inhibitor particles into a polymeric sizing coating on carbon fibers, comprising contacting said fibers with a uniform suspension of submicron particles of at least one oxidation inhibitor in a sizing solution, removing said fibers from said sizing solution, and removing the residual solvent, whereby an oxidation resistant coating comprising a uniform dispersion of said submicron particles is formed on the surface of said carbon fibers.
Oxidation resistant coating on the surface of a carbon fiber comprising a uniform dispersion of submicron particles of at least one oxidation inhibitor in a polymeric layer.
Oxidation resistant carbon fiber comprising a polymeric coating deposited on the surface of said fiber, said coating containing a uniform dispersion of submicron particles of at least one oxidation inhibitor.
