Abstract:
A method of protecting a carbon fiber or carbon-carbon (Câ€”C) composite component of approximately 3-30 mils thickness against oxidation, the method comprising the steps of:applying a coating of fluidized glass precursor over, without impregnating, the component by immersing the Câ€”C component in a bath containing glass precursors; gradually heating the precursor-coated component to a temperature range at which glass transition temperature of the glass will be thermally matched to the oxidation temperature of the carbon in the Câ€”C component; and gradually cooling the glass-coated component to envelope the Câ€”C component in a solid glass coating, without the solid glass coating impregnating the Câ€”C component.
