Abstract
The present invention provides an oven range. In the present invention, a method for coating an oxidation protective layer for a carbon/carbon composite, comprising: dissolving a polymer resin in a solvent to form a solution of polymer resin; dispersing ceramic powders in the solution of polymer resin to form a mixed solution; coating the mixed solution on a carbon fiber; performing a first heat-treatment to treat the carbon fiber by heat in air; and performing a second heat-treatment to treat the carbon fiber by heat under an inert gas.
