REVIEW ON OXIDATION KINETICS OF CARBON FIBER/CARBON MATRIX COMPOSITES AT HIGH TEMPERATURE.

Abstract

The papers on the oxidation kinetics are reviewed to clarify the rate-controlling steps and the micromechanisms of oxidative attack. In the first part of the report, the general oxidation behavior of c/c composites is presented and then the detailed discussion is given on the relation of the oxidation rate to total surface area, to gas flow rate, to partial pressure of oxidizing gases and to the mechanical stresses. Finally, the oxidation rate of c/c composites with antioxidation treatments is discussed.
