EFFECTS OF INHIBITOR CONTENT ON OXIDATION RESISTANCE OF C/C COMPOSITES

The effects of borax glass inhibitor content on oxidation resistance of C/C composites was studied by oxidation experiments. The oxidation mechanism was analyzed on the basis of SEM results. The results showed that the porosity of C/C composites decreased with the increasing of inhibitor content together with the increasing of oxidation resistance. Saturation stage of oxidation resistance was reached with the inhibitor content over 9.0wt%. The oxidation resistance osf C/C composites has been greatly improved with the filled inhibitor.
