AN INVESTIGATION OF OXIDATION PROTECTION FOR C/C COMPOSITE BRAKING MATERIAL

Yang Zun

Abstract

Compositions of the coating material included metal phosphates,phosphoric acid, boric acid, phosphatic modifier and acid soluble metal oxide etc. C/C composite braking material samples were coated with a sol gel process using the material above mentioned. Thermal shock and air oxidation test at high temperature were performed for the coating C/C samples.The results showed that modified phosphatic coating layer could effectively inhibited oxidation of C/C composite braking material at simulated aircraft stopping factors.Raw and processed material of the coating are inexpensive and technological process is simple and convenient.
