Provision for Providing Oxidation Protection

Above 370°C, carbon-carbon composites readily oxidize in air, 

Initially, the fiber matrix interface is attacked, resulting in delamination cracking between plies, but as the temperature increases, more severe oxidation attack occurs within the 

Use of inhibitors and sealants to block active sites internally and stifle the rate of oxidation 

Apply a barrier coating to form a protective outside layer, preventing O2 moving inwards and carbon moving out.
