CONTRIBUTION OF OXIDATION TO THE WEAR OF CARBON-CARBON COMPOSITES

An investigation was made on composites for aircraft brake materials. Wear rate increased with increasing oxygen partial pressure; the wear in air was more than 4.5 times the wear in an inert atmosphere. At least 60% of the total weight loss was caused by oxidation, that is, direct removal by conversion of the solid to CO and CO2. Oxidation weakened the surface and subsurface, which in turn facilitated material removal by mechanical action at the rubbing interfaces.
