This study investigates the oxidation mechanisms of carbon-carbon composite materials of the type used for aircraft brakes. The rate-controlling steps for oxidation at temperatures ranging between 450 and 750ยฐC were determined by measuring activation energies of composite samples in bulk form and in

โฆ Synopsis
The work-of-fracture (ywOF) of carbon-carbon composites was measured for composites with 3-D woven fiber preforms, carbon felts, and chopped fibers. Maximum values were observed for the 3-D preforms and minimum values for the carbon felts. The values are also compared with similar data for graphites and glassy carbon.
