Abstract

Bromination was found to increase the oxidation resistance of Thornel P-100 pitch-based carbon fibers in the temperature range from 675 to 925°C, whereas it decreased the oxidation resistance of P-X-7 pitch-based carbon fibers. The increased oxidation resistance may be due to bromine adsorption or the electron transfer from the graphite to the bromine. However, the pronounced intercalation in brominated P-X-7 (which is more graphitic than P-100) probably causes physical damage which decreases the oxidation resistance.
