bromination was found to increase the oxidation resistance of thornel p-100 pitch-based carbon fibers in the temperature range from 675 to 925 $degree$ 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.
