✦ Synopsis

Bromination was found to increase the oxidation resistance of Thornel P-100 pitch-based carbon fibers in the temperature range from 675 to 925Β°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.

Oxidation behaviour of a variety of carbon fibers made from isotropic as well as mesophase pitch has been studied. The microstructure of these carbon fibers has been studied using SEM Optical Microscope. and x-ray diffractometer. After graphitization, the carbon fibers made from isotropic pitch did
