Although pitch-based carbon fibers can be melt spun, the flow characteristics of mesophase pitch make it extremely difficult to process. Mesophase pitch, like many fluids, can be non-Newtonian, but its viscosity is considerably more temperature sensitive than most melt-spun materials. In the present

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