Abstract

Abstract: SEM, X-ray Diffraction and Reflected Polarized Micrography using crossed polarizers were employed to investigate the orientation of unidirectional C/C composites matris mesophase pitch in 0.8T magnetic field and verified that the mesophase layers of the C/C composites were parallel to magnetic field s direction. It was found that the mesophase layers of the C/C composites in the magnetic field were perpendicular to the carbon fibers.

Key words: strong magnetic field, C/C composites, mesophase pitch, orientation, SEM
