摘要： 本工作利用扫描电镜、X射线衍射仪及正交偏光显微镜研究了沥青中间相以及单向C／C复合材料基体中间相在800mT磁场中处理后的取向，证实了沥青中间相的层片平行于磁场方向；在本工艺条件下，制造的单向C／C复合材料基体中间相层片垂直于碳纤维.

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.
