摘要
利用正交偏光可分辨C/C复合材料中不同类型的沉积炭,通过旋转检偏器可测量C/C复合材料中沉积炭的消光角度。列举了偏光观察C/C复合材料实验过程中经常遇到的问题,介绍了测定消光角度的方法,简要概述了近年来研究热解炭各向异性的成果。
Various types of deposited carbon textures can be identified by the appearance under optical microscopy with cross-polars. The extinction angle of the deposited carbon in C/C composite can be measured by rotating the analyzer. The problems encountered during the observation by polarized light microscopy are listed. The method to measure the extinction angle is also introduced. In addition, the recently research results on pyrocarbon anisotropy is briefly presented.
