The microstructure of carbon/carbon composites obtained by chemical vapor infiltration of carbon‐fiber felts was studied comparatively by means of Raman spectroscopy, polarized light microscopy (PLM), scanning electron microscopy (SEM), and X‐ray diffraction. The matrices, which are homogeneously textured according to PLM, exhibit pronounced spatial structural gradients at the sub‐μm scale if investigated by means of Raman microprobe spectrometry. The Raman and SEM observations demonstrate that the high‐temperature treatment correlates with the increasing development of the graphitic ordering in low‐ and high‐textured pyrolytic carbon matrices.
