Different samples of precursor at different stages were analyzed using scanning electron microscopy, tensile testing, and X-ray diffraction. The microstructural changes during the preparation process were explored, and some useful conclusions were obtained. These results are of great significance for understanding the microstructure and preparation process of carbon fibers.
