摘要
As an important technical means in the structural characterization of materials, Raman spectroscopy is found sensitive and have significant response to carbon structure in the wavenumber area 0~3300cm-1. Among them, an ideal graphitic lattice C C in-plane vibration mode namely G-band and a consequence of the existence of structural disorder namely D-band are suggested as two of the important index in the study of the carbon structures. Based on these index, a series of structural features such as microscopic stress, crystalline structure, graphitization degree and structural heterogeneity of carbon structures can be obtained. In recent years, with the successful application of a series of new technologies represented by "Mapping" mode, many new developments have been made in the Raman spectroscopy application technologies for carbon fibers. In this paper, taking the applications in the microscopic and mesoscopic aspects of carbon fibers as the starting point, the progress in the Raman spectroscopy studies of microscopic stress/strain, crystalline structure, graphitization degree and structural inhomogeneity of carbon fiber is reviewed. © 2020, Chemical Industry Press Co., Ltd..
