利用Ar+激光在514.5 nm处对3D-LCVD生长的碳纤维的内部结构进行了表征。纤维沿轴向面抛光。在半径附近采集了几个光谱，对纤维成分进行了分析。通过记录峰的位置和宽度变化，对每个光谱进行了分析。比较了光谱中G、D、D′和G′峰的强度。我们的分析表明，碳纤维的内部结构从多晶石墨芯转变为无定形碳外层。
The internal structure of carbon fibers grown by 3D-LCVD was characterized by Raman spectroscopy at 514.5 nm using an Ar+ laser. Fibers were polished along an axial plane. Several spectra were taken alongside the radius to perform an analysis of the fiber composition. Each spectrum has been analyzed by noting the peak positions and width changes. Intensities of the G, D, D′ and G′ peaks were compared between spectra. Our analysis shows that the internal structure of carbon fibers changes from a polycrystalline graphite core to an amorphous carbon outer layer.
