摘要
炭纤维的性能很大程度上取决于原丝。不同纤维素原丝及其制备的炭纤维均具有分形结构。本文通过小角X射线散射(SAXS)法定量分析不同纤维素原丝及其制得的炭纤维的孔结构参数,并讨论了分形维数与结构和性能之间的关系。
The strength of carbon fibers rather depends on their precursors. The precursors and carbon fibers all have ractinoal feature. In this paper,we quantitatively analyze the porous structure parameter and the ralation ship of ractional features dimension and the structure are discaesd, properties of different precursors and their carbon fibers by small angle X-ray scattering(SAXS) method.
