本文利用x射线小角散射(SAxs)研究碳纤维原丝预氧化过程中微孔的变化.计算出随着预氧化过程中牵伸比的加大.预氧化丝中微孔结构的变化.预氧化丝中的微孔大多是一些长条状微孔,并且取向趋向于纤维轴方向.碳纤维中的微孔对于其模量有着重大影响,因而对于碳纤维以及其原丝中微孔结构的研究有着重要的意义.

In this paper,Small-angle X-ray scattering has been used to identify the microporosity of the pre-oxidized fibers in different conditions.Given different draw ratios,we use SAXS to find out the changes of the void structures in the pre-oxidized fibers.Microporosity in carbon fibers and pre-oxidized fibers consists primarily of needle-shaped voids whose long axes are oriented preferentially along the fiber axis.The microporosity is the major deciding factor in controlling the modulus of carbon fibers.
