预氧化过程中张力对聚丙烯腈预氧化纤维微缺陷结构的影响
Effect of Tension on the Microvoids Structure of Polyacylonitrile (PAN) Fibers During the Thermal Stabilization Stage
摘要
Abstract
The effect of tension on the microvoids of polyacylonitrile ( PAN) thermal stabilized fibers was investigated by small angle X-ray scattering ( SAXS) at Shanghai Synchrotron Radiation Facility ( SSRF) at beamline BL16B. All SAXS patterns exhibit a very big anisotropy between the equator and meridian direction. The results indicate that the scattering bodies are elongated and oriented in direction of fiber axis. The quantitative parameters of orientation, length, diameter of the microvoids were obtained. The results show an obvious effect of tension to the microvoids' structure-a narrowing of the distribution of the microvoids misorientation and a more slender shape of microvoids, compared with the case without tension.关键词
