【摘要】 本文综述了利用广角X射线衍射分析研究聚丙烯腈(PAN)纤维制备碳纤维的预氧稳定化过程。X射线衍射法在表征PAN原丝纤维序态结构、玻璃化转变及PAN纤维在预氧化阶段的环化动力学方面已获得了广泛的应用。更多还原

【Abstract】 The procedures of preoxidaiion stabilization of carbon fiber from PAN precursors by wide-angle X-ray diffraction are discussed in this paper. X-ray diffraction has been widely applied in the characterization of order state structure, vitrification transformation of PAN fiber and cyclization dynamic of PAN fiber during Preoxidation,更多还原
