PAN预氧纤维径向结构的光密度法研究
Optical Density Method of Radial Structure of PAN-based Pre-oxidized Fibers
摘要
Abstract
According to the radial distribution characteristics of PAN pre-oxidized fiber ,the optical density method which can quantitatively characterize the radial structure of pre-oxidized PAN fiber is established ,taking advantage of the light-absorbing of PAN pre-oxidized structure .The results show that when the sample's width is 400 nm and the light intensity is 800 lx ,the optical density method characterize the radial distribution characteristics of PAN pre-oxidized fibers the most effectively and accurately .Compared with the traditional skin-core structure characterization method ,this method not only expresses the pre-oxidized degree in the same domain under different pre-oxidation processes , but also obtains the radial distribution of pre-oxidized degree .Applying this method to the process re-search of pre-oxidized PAN fiber ,the results show that this method can reveal a correlation between the process and structure ,indicating the optical density method as a new method for characterization of PAN pre-oxidized fiber can play an active role in the study of pre-oxidized PAN radial structure .关键词
