Influence of the Thermal Stabilization Conditions on the Structural Transformation of the Polyacrylonitrile Fiber

Abstract:

It was shown that the structure of crystalline component of polyacrylonitrile fiber is represented by two types of coherent scattering domains, whose average sizes differ by an order of magnitude. At the initial stage of thermal stabilization the structure of a polyacrylonitrile fiber is improved: the sizes of coherent scattering domains oriented parallel to the fiber axis grow most actively. An increase in the tensile load improves the texture of the material. Increasing the temperature of thermal stabilization, as well as the tensile load onto the bundle causes a significant reduction in the time during which the process of dispersion of precursor material develops and formation of a new high dispersion phase of thermostabilized fiber.
