摘要

In this study, nanoscale dynamic mechanical imaging was used to map the storage modulus along the cross section of fibers during the evolution from polyacrylonitrile (PAN) precursors to carbon fibers. The quantitative characterization of skin-core difference in oxidative stabilized fibers indicated that the primary skin-core structure in the fibers forms at 265 °C and the skin-core difference of the final oxidative stabilized fibers in modulus was about 8%. The difference has been enhanced in modulus but reduced in spatial scale during the transition from stabilized PAN fibers to carbon fibers.
