Abstract:
Currently, issues related to reducing costs and improving environmental efficiency are becoming increasingly relevant in the process of carbon fiber production. The article presents the results of research and developments conducted over the past few decades in the field of using ionizing radiation for the pre-treatment of polyacrylonitrile fiber (PAN) before thermo-oxidative stabilization in production, aimed at reducing the cost of technology and improving the properties of the resulting carbon fibers. The processes of free radical formation and the mechanisms of cyclization initiation of irradiated fibers are discussed.
