【Abstract】 Oxidized polyacrylonitrile fiber, a new material for civil use with combustion resistance, flame resistace, corrosion resistance and abradability properties, can be made on the basis of the thick tows of PAN fiber containing itaconicacid or acrylic sodium sulphoacid through stepwise oxidation and airflow distributing device. Control of reaction heat removal, increase of reaction temperature and rate as well as reduction of reactant residence time are essential factors.更多还原
