Abstract : A study has been made of the structure of carbon fibers from hydrocellulose and Polymers (PAN) after heat treatment in the temperature range 800-3000C and of carbonized fibers from PAN after oxidation in air. It has been established that substantial change in surface structure takes place after heat treatment at a temperature of 2600C or higher. Structural changes in carbonized fibers after different degrees of oxidation are shown. Data are also given on change of surface structure and the formation of porous structure in carbons during oxidation under defined conditions. (Author)
