Investigation of the structure of carbon fibers by means of the scanning electron microscope

  • 28 Accesses


The structure of carbon fibers based on hydrated cellulose and polyacrylonitrile after heat treatment between 800 and 3000°C and of carbonized fibers based on polyacrylonitrile, submitted to oxidation in air, was investigated. It was established that significant changes in the surface structure occur after heat treatment at 2600°C and above. Structural changes in the carbonized fibers after various degrees of oxidation were demonstrated. Additional data were obtained on the change in the surface structure and the formation of a porous structure in carbon materials during oxidation under certain conditions.
