Abstract :
The thermal stability of fluorine-intercalated carbon fibres has been studied using differential thermal analysis and thermogravimetry. The selected host fibres were polyacrylonitrile-based and pitch-based carbon fibres, either as-received or heat-treated at 3000 °C. Fluorination performed at room temperature in the presence of hydrogen fluoride led to stage-1 compounds for the most graphitized samples. The thermal stability was found to depend on the host structure and on the amount of intercalated fluorine.
