Abstract:

This study concerns the chemical and structural changes that occur during thermal treatment of mesophase pitch-based carbon fibers. This task was part of a larger project sponsored by the Manufacturing Technology Program of the Department of the Navy aimed at producing high thermal conductivity carbon fibers from a thermally polymerized petroleum residue. The pitch was melt spun into circular- and ribbon cross section fibers, having radial point and line-origin textures, respectively. Then, the stabilization and carbonization processes were studied using a combination of dynamic and post-treatment techniques.
