Oxidation behavior of PAN based carbon fiber reinforced phenolic resin matrix composites

The results of studies on oxidation behavior of composites developed by employing PAN based carbon fibers of different properties was investigated. Unidirectional polymer composites were prepared using three types of PAN based fibers. The composites were prepared by match mold die technique, and different heat treated composites were characterized for crystalline dimensions using wide angle X-ray diffraction.
