| Abstract: | Carbon felt were heat treated at two different temperature, on subsequence the carbon/carbon composites were fabricated with chemical vapor deposition(CVD). The oxidation weight loss rates of the two kinds of samples at different temperature and time were investigated. Graphitization degree and mor-phlogy of the carbon fibers were analysed by X-ray diffraction,and SEM observaion was performed on the samples before and after the test. The oxidation process and the difference cause of oxidation behavior of the two samples were researched. |
