Carbon/Carbon composite was been manufactured by the technology of warmer-moiding process of clutter chopped carbon fiber, using phenolic resin as an adhesive. The degree of graphitization, the microstructure and the friction properites were studies. The results show that the clutter chopped fiber fully scatter in the carbon/Carbon composite and the degree of graphitization of phenolic resin can reach up tp 86.2%, this matrix carbon can from the continuous and stable graphitic thin film on the friction surface during braking process so that the composite has fine friction properties and low wear rate.
