<P>PROBLEM TO BE SOLVED: To provide a friction member based on a C/C composite material which is well-matched between wear resistance and friction/wear and exhibits stability of oxidation resistance and braking performance. <P>SOLUTION: The C/C composite material is obtained by densification with a pyrolytic carbon matrix originating from a precursor in gaseous state at least in a main external phase of the matrix, and, at the end of the densification, final heat treatment is performed at a temperature lying in the range of 1,400-1,800°C. <P>COPYRIGHT: (C)2011,JPO&INPIT |
