THE MANUFACTURING OF C/C COMPOSITE BRAKE DISK BY MEANS OF THERMAL GRADIENT CVD DENSIFICATION TECHNIQUE

Using a new device developed in National Key Lab for Powder Metallurgy, the feasibility of the manufacturing of high performance C/C composite brake disk by means of thermal gradient CVD densification technique has been systematically investigated. The influence of the parameters, such as temperature, gas pressure, gas flow rate on CVD densification, as well as the charactoristics of dynamics during the densification process were studied, and the manufacturing of high dense C/C disk in a more short period was successfully realized, showing a bright prospect of this technique for commercial application.
