ABSTRACT

The carbon brake discs were manufactured by densification the carbon fiber preform using PG-CVI technology withdensification time. The results indicate that the densification rate is more rapid before 100 hrs than after 200 hrs. The CT-scanning image and the SEM technology were used to observe the inner subtle structure. CT-images show the densitydistribution in the carbon brake disc clearly. The carbon brake disk made by PG-CVI is not very uniform. There is a densitygradient in the bulk. The high-density part in the carbon brake is really located in the friction surface, especially in the part ofinner circle. This density distribution is most suitable for the stator disc.
