| Abstract: | The technological model of thermal gradient CVI was presented. Based on this model, the temperature distribution within a cylindrical carbon felt was calculated, and the method for controlling the deposition temperature in thermal gradient CVI was suggested. Based on this method, C/C composites of 160 mm in inner diameter, 390 mm in height, 20 mm in thickness were fabricated with the infiltration time being less than 100 h. The density of the final C/C composite reached up to 1.6 g/cm3. |
