Abstract:

Method of increasing the density of carbon-carbon composite parts. The method may include consecutive steps, as follows: providing the carbon-carbon composite parts, e.g. aircraft brake disc preforms; subjecting the carbon-carbon composite parts to chemical vapor deposition in a CVD furnace; forcing cooling air through the CVD furnace; passing the resulting warmed through a tar trap; cooling the resulting purified, warmed air; repeating the air cooling cycle; and, finally, removing the resulting densified carbon-carbon composite parts from the CVD furnace.
