摘要: A carbon/carbon part and processes for making carbon/carbon parts are provided. The process involves inserting a polyacrylonitrile preform (PAN preform) into a furnace, introducing an inert atmosphere into the furnace, and ramping up the furnace to a temperature greater than 1200° C. while maintaining the total pressure in the furnace greater 0.5 Atm. The method may convert the PAN preform into a carbon preform. The carbonization may be completed while maintaining the total pressure in the furnace greater than 0.5 Atm.
