ABSTRACT:
In the production of all-carbon composite articles by the cracking of a hydrocarbon gas to deposit carbon on a fibrous carbon substrate the substrate is held in the furnace by a ram movable in the furnace to engage the substrate. The gas is introduced inside the annular substrate and evacuated at a position spaced laterally from the substrate so that the gas is forced to disperse through the substrate wall.
