Two-dimensional carbon/carbon composites were densified with carbon by pyrolysis of propane using the pulse chemical vapor infiltration (CVI) process which repeats the cycle of evacuation and introduction of gas. The experimental parameters were deposition temperature, reactant gas concentration, fl

✦ Synopsis
Early work on preparing carbon-carbon composites by using chemical vapor infiltration is discussed. Later work showed little influence of substrate on infiltration kinetics. and confirmed earlier relationships between property values and density. Yields of total carbon, soot, and CVD carbon are explained using different collision efficiencies of gas phase constitutents.
