AN INVESTIGATION OF CARBON DEPOSITION IN CHARS. II
Abstract
The techniques for the investigation of char densification phenomena which had been developed under a previous contract were extended to include transpiration experiments with gases and gas mixtures typical of the decomposition products of phenolic resins. As before, the chars used in the experiments were produced by charring high performance carbon cloth phenolic composities in a plasma jet. Data on the structural characteristics and permeabilities of the chars, and the change occurring during transpiration, are presented. Comparisons of the experimental data with kinetic rate data from the literature are made. A simplified program for calculating the change in permeability required to extend this program to more complex situations is discussed.
