Abstract

The project will continue to develop a novel processing method for carbon-carbon composite manufacture with reeduced processing time and, therefore, reduce costs. Current carbon deposition processes are unacceptable slow and expensive. The new feature of the4 process is the deposition of an iron oxide (magnetite) catalyst onto a preform of carbon fibers to catalyze the decomposition of methane and deposition of carbon on the surface of the fibers. Phase I tests have shown that this unique catalyst can increase the rate of carbon formation by more tha an order of magnitude. This represents a dramatic breakthrough in carbon-carbon processing technology. Phase II will: A. Scale-up Phase I using larger preforms of carbon fiber and existing equipment. B. Produce carbon-carbon composites in the furnaces of a major U.S. Manufacturer. C. Measure properties, such as density, oxidative stability, thermal conductivity and wear resistance, of the composites for comparison to current values. D. Determine properties as a function of processing parameters E. Fit applications to properties.
