Ceramic Composite Combustor Cans for Expendable Turbine Engines
Ceramic matrix composite fabrication by microwave assisted chemical vapor infiltration (MWCVI) has been demonstrated as a feasible, faster, and more economical technique as compared to conventional CVI. Two deposition systems, carbon and silicon carbide, were investigated using this processing techn...

| description | Ceramic matrix composite fabrication by microwave assisted chemical vapor infiltration (MWCVI) has been demonstrated as a feasible, faster, and more economical technique as compared to conventional CVI. Two deposition systems, carbon and silicon carbide, were investigated using this processing technique. Densification rates over an order of magnitude higher have been achieved on small cylindrical Nicalon fiber preforms. Economic forecasts based on previous SiC depositionandthis Phase I work shows a significant improvement in part cost as compared to conventional CVI work. A reduction in cost of a factor of 20 has been calculated. A larger, commercial microwave system has been designed for scaled up prototype part fabrication. |
