OXIDE EUTECTIC FIBERS FOR HIGH TEMPERATURE COMPOSITES

THE OBJECTIVE OF THIS PROPOSED PROGRAM IS TO TEST THE APPLICATION OF THE EDGE-DEFINED, FILM-FED, GROWTH PROCESS (EFG) TO GROWTH OF REFRACTORY OXIDE EUTECTIC FIBERS. WORK IS DIRECTED TO PRODUCING A RANGE OF MICROSTRUCTURES IN THE GROWN FIBERS BY VARIATION OF GROWTH PROCESS PARAMETERS. THESE RESULTS MAY BE EXPECTED TO INDICATE DIRECTIONS FOR PROCESS AND FIBER PROPERTY OPTIMIZATION. THE EUTECTIC FIBERPRODUCED BY THIS TECHNIQUE WILL FIND APPLICATION IN BOTH CERAMIC-AND METAL-MATRIX COMPOSITE STRUCTURES FOR HIGH-TEMPERATURE SERVICE.
