Abstract:

The purpose of this work is to demonstrate the value of single crystal fibers of titanium carbide and titanium boride as fibers for strengthening elements in matrix composite materials. LaserGenics has used the laser-heated pedestal-growth technique to grow short lengths of these materials in fiber form. We were not able to reduce the oxygen content in the growth chamber to a low enough of a level that would ensure single crystal growth. The fibers grown were multicrystaline and, therefore, did not possess the hoped for strength. It is clear from these early growths that single crystal fibers of these matrix materials can be grown. Growth in a reduced level of oxygen should be done and then fibers of significant length should be grown.
