The promise of metal matrix and ceramic matrix composites has been acknowledged for many years but implementation has been limited by th4 lack of a suitable reinforcement fiber. An ideal fiber would have a small diameter combined with superior mechanical properties. The YAG alumina eutectic fiber would provide these properties. This fiber has shown excellent strain rate dependant tensile properties as well as good elevated temperature fast fracture strengths (1.38GPa @ 1094oC). The major issues with the YAG alumina eutectic fiber are the lack of a small enough diameter fiber and the significant cost. To address this need, we are proposing the development of a 75 micron diameter YAG alumina eutectic fiber. This fiber has the promise of being an excellent reinforcement for composites used in turbine aircraft engines.
