Abstract
This paper describes a new process to synthesize crystalline oxide fibers for high temperature structural applications. Strong and chemically homogeneous precursor fibers of 5-40 μm diameter were made at rates of up to 1.6 m s-1 by glass fiber pulling techniques from undercooled molten oxides. The precursor fibers were heat treated at temperatures up to 1873 K to make crystalline fibers with controlled grain size and properties. Tensile strengths of the precursor fibers were up to 5-6 G Pa (900 ksi) for YAG- (Y3Al5O12) and mullite- (Al6Si2O13) compositions. Research to optimize fiber compositions and crystallization processes, and to scale up precursor fiber production is discussed.
