Abstract
A method of preparing a ceramic fabric for use in a ceramic matrix composite includes transforming a ceramic tow from a first tow geometry to a second tow geometry, thereby reducing a first dimension of the ceramic tow and increasing a second dimension of the ceramic tow orthogonal to the first dimension to produce a flattened tow. The method includes weaving or braiding the flattened ceramic tow to form a ceramic fabric.

A method of preparing a ceramic fabric for use in a ceramic matrix composite, the method comprising:
- transforming a ceramic tow from a first tow geometry to a second tow geometry, thereby reducing a first dimension of the ceramic tow and increasing a second dimension of the ceramic tow orthogonal to the first dimension to produce a flattened ceramic tow;
- weaving or braiding the flattened ceramic tow to form the ceramic fabric, wherein the second dimension of the flattened ceramic tow is oriented parallel to a surface of the ceramic fabric;
- and
- removing a size material from the ceramic tow prior to transforming the ceramic tow.
