Abstract: Frame for use in coating a reinforcing fiber are provided. The frame includes a first frame end having a first cross-sectional shape. The first cross-sectional shape has one or more contact locations that are spaced apart from each other. The reinforcing fiber contacts the first frame end at the one or more contact locations. Methods are also provided for coating such a fiber.

Abstract: A ceramic fiber processing apparatus and method for processing ceramic fibers for the manufacture of ceramic matrix composites (CMCs) is provided. The apparatus includes a frame including a plurality of unidirectional ceramic fibers wound thereabout and extending across a void therein the frame to define a first planar array of ceramic fibers and a second planar array of ceramic fibers. During use, the frame is disposed in the ceramic fiber processing apparatus in a manner to enable gripping of the first planar array of ceramic fibers with a first gripper assembly and gripping of the second planar array of ceramic fibers with a second gripper assembly. A cutting mechanism provides cutting of the plurality of unidirectional ceramic fibers to separate the first planar array of ceramic fibers and the second planar array of ceramic fibers from one another.

Abstract: The present application provides methods and apparatus for processing ceramic fibers for the manufacture of ceramic matrix composites (CMCs). One method may include providing at least one frame including a planar array of unidirectional ceramic fibers extending across a void thereof. The method may further include at least one of depositing a coating on the ceramic fibers of the at least one frame via a chemical vapor deposition (CVD) process and impregnating the ceramic fibers with a slurry including a ceramic matrix precursor composition to form at least one CMC prepreg. In some embodiments, the ceramic fibers of the planar array may include a coating, and the method may include impregnating the coated ceramic fibers with a slurry including a ceramic matrix precursor composition to form at least one CMC prepreg.
