Zusammenfassung:	The present application provides methods (100) for processing ceramic fibers (30) for the manufacture of ceramic matrix composites (CMCs). One method may include providing at least one frame (40) including a planar array (34) of unidirectional ceramic fibers (30) extending across a void (50) thereof. The method may further include at least one of depositing (104) a coating on the ceramic fibers (30) of the at least one frame (40) via a chemical vapor deposition (CVD) process and impregnating (106) the ceramic fibers (30) with a slurry (38) including a ceramic matrix precursor composition to form at least one CMC prepreg (60). In some embodiments, the ceramic fibers (30) of the planar array (34) may include a coating, and the method may include impregnating the coated ceramic fibers (106) with a slurry (38) including a ceramic matrix precursor composition to form at least one CMC prepreg (60).
