1. A system for coating ceramic fibers for use in manufacturing a ceramic matrix composite (CMC) article, the system comprising:
a frame comprising a plurality of frame members including a first frame member at a first end of the frame and a second frame member at an opposing second end of the frame, the first frame member and the second frame member defining a void therebetween, wherein the frame includes one or more additional frame members extending across the void between the first and second frame members, at least one of the plurality of frame members comprising a hollow body and at least one perforated hole defined in the hollow body, wherein the ceramic fibers are securable at the first and second ends of the frame so as to extend across the void;
a coating material; and
an inlet in fluid communication with the at least one perforated hole of the hollow body so as to allow a coating material to flow into and through the hollow body and out of the at least one perforated hole at a location of at least a portion of one of the ceramic fibers,
wherein the at least one perforated hole is configured to cause the portion of one of the ceramic fibers to separate from the frame such that the portion is uniformly coated with the coating material.
