Abstract
An improved method for coating ceramic fibers and woven cloths of ceramic fibers is disclosed, wherein the ceramic fibers are thoroughly wetted with precursors in a solution before the precursors react to form a coating by heterogeneous nucleation and growth. The fibers are then rinsed and fired and, where desired, the process may be repeated in stages to increase the coating thickness as desired. This method is amenable to operation in both the batch and continuous modes. This flexible method reduces both the cost and time of producing ceramic matrix composites (CMCs).
