United States Patent Application

View the Complete Application at the US Patent & Trademark Office
In a method of coating a CMC fiber, a multiplicity of fiber tows aligned as a ribbon are simultaneously passed through a reactor and a flow of fiber coating reactant is passed though the reactor to coat the tow fibers. A coating system comprises a reactor chamber to accommodate a multiplicity of fiber tows passing along a path substantially parallel to a longitudinal axis of the chamber and a flow of fiber coating reactant and an aligning structure at an end of the chamber to maintain the multiplicity of fiber tows in a narrow, elongated ribbon configuration. An article comprises a multiplicity of fiber tows aligned in a longitudinal planar array in the form of a ribbon.
