Abstract

Systems and methods for manufacturing unidirectional fiber prepreg tapes for CMC articles are provided. In one exemplary aspect, the method includes casting a matrix material on a carrier film to form a matrix film. The matrix material of the matrix film is then allowed to dry for a predetermined time. The matrix film is then wrapped on a drum and the matrix material is wet to a predetermined viscosity with a solvent. Thereafter, a fiber tow that includes of a plurality of fibers is wound about the drum so that the fiber tow penetrates into the matrix material and the matrix material impregnates the fiber tow to form the prepreg tape.
