Abstract
CMC yarn is formed on the outer surface of a mandrel, generally tracking the shape of the mandrel outer shape. CMC fabric layers are formed outwardly of the shear tube to form a desired shape of a final airfoil leading edge. The mandrel, and the shear tube are provided with a shape at at least one of the mandrel radially inner and outer ends to be spaced from the desired final shape of the airfoil leading edge at a corresponding one of a fabric radially inner and outer ends. A filler material is inserted into a space between the corresponding one of a fabric radially inner end and a fabric radially outer end of the fabric layers.
