Abstract
There is disclosed a method of forming a fabric 1 on the surface of a mandrel 10, infiltrating the formed fabric with matrix, and leaving portions 12a, 12b of the mandrel as integral with the fabric and removing the mandrel before the fabric adheres to the mandrel by matrix infiltration. Subsequently, a remaining portion of the mandrel is used as a reference surface and machining is performed. Without possibility of adhesion to the mandrel and resulting breakage, machining bases (axial center and reference surface) during machining can accurately be provided, and this can largely enhance machining precision and yield of a final product.
