Abstract

A ceramic matrix composite (CMC) airfoil component can be made by forming a stack of fabric plies with a plurality of plies adhered together with a tackifier. The stack of fabric plies is machined into an airfoil shape to form an airfoil core (220) with an orientation of the fabric plies selected based upon strength and/or performance requirements of the airfoil component. The airfoil core (220) is then overwrapped with an outer mold layer (230) formed of one or more plies of fabric to form a preform (200). The preform (200) is then densified, such as via melt infiltration (MI) and/or chemical vapor infiltration (CVI), to form the CMC airfoil component such as a turbine vane or a turbine blade.
