Zusammenfassung:	A turbine diaphragm airfoil, a turbine diaphragm assembly employing such an airfoil, and a method of repair are described. In one embodiment, a turbine diaphragm airfoil includes: a composite airfoil body which includes a pressure side and a suction side, the composite airfoil including: a leading edge section forming a portion of each of the pressure side and the suction side; and a trailing edge section integral with the leading edge section, the trailing edge section including: a prefabricated member affixed to the leading edge section, the prefabricated member forming a remainder of the pressure side of the composite airfoil body; and a weld or braze section contacting the leading edge section and the prefabricated member, the weld or braze section forming a remainder of the suction side of the composite airfoil body.
