Abstract:
A method for manufacturing an airfoil is provided which includes the steps of: a) providing a billet of discontinuously reinforced aluminum having at least 10 volume percent of silicon carbide as a reinforcing element, and no more than 30 volume percent of silicon carbide as the reinforcing element; 2) extruding the billet into an airfoil shaped geometry from a die, wherein the geometry includes a first wall, a second wall disposed opposite the first wall, a leading edge, a trailing edge disposed opposite the leading edge, and a first cavity disposed between the first and second walls, and the leading and trailing edges.
