Discontinuously reinforced aluminum gas turbine guide vane

A fan exit guide vane assembly, comprising:

• a plurality of guide vanes, each extruded from 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 said reinforcing element, and each guide vane having first and second ends, a cavity, a leading edge, and a trailing edge;
• an outer case;
• an inner case, disposed radially inside of and substantially concentric with said outer case;
• wherein said guide vanes extend between said inner and outer cases, and are circumferentially distributed between said inner and outer cases.

An airfoil, comprising:

• a cross-sectional geometry which includes a first wall and a second wall disposed opposite said first wall, a leading edge and a trailing edge, and a first cavity disposed between said first and second walls and said leading and trailing edges;
• a first end and a second end, said cross-sectional geometry extending between said first and second ends;
• and
• wherein said airfoil is extruded from discontinuously reinforced aluminum, and said discontinuously reinforced aluminum includes a 6000 series aluminum alloy matrix and silicon carbide as a reinforcing element.

An airfoil, comprising:
