Abstract: PROBLEM TO BE SOLVED: To manufacture a light air foil, having rigidity adaptable to a load generated by a gas turbine engine, at a low cost. SOLUTION: An air foil 30 of which, for example, a fan outlet guide vane consists has a body with geometrical cross section comprising a first wall 44; a second wall 46 arranged opposite to the first wall; a front edge 48; a rear edge 50 arranged opposite to the front edge; and at least one of cavities 52 and 54. The cavities 52 and 54 are formed between the first and second walls 44 and 46 and between the front and rear edges 48 and 50. The air foil 30 is extrusion-molded by using non-continuous reinforced aluminum such that the body with geometrical cross section is extended between first and second ends.

Abstract: The invention provides a hollow airfoil which is extruded from discontinuously reinforced aluminum (DRA). Preferably the DRA include silicon carbide particles as a reinforcing element. Preferably the silicon carbide is present in an amount between 10-30 volume percent, most preferably 17.5 volume percent. The matrix material is preferably a 6000 aluminium alloy.
