Abstract
In a method of manufacturing fiber-reinforced engine components having a metal matrix, a long or even continuous silicon carbide fiber is first coated with a matrix metal of a titanium-based alloy by atomizing or sputtering. Then, the fibers coated with matrix material are wound onto a mold in the direction of the anticipated stresses. A covering of foils, bands, wires, pressed-on granulates, sintered-on powders or a top coating of matrix metal is then applied onto the surface of the fibers wound onto the mold. Finally the mold with the wound-on, matrix-material coated fibers and the covering of matrix metal is subjected to hot isostatic pressing. This method is used to manufacture engine shafts, shroud bands for turbine wheels or disk-less turbine wheels having retaining rings holding the blades.
