ABSTRACT:
Composite turbine blades and vanes have been proposed in the past formed from nickel or cobalt base superalloys and reinforcing fibres such as tungsten, molybdenum, silicon carbide, or graphite. One of the problems has been the spacing of the fibres and arrangement within the form. The present invention provides for such arrangement by means of aligning the fibres on an alloy powder tape or cloth comprising powdered superalloy and an organic binder. Pieces of the tape are then cut in the desired shape and arranged within a mold and subsequently bonded into a consolidated shape.
