A turbine vane made from ceramic matrix composite material and adapted for use in a gas turbine engine. The turbine vane is made from ceramic matrix composite materials with three-dimensionally woven or braided reinforcing tows and includes an inner band, an outer band, and an airfoil that extends between the inner band and the outer band.

Composite turbine vane with three-dimensional fiber reinforcements

A composite blade includes a preform and a binder. The preform is a preform of yarns woven in three-dimensions and has a tip region, a root region and an intermediate region. The intermediate region is positioned between the tip region and the root region. The yarns comprise warp yarns and weft yarns. The warp yarns form a longitudinal axis. The weft yarns are positioned at a 90 degree angle to the warp yarns. The weft yarns increase in yarn size as determined by filament count along the longitudinal axis to change the thickness of the preform. The binder maintains the relative positions of the preform yarns.

A near netshape carbon preform is provided comprising a polar woven fabric of a plurality of carbon yarns, said polar woven fabric having a helical shape and an adjustable fiber orientation distribution, said polar woven fabric being laid down, turn by turn, into a near net shape preform, and each layer of said fabric being needled to produce a near net shape preform with increased interlaminar strength, an adjustable fiber orientation distribution and enhanced thermal conductivity. A method for manufacturing a near net shape carbon preform with a polar woven substrate is also disclosed.
