Abstract
A ceramic matrix composite (CMC) vane or layup therefor includes first and second platforms, and an airfoil portion extending therebetween. The airfoil portion includes a first portion of a shear tube extending relatively orthogonal to the first and second platforms, wherein the first portion of the shear tube extends through the first and second platforms, and wherein the first portion of the shear tube defines a leading edge and a hollow core of the airfoil portion. A second portion of the shear tube is connected to the first portion of shear tube and extends relatively orthogonal to the first and second platforms, wherein the second portion of the shear tube also extends through the first and second platforms, and wherein the second portion of the shear tube includes a Y-weave ply and a trailing edge noodle that define a trailing edge of the airfoil portion.
