Claim 8:
9. A ceramic matrix composite airfoil comprising: a leading edge; a trailing edge opposite the leading edge; a pressure side extending from the leading edge to the trailing edge; a suction side opposite the pressure side and extending from the leading edge to the trailing edge; a hollow core cavity adjacent the leading edge and between the pressure side and the suction side; a trailing edge void between the leading edge and the trailing edge, and between the pressure side and the suction side; and a cross brace formed in the trailing edge void, the cross brace having an “X” shaped cross-sectional geometry, wherein the cross brace partially defines a plurality of sub-cavities; and wherein a shared wall separates a first of the plurality of sub-cavities from the hollow core cavity.
