Woven reinforcing fiber airfoil structure for a turbine engine

A turbine engine comprising:

• an airfoil comprising:
• a non-uniform weave structure that is two-dimensional or three-dimensional, the non-uniform weave structure comprising a plurality of reinforcing fibers, the non-uniform weave structure having a first region with a first stiffness and a second region with a second stiffness higher than the first stiffness, the first region corresponding to a center core region of a thickness of the airfoil,
• wherein the plurality of reinforcing fibers include higher density fibers in the second region and lower density fibers in the first region so as to increase a stiffness of the airfoil at the second region of the airfoil in a desired orientation to achieve a desired aeromechanics response of the airfoil, and
• wherein the plurality of reinforcing fibers comprises a first plurality of reinforcing fibers, a second plurality of reinforcing fibers, and a third plurality of reinforcing fibers, wherein the second plurality of reinforcing fibers and the third plurality of reinforcing fibers are substantially perpendicular to the first plurality of reinforcing fibers.
