Abstract

A gas turbine engine and a composite apparatus is disclosed. The gas turbine engine includes a composite apparatus body formed from a composite material, the composite material including a three dimensional preform, the three dimensional preform including a plurality of warp fibers disposed in a warp direction in a first plane, a plurality of fill fibers disposed in a fill direction, wherein the fill direction is perpendicular to the warp direction in the first plane, a plurality of z-yarn fibers disposed in a z-yarn direction, wherein the z-yarn direction intersects the warp direction through the first plane, and a plurality of bias fibers disposed in a bias direction, wherein the bias direction is not aligned with the warp direction and the fill direction.

Claims (25)

1. A fan blade comprising:

a fan blade body formed from a composite material, the composite material including a three dimensional preform, the three dimensional preform consisting of:

a plurality of warp fibers disposed in a warp direction in a first plane;

a plurality of filling fibers disposed in a fill direction, wherein the fill direction is perpendicular to the warp direction in the first plane;

a plurality of z-yarn fibers disposed in a z-yarn direction, wherein the z-yarn direction intersects the warp direction through the first plane; and

a plurality of bias fibers disposed in a bias direction, wherein the bias direction is not aligned with the warp direction and the fill direction and the bias direction is disposed in the first plane.

2. The fan blade of claim 1 , wherein the fan blade body includes a root portion and an airfoil portion.

3. The fan blade of claim 2 , wherein the root portion is thicker than the airfoil portion.

4. The fan blade of claim 1 , wherein the fan blade body is formed from a plurality of composite layers.

5. A gas turbine engine comprising:

a composite apparatus body formed from a composite material, the composite material including a three dimensional preform, the three dimensional preform consisting of:

a plurality of warp fibers disposed in a warp direction in a first plane;

a plurality of filling fibers disposed in a fill direction, wherein the fill direction is perpendicular to the warp direction in the first plane;

a plurality of z-yarn fibers disposed in a z-yarn direction, wherein the z-yarn direction intersects the warp direction through the first plane; and

a plurality of bias fibers disposed in a bias direction, wherein the bias direction is not aligned with the warp direction and the fill direction and the bias direction is disposed in the first plane.

6. The gas turbine engine of claim 5 , wherein the composite apparatus body is formed from a plurality of composite layers.

7. The gas turbine engine of claim 5 , wherein the composite apparatus body is a fan blade body.

8. The gas turbine engine of claim 7 , wherein the fan blade body includes a root portion and an airfoil portion.

9. The gas turbine engine of claim 7 , wherein the root portion is thicker than the airfoil portion.

10. The gas turbine engine of claim 5 , wherein the composite apparatus body is a composite cover for a fan blade.

11. The gas turbine engine of claim 10 , wherein the composite cover includes a root portion and an airfoil portion.

12. The gas turbine engine of claim 11 , wherein the root portion is thicker than the airfoil portion.

13. The gas turbine engine of claim 5 , wherein the composite apparatus body is a fan case.

14. The gas turbine engine of claim 5 , wherein the composite apparatus body is a guide vane.

15. The gas turbine engine of claim 5 , wherein the composite apparatus body is a stator.
