Abstract

A method for forming a reinforced metallic structure includes providing a tool having a formation surface corresponding to a desired structure shape of the reinforced metallic structure. The method also includes positioning a plurality of fibers on the formation surface of the tool. The method also includes depositing a layer of material on the plurality of fibers using a cold-spray technique. The method also includes removing the layer of material with the plurality of fibers from the tool to create the reinforced metallic structure.

First claim

The invention claimed is:

1. A method for forming a reinforced metallic structure, comprising:
applying a metallic fiber interface coating circumferentially around each of a plurality of fibers, the metallic fiber interface coating including a metal;
positioning the plurality of fibers on a formation surface of a tool after applying the metallic fiber interface coating, the formation surface corresponding to a desired structure shape of the reinforced metallic structure;
depositing a layer of metal material on the plurality of fibers using a cold-spray technique after the positioning the plurality of fibers on the formation surface; and
removing the layer of metal material with the plurality of fibers from the tool to create the reinforced metallic structure.

2. The method of claim 1 , further comprising depositing a base layer of material on the formation surface of the tool using the cold-spray technique prior to positioning the plurality of fibers on the formation surface.

3. The method of claim 1 , wherein the plurality of fibers on the formation surface of the tool include a first group of the plurality of fibers oriented in a direction parallel to each other.

4. The method of claim 3 , wherein at least two fibers of the plurality of fibers are secured together prior to depositing the layer of material on the plurality of fibers such that the at least two fibers of the plurality of fibers resist separation in response to depositing the layer of material on the plurality of fibers.

5. The method of claim 3 , wherein the plurality of fibers on the formation surface of the tool further includes a second group of the plurality of fibers oriented parallel to each other and perpendicular to the first group of the plurality of fibers.

6. The method of claim 5 , wherein the first group of the plurality of fibers are woven together with the second group of the plurality of fibers.

7. The method of claim 1 , wherein each of the plurality of fibers includes at least one of alumina, boron, silicon carbide, silicon nitride, a glass, a ceramic material, or a metal.

8. The method of claim 1 , further comprising flipping the reinforced metallic structure so a second side of the plurality of fibers faces a cold-spray applicator, and applying a second layer of material to the second side of the plurality of fibers.

9. The method of claim 8 , further comprising positioning a second plurality of fibers on the second layer of material and applying a third layer of material to the second plurality of fibers.

10. The method of claim 1 , wherein positioning the plurality of fibers on the formation surface of the tool includes orienting the plurality of fibers in a desired orientation.
