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

What is claimed is:

1. A system for forming a reinforced metallic structure, comprising:
a tool having a formation surface corresponding to a desired structure shape of the reinforced metallic structure;
a plurality of fibers configured to be positioned on the formation surface of the tool; and
a cold-spray gun configured to output a gas including metallic particles towards the formation surface at a velocity sufficiently great to cause the metallic particles to bond together around the plurality of fibers to create the reinforced metallic structure.

2. The system of claim 1 , further comprising a restraint for securing at least two fibers of the plurality of fibers together such that the at least two fibers of the plurality of fibers resist separation in response to depositing the metallic particles on the plurality of fibers.

3. The system of claim 1 , wherein the plurality of fibers includes a first group of fibers configured to be oriented in a first direction and a second group of fibers configured to be oriented in a second direction that is perpendicular to the first direction.

4. The system of claim 3 , wherein the first group of fibers is configured to be woven together with the second group of fibers.

5. The system of claim 1 , wherein at least one of the plurality of fibers includes a metallic fiber interface coating.
