Abstract
A method for forming a sheet structure includes providing a tool having a formation surface corresponding to a shape of the sheet structure. The method also includes depositing at least one layer of material on the formation surface using a cold-spray deposition technique. The method also includes removing the at least one layer of material from the formation surface to create the sheet structure.
Claims6
A method for forming a sheet structure, comprising:
- providing a tool having a formation surface corresponding to a shape of the sheet structure;
- removing a portion of the formation surface of the tool to form a recess in the formation surface, the recess having an angle that is greater than 90 degrees to allow particles to bond together in the recess;
- depositing at least one layer of material on the formation surface using a cold-spray deposition technique, including depositing a greater amount of material in the recess on the formation surface such that the sheet structure has a greater thickness at a location corresponding to the recess;
- and
- removing the at least one layer of material from the formation surface to create the sheet structure.
