$99,488Benefit:
The most significant benefit of FSP followed by SPF will be the eventual implementation of a significantly lower cost fabrication method for moderate sized aluminum welded structures where there is a significant number of detail components. The new technology will enable use of formed components, rather than cut and welded structures, allowing for significant part consolidation. In addition, improved quality should result, since less welding and a lower distortion welding process (friction stir welding) will be used. Applications for this technology include Naval water-tight doors (as will be pursued in Phase II), as well as other closures. Similar applications also exist in other industries including, yachts, and pleasure boats. In addition, large land transportation vehicles such as dump trucks, cement trucks, military vehicles, etc. have a significant number of potential applications. As mentioned, FSP can also be used to enable bending of thick section aluminum in tighter radii at room temperature. This can reduce fabrication costs in a large variety of applications. Similar to FSP followed by SPF, this solution can yield significant part count reduction and elimination of a significant amount of welding. Flanged stiffeners are one such application in the Navy and marine industry. Other industrial applications include armored vehicles, heavy and light duty trucks, and trains, to list a few.
