| 20160101459 | Methods for Joining More Than Two Panels Together and Assemblies Formed by the Methods - An assembly for a vehicle and a method of making an assembly including more than three panels stacked together and joined by self-piercing rivets or by clinch joints. A first panel and a second panel are joined together at a first attachment point. A third panel and the first panel are joined together at a second attachment point. A fourth panel and the third panel are joined together at a third attachment point. The first, second and third attachment points are spaced apart to avoid interference between the self-piercing rivets or the clinch joints. | 04-14-2016 |
| 20160144601 | REINFORCED PLATED POLYMERS - A metal-plated component includes a non-metallic core having an outer surface, a metal layer covering at least a portion of the outer surface of the non-metallic core, and a reinforcing structure located within the non-metallic core for increasing the structural capacity of the metal-plated component. A method for reinforcing a metal -plated component includes forming a non-metallic core, positioning a reinforcing structure within the non-metallic core, and depositing a metal layer on the non-metallic core. | 05-26-2016 |
| 20160184921 | FRICTION STIR SPOT WELDING STRUCTURE - A friction stir spot welding structure includes a pair configured of an upper side flange portion and a lower side flange portion that are friction stir spot welded together by being pressed by a rotating pin rotating from one thickness direction side at a mutually overlapping location. A pair of protruding portions that project out in a protruding shape from the upper side flange portion toward the lower side flange portion are formed to the upper side flange portion. A pair of engagement holes into which the pair of protruding portions are inserted are formed to the lower side flange portion. | 06-30-2016 |
