| 20090098369 | FRICTION STIR WELDING OF FIBER REINFORCED THERMOPLASTICS - A fiber-reinforced component is formed of a first composite member including a thermoplastic matrix with reinforcing fibers having a diameter and a length distributed therein in a selected orientation and a second composite member including a thermoplastic matrix with reinforcing fibers having a diameter and a length distributed therein in a selected orientation. The first composite member is bonded to the second composite member by a solid state bond along a predetermined joint path, such that an average volume fraction of the reinforcing fibers of the first composite member and the second composite member within the joint path is substantially the same as an average volume fraction of the reinforcing fibers of the first composite member and the second composite member within the remainder of the fiber-reinforced component. | 04-16-2009 |
| 20090098406 | FRICTION STIR WELDING OF METAL MATRIX COMPOSITES - A fiber-reinforced component is formed of a first composite member including a metal matrix with reinforcing fibers having a diameter and a length distributed therein in a selected orientation and a second composite member including a metal matrix with reinforcing fibers having a diameter and a length distributed therein in a selected orientation. The first composite member is bonded to the second composite member by a solid state bond along a predetermined joint path, such that an average volume fraction of the reinforcing fibers of the first composite member and the second composite member within the joint path is substantially the same as an average volume fraction of the reinforcing fibers of the first composite member and the second composite member within the remainder of the fiber-reinforced component. | 04-16-2009 |
| 20100176182 | FRICTION STIR WELDING SYSTEM - A system, in certain embodiments, includes a backing plate, a tungsten-based member disposed along the backing plate, wherein the tungsten-based member defines a welding work surface, and the tungsten-based member comprises curved grooves configured to secure the tungsten-based member to the backing plate. The system also includes a drive. The system includes a pin tool movable by the drive to create friction along one or more workpieces disposed on the welding work surface, wherein the frictional heating and mechanical stirring is configured to create a stir weld along the one or more workpieces. The system, in some embodiments, also may include a backing plate comprising liquid passages and gas passages and a tungsten-based member disposed along the backing plate, wherein the tungsten-based member defines a welding work surface. | 07-15-2010 |
