Description:

Repair of aircraft wings can be very expensive and the mechanical properties of the repair may not match those of the parent material. One potential method of repairing these components is friction stir welding.

This project will produce friction welds in aircraft alloys. The fatigue properties of these materials will be determined and this information fed into stress analysis software to compare the performance of the repaired section to that of the original component.
