Abstract Scope |
An ever-present mantra of sustainable production and consumption: reduce-reuse-recycle (RRR) is easy to remember, but challenging to implement. Additive friction stir deposition (AFSD) is a solid-state additive manufacturing (AM) technique for metals. An emerging functionality of AFSD is its ability to embody each aspect of RRR sustainability considerations. AFSD applicability to reduction and recycling are briefly discussed, highlighting the flexibility of feed material inputs, and low embodied energy. Fully, we discuss novel results wherein AFSD is used for the repair of fastener holes in aircraft frames, thereby enabling the reuse of damaged parts and components. An AFSD processing strategy capable of successfully repairing simulant fastener holes is developed. This strategy does not include post-repair cold working or furnace treatments. Repair quality is quantified through high-cycle fatigue testing, proving the repairs are mechanically significant, and demonstrating the capacity of AFSD for reusability of parts through functional repairs. |
