Development and application of hybrid joining in lightweight integral aircraft structures

Project description

A novel hybrid joining technique enhances the mechanical and chemical properties of joints

Joining the large subcomponents of aircraft can be challenging both in terms of the joining process itself and its long-term impact on the integrity of the aircraft. Refill friction stir spot welding is a promising solid-state joining technique using friction to pre-heat and soften a component after which it is shaped to form a joint. The process can lower weight by eliminating fastening elements such as rivets and can also join dissimilar materials. The EU-funded DAHLIAS project is optimising this promising technique and combining it with application of a sealant with adhesive properties. The sealant will not only protect the joint against corrosion but also reinforce its mechanical performance.
