Joining Technologies for Al-Foam-Al-Sheet Compound Structures

The present paper reviews various conventional joining techniques which can be applied for foam‐sheet structures, i.e., riveting, screwing, welding, gluing, and soldering. Additionally, the combined application of riveting and gluing is presented. The properties of the joints are investigated with the help of model structures in bending and tensile shear tests. Finally, the transferability of the utilized joining methods to component like parts is shown with the corresponding properties of the compound structures in torsion and dynamic bending tests.
