Abstract: In this paper, a new additive manufacturing process, referred to as Composite Metal Foil Manufacturing, has been introduced and used to produce peel and tensile testing specimens. Three peel tests under different settings were performed with the first two included analysing the effect of different peeling rates and corrosion on Al99.5 foils. The third test assesses the peel strength of aluminium/copper composites. The results show that the rate of peeling and corrosion did not have a significant effect on the peel strength. The composites also exhibited results that are consistent with previous tests, proving that the performance of the new process remains equally effective. The tensile test demonstrates that the part produced by the proposed process is 8% stronger than a part machined out of a solid aluminium block. The results prove that the process is capable of producing consistent results as well as stronger parts compared to traditional machining methods.
