Abstract
Fibre metal laminates (FMLs) have been developed as promising materials in the manufacture of aircrafts. In order to reduce costs during the manufacture process, relatively new forming techniques are required. In this work, shot peen forming process was performed on Ti/CFRP laminates. Additionally, effects of shot peening parameters on the forming characteristic of Ti/CFRP laminates were investigated. The results showed that the peening coverage and the final arc height of the FML strip were increased with the extension of the exposure time. Similarly, the final arc height of the FML strip increased linearly with the augment of the applied Almen intensity. Moreover, FML with different lay-ups showed diverse forming characteristics. It was more difficult to generate the bending deformation in the FML made with unidirectional lay-up prepreg. Finally, an improvement in tensile properties of the FMLs was confirmed after the shot peening treatment.
