Investigation of the Deformation Behaviour and Resulting Ply Thicknesses of Multilayered Fibre–Metal Laminates

Multilayered fibre–metal laminates (FMLs) are composed of metal semifinished products and fibre-reinforced plastics, benefit from the advantages both material classes. Light metals in combination with thermoplastics highly suitable for mass production lightweight structures good mechanical properties. As formability light sheets is sometimes limited at room temperature, increasing process temperature an appropriate approach to improve formability. However, melting thermoplastic materials resulting loss stiffness limit processing temperature. Since single-ply layers have different through-thickness stiffnesses, forming changes ply thickness multilayered laminate. In present study, deformation behaviour FMLs was investigated using a two-dimensional finite-element model assuming plane strain. The thermoelastic-plastic analysis made investigation variation possible by incorporating sufficient mesh direction. results indicate that can predict delamination plies during deformation, as well final product. Additionally, predicted agreement experimental when temperature-dependent friction coefficient used.
