Fiber-metal laminates (FMLs) are a relatively new type of material developed from the need to develop high performance lightweight structures with excellent properties under tensile, flexure and impact conditions. The first generation of FMLs was based on thermosetting matrices, typically epoxy resins. Recently, new types of FMLs are emerging as a result of the demand for more efficient and lightweight materials for use in the automotive and aerospace industries. This study characterizes the mechanical properties of a new type of thermoplastic-matrix FML based on a self-reinforced polypropylene (SRPP) composite and an aluminum alloy. This FML is manufactured in a simple compression-molding process, allowing it to subsequently be re-shaped according to operational requirements. This paper presents the findings of a study conducted to investigate the mechanical properties for this lightweight thermoplastic FML, investigating its properties in tension, flexure and impact.
