The two types of FML used in the study were based on primary contact bonding at the bi-material interfaces and secondary adhesive bonding. It was observed that deformation and fracture of the adhesive layer were responsible for higher interfacial fracture energy. Results show that the heating-stamping manufacturing process has potential for high volume production of low cost thermoset-based FMLs with a tough ethylene-based thermoplastic film adhesive at the bi-material interface which ensured high interfacial fracture toughness.Keywords: Adhesives; Aluminum alloys; Cantilever beams; Crack propagation; Cracks; Deformation; Delamination; Fiber reinforced materials; Fracture testing; Fracture toughness; Interfacial energy; Polyamides; Delamination resistance; Fiber-metal laminates (FML); Int200410.1023/B:JMSC.0000021464.13845.792015-12-12
