The effect of loading rate on the interfacial fracture toughness of a glass-fiber/polyamide fiber-metal laminates (FMLs) was studied. Impact testing was conducted at 3 m/s using a drop weight impact machine with a striker of mass 2.6 kg. Overall, although the results and differences in failure mode suggest a viscoelastic response in the film adhesive, the outcome is a positive effect on the interfacial fracture toughness.
