Abstract: This paper investigates the interfacial, tensile, and fatigue properties of a novel smart fiber-metal laminate (FML) based on a nickel-titanium (Ni-Ti) shape memory alloy and a woven glass fiber reinforced epoxy. Initial tests, using the single cantilever beam (SCB) geometry, have shown that this unique system offers high values of metal-composite interfacial fracture toughness. Tensile tests have shown that the mechanical properties of these FMLs lie between those offered by its constituent materials and that their tensile modulus and strength can be easily predicted using a rule of mixtures approach. Tension-tension fatigue tests have shown that the fatigue performance of notched smart FMLs is superior to that offered by the plain Ni-Ti alloy. A subsequent optical examination of unnotched laminates tested to failure under tension-tension fatigue loading has shown that the fracture mechanisms occurring within the Ni-Ti FMLs are strongly dependent on the applied cyclic stress. © 2007 Society of Plastics Engineers.
