Fiber metal laminates (FMLs) were initially developed to increase the fatigue and damage tolerance of monolithic metallic structures in the aerospace industry. Adding layers of glass-fiber-reinforced polymer (GFRP) between thin aluminum sheets (0.2mm to 0.5 mm) lead to a new structural material with significantly improved fatigue characteristics, and finally to the industrial application of GLARE (glassfiber-reinforced aluminum laminate) in the Airbus A380. Compared to monolithic aluminum, GLARE shows a significantly higher tolerance to fatigue and damage due to the layered architecture.
