Abstract:Fibre Reinforced Metal Laminates (FRMLs) are used widely for aeronautical industry with excellent mechanical properties such as high specific strength, specific Young`s Modulus, high damage tolerance and high resistance to fatigue crack growth. Nowadays, metal alloy plates and fibres being used in FRLMs are almost aluminium alloy plates and glass fibres. As we know that the density of magnesium alloy is only 2/3 of aluminium alloy and the tensile strength of carbon fibre is higher than glass fibre. If replacing aluminium alloy and carbon fibres with magnesium alloy and glass fibres , carbon fibre-metal laminates based on magnesium alloy will be obtained. The tensile and fracture toughness tests were done to verify that the tensile and fracture toughness properties of carbon fibre-metal laminates based on magnesium alloy are better than glass fibre-metal laminates based on aluminium alloy.
