Aluminum alloy plate is an important structural material for aerospace vehicles, mainly used for fuselage skin, wing and stabilizer skin, fuselage partition frame, oil tank and other structures. Through the application of aluminum alloy composite materials, the shell materials on aerospace vehicles can reduce the density by 5% - 7%, the material stiffness by 7%, and the weight by 10%, so as to improve the fuel efficiency. At the same time, because of the corrosion resistance, good fatigue resistance and damage tolerance of aluminum alloy materials, and the extension of inspection interval, the maintenance cost of spacecraft can be reduced.
