Aluminum foam sandwich structure, with the characteristics of light weight and high stiffness, can be used as an excellent structural material.For example, when used as a structural part of a car, its weight is only half that of a steel structure, and its stiffness is increased by 10 times. It is reported that about 20% of the structural parts of a car can use this structure.
1. New building materials:
Aluminum foam is a new type of construction and decoration materials, it has light weight, high specific stiffness, beautiful, not burning, and other advantages, and has sound absorption, heat insulation, electromagnetic shielding and other characteristics.Therefore, aluminum foam can be widely used in the decoration of shopping malls, hotels, stadiums and other venues.
2. Electromagnetic shielding materials:
Due to its excellent electromagnetic shielding performance, aluminum foam can be used for the electromagnetic shielding of telecommunications, electronic instruments, computer rooms and television broadcasting equipment, and can prevent the EMP effect caused by nuclear radiation (the effect can burn semiconductor or produce electronic chaos caused by data transmission loss, and eventually destroy electronic equipment).
3. Insulation materials:
Because its thermal conductivity is low, at the same time has the quality light, the high ratio rigidity, does not burn and so on .can use as the heat insulation, the heat preservation, the cold preservation material and so on.
Impact energy absorbing material: due to its excellent impact energy absorbing performance, it can be used as the protective shell of automobile anti-impact gears and mechanical devices, the safety pad of lift, the interlayer of aircraft shell (shock wave) and the protective layer of space vehicles (space debris can be captured).
