It is well known that the performance of the material depends on its scope of application: spare hole foam aluminum is a kind of composite materials of gas phase and solid phase separated from each other, it makes the continuous solid aluminum metal characteristics (such as strength, high temperature resistant and dispersed in the gas phase gas characteristics (such as damping, heat insulation, sound, can reduce and shielding, etc.) organic combination together, making them the various performance (even apparently contradictory performance) with the combination of new materials.Main wheat performance in the following aspects.


 
Energy absorption properties：
From the quasi-static compression curve of closed-cell aluminum foam material, it can be found that there is a long -section stress platform, which enables aluminum foam to keep the stress basically unchanged within a large strain range, and convert the applied energy into the work done by the material's deformation.It indicates that foamed aluminum has excellent energy absorption characteristics.According to the literature, foamed aluminum also has a good performance in energy absorption.Therefore, aluminum foam material is an ideal choice for preparing energy absorbing materials such as buffers and energy absorbers, which can be applied from the anti-impact baffle of cars to the landing gear of spacecraft.In addition, the closed-cell aluminum foam material has been successfully used in elevators, transporter safety pads, high-speed grinder protective cover energy absorption lining and so on.
