Dampers

The special inner structure of porous aluminium has high shock strength and static loads. In addition, perfect damper properties of PCA are describes as follows: the material resistance to external input smoothly increases with larger deformations, i.e. the inner structure destructs and becomes denser. PCA details are used for protection of transport vessels during transportation of dangerous goods by automobile and railway traffic. Damper elements prevent vessel damage in the event of emergency. Materials analogous to porous aluminium are widely used for life-saving devices of high-speed trains.
