Abstract

Foamed materials in general, and aluminium foams in particular, demonstrate a number of interesting properties due to their porous structure, which makes them usable in a wide range of applications. The possibility of absorbing the energy is one of the most interesting properties of foams. The use of lightweight porous materials with high specific strength has attracted much interest in the transportation industry in order to improve safety. Recently, foamed aluminium has frequently been used in various absorbers of kinetic energy (buffers of automobiles, trains, trams). This paper studies the influence of reinforcement in the form of steel rods on compression behaviour of aluminium foams.
