“…A motive for that, especially in the 21 st -century, is a rapid increase in air pollution and global warming, which is directly in correlation with the greater use of fossil fuels. Weight reduction is one of the ways to reduce fuel consumption, and metal foams stand as the material with great potential for that [3,4]. Tubular structures are the most commonly implemented and recognized energy-absorption devices in automotive industries.…”

In this study, aluminum foams reinforced with different steel elements were produced by the AluLight process. The master alloy AlMgSi0.6 was used as the matrix material, titanium hydride (TiH2) powder was used as a foaming agent, and steel wire, cylindrical steel mesh and flat steel mesh were used as reinforcing elements. Reinforcements were placed inside the mold, along with the precursors, and samples were manufactured by gas releasing particles in a semi-solid state. To examine the effect of the reinforcements on specific energy absorption, quasi-static uniaxial compression tests were carried out, with a constant separation rate of 1 mm/s. From the tested results, the energy absorption per unit volume and specific energy absorption efficiency were calculated and then also statistically evaluated. The results showed that examined shapes of reinforcements affect differently specific energy absorption and its efficiency, compared to non-reinforced aluminum foams. The best result obtained was with cylindrically shaped steel mesh.

“…By changing the parameters of production, properties of porous are also being changed [8]. Many researches had been done experimentally about mechanical behaviour of aluminium foams, but there are some gaps that need to be filled by varying parameters and testing methods for energy absorption behaviour [9]. Way to improve energy absorption properties of aluminium foams is to have a higher relative density or the bonding between extrusion/foam.…”

The Influence of Applied Force on Aluminium Foams Energy Absorption

Aluminium foams are composite materials made of aluminium or, frequently, of aluminium alloys. They have cellular structure consisting of metal matrix and gas filled pores and are occasionally produced with extrusion technologies. One of the ways to produce foamed aluminium is to mix Al powder with a blowing agent. That way, the blowing agent releases gas at higher temperatures and at the end, with different technologies and methods, such as extrusion technology, mixture is compacted. Nine samples of aluminium foams were produced from the following precursor Alulight AlMgSi0,6 titanium hydride TiH2 (cylindrical shaped, dimension ø42 × 79,5 mm, relative density between 0,186 and 0,268. Aluminum foam investigated in this work had closed cells where quasi-static uniaxial compression was used to determine how applied force influences aluminium foams energy absorption properties. For energy absorption it is important to determine the critical force that will activate the maximum amount of absorbed energy. The dependence of energy absorption capacity and energy absorption efficiency on the compressive force was investigated, and then the obtained results were compared for different samples. By increasing the force, the energy absorption capacity of higher density foams increases faster. The energy absorption efficiency at low forces does not depend on the density of the samples but with increase of force, higher density foams become more efficient.
