Abstract
The aluminum foam is a new class of material with low density, better corrosion, wear resistance and low thermal expansion. Their applications are in lightweight structural components, shock or sound absorbing products. The foam agents used in this process are calcium carbonate and magnesium carbonate powder. The composite aluminum foam structure is fabricated by bottom pouring stir casting furnace. The results show the energy absorption capability of the foam structures is much greater than the energy absorbed by the aluminum structure. The main aim of this project is to reduce the density and cost of the metals and to produce higher foaming by adding two blowing agents namely calcium carbonate and magnesium carbonate. These foaming materials are applied in structures and supportive columns of buildings. The results show that the fabricated component has a lower density and good mechanical properties with low-cost foaming materials.
