Sažetak

Metals in foam shape, the so called metallic foams or metal foams, consist of a base metal material with a certain amount of gas bubbles dispersed throughout the body of the material. These bubbles are actually foam cavities or cells. Metal foams are low-density materials with high strength and rigidity, as well as with good damping capacity. Therefore, their application in the lightweight structure concepts is the object of intensive research. It is possible to join such elements by welding or by screw fastening, and this paper presents the results of researches into the drilling process of closed cell aluminium foam samples. They are produced by the production method of indirect foaming by means of an AlSi12 precursor. The axial force in aluminium foam drilling is established in dependence on relevant drilling process parameters.
