Analysis of Aluminium Foam Pore Size by Computed Tomography

Aluminium foams are highly porous material whose properties are highly dependent on the shape and size of the pores. Production processes are still not perfected, resulting in pores of uneven shape and size, which worsens their mechanical properties. In order to gain insight into the internal structure of foamed aluminium, i.e. to find out the arrangement of the shape and size of the pores, the sample needs to be cut, which actually leads to its destruction and the impossibility of conducting further mechanical tests. To avoid this, analysis of the arrangement and size of the pores is performed using computed tomography (CT), which involves scanning the sample using X-rays to obtain a three-dimensional model of the foam. This paper describes the procedure of scanning aluminium foam by computed tomography as well as cross-sectional analysis of a threedimensional model.
