Visit Prof. Rossmanek

Prof. Rossmanek (second from the left) visited our group to discuss a possible collaboration between the University of Newcastle and the University of Applied Sciences Stralsund. Prof. Rossmanek has been driving the development of Formula SAE in Germany and will support img_20161206_125017this year’s event in Melbourne as a judge.

Visit Prof. Vesenjak

In the framework of an ongoing collaboration with the University of Maribor (Slovenia) Prof. Matej Vesenjak (on the right) visited our research team in November 2016. Work was focused on the dynamic testing of metallic foam material and the creation of an editorial for a special issue in Materials. matej

On the compressive behaviour of high porosity expanded Perlite-Metal Syntactic Foam (P-MSF)

Our paper entitled “On the compressive behaviour of high porosity expanded Perlite-Metal Syntactic Foam (P-MSF)” has been accepted for publication in the Journal of Alloys and Compounds 691 (2017) 690-697:

A high porosity Perlite-Metal Syntactic Foam (P-MSF) is produced by the pre-compaction of a packed bed of expanded perlite particles prior to counter gravity infiltration with molten aluminium. The density of the resulting high porosity (>70 vol%) syntactic foam is in the range of 0.72e0.98 g/cm3, depending on the particle pre-compaction pressure and the number of compaction steps. Compressive testing is carried out following the ISO 13314 standard to characterise the mechanical properties of this novel material. Furthermore, micro-computed tomography scans are performed in order to investigate its mesostructure. The geometrical analysis revealed that the densification procedure generates a porosity gradient in the direction of the compressive force. This gradient is found to affect the deformation mechanism and thus the mechanical properties of high porosity P-MSF.
