Abstract

In this work, aluminium foams with modified geometry were successfully fabricated by a combination of dense and porous structure. The main objective of this study was to determine the initial physical properties of aluminium foam with modified geometry in terms of density, porosity and morphology. Three different NaCl space holder sizes ranging from 1 mm to 3 mm were sieved and used to replicate the final pore size of aluminium foam. The samples were successfully produced through the casting replication process. After densification, samples underwent water leaching in an ultrasonic bath to completely remove the space holder. Results showed that the porosity of the aluminium foam increased from 50 – 62% when the size of space holder was increased from 1 mm to 3 mm. The morphology displayed clearly an integrated modified geometry between dense and inter-connected porous structure which is beneficial for applications that require combination properties of structural and functional application.
