Multi Functional Behavioural Analysis of Al-SiC Metal Matrix Composite Foam Produced by (TiH2-CaCO3) Dual Foaming Agent

Aluminium alloy composite foams reinforced by 5% vol. SiC particles were fabricated with melt foaming route using TiH2 -CaCO3 dual foaming agent. The compressive modulus and strength of two different relative density aluminium foams were investigated experimentally. An empirical relationship was established between normalized change in density and strain, using experimental data of compression tests up to different strain levels. Sound absorption property of the developed material was found out by impedance tube method. Acoustic test results indicate the potential of the material as sound absorber.Copyright © 2010 by ASME
