An Experimental Investigation on the Acoustic and Thermal Properties of Copper Reinforced Sustainable Foam

Abstract

Organic foams with different proportions of copper powder are fabricated using a general mixing process. The physical and chemical properties and the sound abortion coefficient of these foams are investigated. The FTIR test results indicate the presence of different organic functional groups in the flexible organic sustainable foam; Acoustic shielding test compares the sound absorption coefficient; Lee disc method used to find the thermal shielding (Thermal Conductivity) of the samples fabricated. The sound absorption coefficient is found to increase with increase of copper percentage in the foam. The mechanical behavior is approximately same for the reinforced foams with different percentage of coppers and is similar to that of unreinforced foam. The thermal conductivity is found to increase with the increase in the percentage of copper in the foam thus unreinforced foam has better thermal shielding property.
