Abstract
Nanocomposites can be used as an acoustic panel to adsorb noise. The aim of this study was to evaluate: (1) acoustic, (2) physical, and (3) mechanical properties of agro-environmental nanocomposites. To prepare the nanocomposites, wood flour, PVA glue, and aluminum nanoparticles (between 1 and 4 %) were hardly mixed and heated at near 220 °C for 120 min. In the next step, sound absorption coefficient, transmission loss, water absorption percentage, thickness swelling percentage, density, flexural strength, flexural modulus, tensile strength, and tensile modulus of nanocomposites were measured. This study showed that the increase in nanoparticle percentage led to the increase in flexural strength, flexural modulus, water absorption percentage, thickness swelling percentage, density, and sound absorption coefficient. But, the increase in nanoparticle percentage led to the decrease in tensile strength, tensile modulus, and transmission loss. The authors think that the nanocomposites are suitable as an agro-industrial nanocomposite to reduce noise.
