Acoustic and Thermal Behavior of Low Density Wheat Straw Particle Board

Wheat straw being a versatile material was used to make particle boards of different densities to make its use in interior applications for thermal and sound absorption. Efforts were made to optimize the process parameters to make boards of low densities 300, 400 and 500 kg/m3 and the boards manufactured were been tested for sound absorption coefficient as per Indian standard 10420-1982 and thermal conductivity as per Indian Standard 3346-1980. The manufactured boards were also examined for the physical properties as defined in IS 3129-1985. The study reveals that the thermal conductivity of the wheat straw particle board increases as density increases with linear trend equation Y = 0.0003X + 0.0177 and coefficient of determination (R2) 0.9982. Sound absorption coefficient values of 300kg/m3& 400kg/m3 density boards were conforming the requirements of IS 3129. The boards of density 400kg/m3 and 500kg/m3 meets all the requirement of physical and mechanical properties of IS 3129.
