The present research aims to develop sound-insulating materials by utilizing recycled plastic (recycled high-density polyethene-rHDPE) and waste jute fabric (WJF) through the compression molding technique. Two configurations (Neat rHDPE and rHDPE+WJF composite) of sheets were developed. The effect of the sandwiched WJF (10% by wt.) layer in the rHDPE matrix on sound insulation property was studied. The prepared sheets were thoroughly characterized for their properties related to sound insulation, i.e., density (ASTM D792-20), tensile strength, and modulus (ASTM D638-14). The sound transmission loss (STL) of the developed sheets was measured as per ASTM-E2611-17 using a four-microphone impedance tube setup. The developed sheets of neat rHDPE and rHDPE+WJF composite sheets exhibited a density of 974 and 998 kg/m3, respectively. However, the rHDPE+WJF composite sheet possesses 18.24 and 46.52% higher tensile strength and modulus than the neat rHDPE sheet. Moreover, both developed sheets demonstrated excellent sound insulation properties (average STL of 49.01 (rHDPE) and 50.07 dB (rHDPE+WJF composite)). [ABSTRACT FROM AUTHOR] |
