The study presents the municipal solid waste mixed polymer composite based diapers waste (MSWPC-DW) for partition panel application. The focus of this study is to determine the optimum ratio of the MSWPC-DW which is suitable for partition panel application. The use of diapers waste as reinforcement materials in epoxy matrix is to produce a partition panel that has sustainable properties and environmentally friendly. The preparation of sample involved grinding process of diapers waste of different ratio with 0.1, 0.2, 0.3, 0.4, 0.5 and 0.6 into small particles sizes and mixed with epoxy resin and hardener, then put into aluminium mould with casting method for curing process for 24 hour at room temperature (24 ± 2ºC). The hardened samples named as MSWPC-DW then subjected to physical and mechanical properties testing. The MSWPC-DW ratio of 0.4 achieved the second lowest density of 1.05 g/cm3 and an average porosity of 13.7%. The SEM image 0.4 MSWPC-DW shows less number of voids exhibiting excellent good dispersion of filler and the resin matrix. The higher numbers of breaking fibres of the diapers waste in the ratio 0.4 MSWPC-DW indicate the higher mechanical strength of the composite. The tensile strength test showed that ratio 0.4 MSWPC-DW achieved the highest tensile strength and stiffness elasticity at 6.11 MPa and 76.06 MPa, respectively. It is similar to the flexural strength test, ratio 0.4 MSWPC-DW also indicated the highest deflection of 34.82 mm and the highest maximum strength at 22.92 MPa. Ratio 0. 4 MSWPC-DW recorded the highest impact strength of 25.65 kJ/m2 and highest compressive strength at 12.09 MPa. In terms of sound absorption coefficient (SAC), MSWPC-DW ratios of 0.5 and 0.6 achieved the highest SAC of 0.93α at a frequency of 1250 Hz, while the ratio of 0.4 obtained the second highest SAC of 0.85α. In summary, these results show that ratio 0.4 of MSWPC-DW were the best in fabricating the partition panel.
