Abstract

The main aim of this work is to determine the physical and mechanical properties of composite materials based on different filler types made from different raw materials (sugarcane bagasse, compost, peat moss, vermiculite and activated carbon) by using the TOPSIS-Taguchi model to optimize combination of filler mixture proportion constituents towards enhancing composite properties. Water absorption, density and void were the measured physical properties; tensile strength and elongation were the analyzed mechanical properties. The results indicate that the highest value of the water absorption was 30%, while the lowest was 15%. The density ranged from 0.616 to 0.711 g cm-3 for all treatments under study. The highest value of the void (2.8%) was found with experiment run number 6, while the lowest value of the void (1.0 %) was found with experiment run number 2. The tensile strength ranged from 12.72 to 13.92 MPa for all treatments under study. The elongation ranged from 10.73 to 12.50 % for all treatments under study.  The seventh experimental set was judged as the best composite from the analyzed properties perspective for TOPSIS composites ranking based on the Taguchi design of the experiment.
