The primary aim of this study is to improve the compressive strength (CS) of the particulate composites. This is accomplished by mixing a polymer base with various additives, such as sawdust (SD), aluminium (Al), and iron (Fe) particles. The necessary composites are produced by adding varying weight percentages (wt%), i.e., 5, 10, and 15% weight-by-weight (w/w) of the additive compounds. In this study, the researchers employed a hand-moulding approach to produce a compressed composite. The experimental findings indicated improved CS value of some of the composites. These findings were influenced by factors such as the type of additives, density, wt% of the additive, and the properties of particle dispersion within the polymer. It was noted that when 15% (w/w) of Fe particles were added to the compound, the CS value improved by 23%. Despite an excellent dispersion of particles within the polymer, a minimum improvement in CS of 12% was observed after the addition of 10 wt% of SD particles.
