Abstract :The efficacy of reinforcement of polyester resin matrix composites with hard ceramic particles for optimal performance was studied. 5-25 wt. % of silicon carbide, millscale, and magnesia particles were applied in reinforcing unsaturated polyester resin matrix by mould casting and the microstructural and mechanical characteristics of the composites were evaluated. There was uniform distribution of silicon carbide, millscale, and magnesia particles in the polymer composites matrix from the scanning electron microscopy insert ignore into journalissuearticles values(SEM); result. The highest mechanical properties in terms of ultimate tensile strength insert ignore into journalissuearticles values(73.75 MPa);, flexural strength insert ignore into journalissuearticles values(74.89 MPa);, hardness insert ignore into journalissuearticles values(98.76 BHN);, and impact energy insert ignore into journalissuearticles values(24.85 J); was exhibited by the hybrid composite at 15 wt. % reinforcement. This shows the efficacy of hybridisation and the high potential of the composite for wider applications.
