Abstract

This study presents a novel approach using response surface methodology to systematically analyse the impact of incorporating silicon carbide (SiC) and aluminium oxide (Al2O3) into basalt and glass fiber-reinforced epoxy composites, which is a relatively under-explored area in composite material research. The project seeks to investigate the tensile strength, flexural strength, impact energy and fatigue life of the composite resulting from the integration of these ceramic particles. The composites containing 6% SiC and 1% Al2O3 exhibited excellent performance. The L7 samples containing 6% SiC and 1% Al2O3 exhibited highest values of tensile strength (167.43 N/mm2) and moderate flexural strength (154.87 N/mm2). It is worth noting that composites containing L7 (6% SiC and 1% Al2O3) had the maximum recorded impact energy and fatigue life, highlighting the synergistic effects of the hybrid reinforcement. This composite material is highly suitable for the fabrication of boat hulls and decks used in marine industry.
