The shift towards sustainable practices has heightened the focus on natural materials due to their biodegradability and recyclability. This study explores the influence of silicon carbide (SiC) fillers at varying loadings (0%, 20%, and 40% by weight) on the performance of jute/sisal fibre-reinforced epoxy hybrid composites. The work aims to enhance mechanical strength, thermal stability, and structural reliability through the synergistic integration of natural fibres with ceramic reinforcements. Systematic characterisation is carried out following ASTM standards, including tensile, flexural, and thermal analyses, to evaluate the effect of SiC incorporation. Results reveal 20 wt.% SiC offers the most optimised performance, exhibiting tensile strength of 32–35 MPa, flexural strength of 92.17 MPa, and enhanced thermal stability due to uniform filler dispersion and effective stress transfer. DTG analysis confirms higher SiC content shifts the degradation onset (350–420°C) and increased char yield, signifying improved thermal resistance.
