The heat shielding and thermal stability capability of ceramic fillers brings it to the forefront for utilisation in polymer composites for thermally variable applications. The present work focusses to study the physical, mechanical and thermal behaviour of ceramic filler (SiC) in glass fiber reinforced hybrid polymer composites. During the investigation, different weight percentages of SiC filler (0–40 with step of 5) was added with glass fiber to fabricate epoxy based composites using hand layup technique. The tensile, flexural, impact strength, hardness of both types of the composites were determined. Further thermogravimetric analysis and thermal conductivity test was performed to study the effect of ceramic filler and glass fiber on the thermal behaviour of the developed composites. The experimental thermal conductivity values of composites were compared with those of analytical models. The experimental results indicate varied rate of deterioration of tensile and flexural strength of the hybrid composites with respect to the SiC filler content. The maximum tensile and flexural strengths obtained were 312.25 MPa, 376.91 MPa respectively for SiC (0 weight %) -Glass Fiber (30 weight %) hybrid composites. However, the impact strength and hardness of the composites enhanced due to the incorporation of SiC ceramic fillers. The optimum impact strength of 76.48 MPa was obtained for SiC (30 weight %) -Glass Fiber (30 weight %) hybrid composites. The inclusion of SiC ceramic filler enhanced the thermal stability and conductivity of epoxy-based composites. However, the hybridization of SiC filler with glass fiber further improved the thermal properties of the composites. The optimum experimental thermal conductivity value of 0.9906 W/mK was obtained for SiC (40 weight %) -Glass Fiber (30 weight %) hybrid composites. The thermal stability of the composites enhanced with increase in SiC ceramic filler content. The microscopic analysis of the developed composites was carried out to ascertain deformation mechanisms of under tensile, flexural and impact loading.
