Abstract
This study investigates the effects of thermal conditioning on the mechanical and thermal properties of banana-glass fibre hybrid composites, focusing on their tensile, flexural, impact strength, and thermal conductivity. Hybrid composites were fabricated with varying banana-to-glass fibre ratios of 70:30, 50:50, and 30:70 using a hand layup technique, followed by thermal conditioning at 60°C, 80°C, and 100°C for a specified duration. Results highlight that the 50:50 composite treated at 80°C exhibited the highest tensile and flexural strengths, demonstrating a 22% and 25% improvement, respectively, compared to untreated composites. This enhancement is attributed to the balanced distribution of glass fibres and the thermal stabilization of banana fibres. Impact strength peaked at 100°C, with the 30:70 composite showing a 30% increase, indicating improved toughness due to better fibre-matrix adhesion. Thermal conductivity analysis revealed that the 50:50 composite thermally conditioned at 80°C achieved the lowest thermal conductivity, highlighting its potential as an efficient insulator. Composites treated at 100°C, while exhibiting improved impact strength, showed signs of fibre degradation, adversely affecting tensile and flexural performance. These findings suggest that thermal conditioning at 80°C optimally enhances the mechanical strength and insulation properties of the hybrid composites while minimizing thermal degradation. The study concludes that these composites, particularly the 50:50 ratio treated at 80°C, are suitable for engineering applications requiring a balance of strength, toughness, and thermal insulation.
