Abstract

This study investigates the mechanical behaviour and water absorption characteristics of bagasse fibre and groundnut shell particle (GSP)-reinforced hybrid composites using a phenol-formaldehyde (PF) resin matrix. Varying weight fractions of GSP (5%, 10%, 15%, and 20%) were incorporated into the composites, with bagasse fibre content kept constant at 30% by weight. Tensile, flexural, and impact strengths were measured, and the water absorption behaviour was evaluated following ASTM standards.The results indicated a decrease in tensile strength as GSP content increased, with the highest value of 45 MPa observed at 5% GSP, and the lowest value of 32 MPa at 20% GSP. In contrast, flexural strength improved with increasing GSP content, reaching 70 MPa at 20% GSP compared to 55 MPa at 5% GSP. Similarly, the impact strength increased from 8 J/m at 5% GSP to 12 J/m at 20% GSP, attributed to the crack-arresting ability of GSP.Water absorption tests revealed that composites with higher GSP content absorbed more water, with the 20% GSP composite showing a water absorption rate of 6.8% compared to 2.5% for the 5% GSP composite after 72 hours. Moisture exposure led to significant reductions in mechanical properties, particularly in tensile and flexural strengths, where reductions of up to 20% and 20%, respectively, were observed at 20% GSP. Impact strength, however, showed a lesser reduction of around 10%.The study concluded that a 10% GSP content provided an optimal balance of mechanical performance and water resistance, making it suitable for applications such as automotive components and construction materials.
