Abstract

This study investigates the mechanical performance of bamboo fibre-reinforced polymer composites (BFRPCs), emphasizing tensile, flexural, and impact properties. The composites were fabricated using an epoxy resin matrix combined with untreated bamboo fibres in varying fibre contents ranging from 25% to 45%, utilizing the hand lay-up method. Among the tested compositions, the composite with 35% bamboo fibre content exhibited the most favorable mechanical characteristics. It achieved the highest tensile strength of 50 MPa, a tensile modulus of 3.2 GPa, and an elongation at break of 5.5%, indicating a balanced combination of strength and ductility. Flexural tests further revealed optimal performance at this fibre content, with a flexural strength of 70 MPa and a modulus of 4.5 GPa. Impact resistance, measured through the Izod impact test, also peaked at 35% fibre content, yielding an impact strength of 7.2 kJ/m². These results confirm that a 35% fibre content delivers the best synergy between matrix and reinforcement, making it particularly suitable for high-strength, impact-resistant applications in automotive panels, construction formwork, and lightweight structural components. The study underscores bamboo’s promise as a renewable and eco-friendly reinforcement, offering a compelling balance of mechanical performance and sustainability. Future research directions include improving fibre–matrix adhesion via chemical treatments and evaluating alternative bio-based or hybrid resins to enhance performance in varying environmental conditions.
