Abstract:The present investigation aims to develop epoxy-based composites reinforced with banana fibre (5 mm length) and evaluate their various properties. Different sets of composites were fabricated via a simple hand lay-up method with fibre loadings of 0, 2.5, 5, 7.5, and 10 wt. % to investigate their performance. Findings indicate that increasing fibre content reduces the composite`s density, while water absorption increases with higher fibre percentages. ; Banana fibre composites with 7.5% exhibited the maximum tensile, flexural, and impact strengths, with values of 33.1 MPa, 55.6 MPa, and 31.7 kJ/m2, respectively. On the other hand, composite specimens with 10 wt.% fibre loading resulted in maximum tensile modulus (3124 MPa), flexural modulus (3583 MPa) and Barcol Hardness Number (33). The addition of natural fibre improves the wear resistance of the material. ; The minimum specific wear rates reported are 2.37 x 10-4 mm3/Nm for minimum normal load when measured at varied normal load and 1.93 x 10-4 mm3/Nm for maximum sliding velocity when measured at varied sliding velocity. Scanning electron microscopy morphological analysis of abraded samples showed micro-cracks, micro-plugging, and fibre debonding on the surface. The AHP-TOPSIS multi-criteria decision-making technique determined that composites with 7.5 wt.% fibre loading offer the optimal balance of mechanical strength and wear resistance, making them highly suitable for structural and tribological applications.
