The primary objective of this study is to measure the surface roughness of a laminate made of Banana fibre epoxy reinforced with a stainless steel wire mesh. Composite without Stainless Steel reinforcement is made using 5 plies of bidirectional Banana fiber fabric (B-B-B-B-B) and composite laminate with reinforcement is made using bidirectional sustainable banana fiber fabric and Stainless Steel mesh stacked in sequence (B-SS-B-SS-B). This research is aimed to achieve better low surface roughness with the addition of Stainless Steel mesh reinforcement. A total of 20 tests were conducted. The number of samples was decided with a G power of 80%. To analyze the surface roughness, T-independent tests were done using the SPSS statistical software tool. According to the experimental data, Group 1, banana fiber-reinforced epoxy composite laminate had an average of 2.9530 (µm) while Group 2, composite laminate of banana fiber reinforced with stainless steel wire mesh had an average of 1.4249 (µm). The surface roughness testing is done with the Mitutoyo surface roughness test setup as per (the SJ-410) standard. The mean-variance of surface roughness between Group-1 and Group-2 is determined to be significantly different with “p = 0.001 (P < 0.05) based on T-test” statistical analysis. The samples from the experimental and control groups’ mean surface roughness the samples from the “banana-fiber epoxy composite” laminate with “Stainless-Steel wire mesh” group have samples with an average surface roughness of 43% more compared to the banana fiber epoxy composite laminate without Stainless Steel wire mesh group.
