A novel hybrid composite made of glass and jute and reinforced with nanoparticles of copper slag, aluminum oxide, and glass underwent experimental analysis to determine its surface roughness.

Abstract

Aim:This research study is to investigate the surface roughness on the drilled hole surface of glass fibre/jute fibre reinforced polymer composite with and without filler particles Al₂O₃ +glass beads/copper slag. Material and Methods: The polymer composites are fabricated into two groups: Experimental and Control group. The fabrication process used is the hand layup method. The sample preparation and surface roughness measurements were done in accordance with the ASTM-D3039 standard using Mitutoyo make roughness tester.. The statistical analysis was performed using the SPSS v26 Statistical tool. The G-Power used for this process is 80%, α = 0.05 per set for calculating sample size and total sample size is N=40. The surface roughness data was evaluated by using an independent sample t-test.Results: From the experimental results, the mean surface roughness value of 51.1097μm with standard deviation of 0.86734 is noticed in aluminium oxide+glass beads/copper slag filler added composite (Experimental Group) and mean surface roughness value of 55.4955μm with standard deviation of 1.7210 is reported for glass/jute fibre composite without novel aluminium oxide+glass beads/copper slag filler. Using the SPSS v26 software, the significance of the findings was estimated and found to be p=0.002 (p<0.05). Conclusion: Within the limitations of the study, the samples containing   4 wt.% of Aluminium oxide+glass beads/copper slag shows 9% reduction in surface roughness when compared to samples without filler materials which is significant improvement.
