A comparison of the drilling material removal rate of plain GFRP and novel GFRP blended with banana fiber composite

Abstract

The current study aims to investigate the Material Removal Rate (MRR) of a glass fibre reinforced polymer composite with and without natural fillers (novel Grass powder, Banana fibre). The composites were made using the hand layup method. We employed three sets of nine specimens of the three different composites each to measure the MRR in CNC drilling process. Drill diameter, feed rate, and spindle speed were all controlled variables. Using the SPSS tool to analyse the results, a significant value of 0.025 (P0.05) was discovered. The material removal rates of samples with and without fillers were examined and contrasted based on the test results. Compared to regular GFRP, banana fibre has improved drilling properties. Blended banana fibre GFRP. Comparing banana fibre mixed GFRP to plain GFRP and new Grass powder blended GFRP, drilling properties of the former have been found to be greater.
