Comparative investigation of impact strength and water absorption characteristics of novel grass powder blended GFRP and jute fibre blended GFRP with plain GFRP

This study examines the drilling characteristics on GFRP/Banana fiber composite without and with use of Al2O3 filler used in fabrication. of an epoxy-based glass fiber reinforced polymer with and without filler made of banana fiber and aluminum oxide powder. hand layup technique employed in fabricating Three kinds of polymer composites. Pre-test G power for testing was set at 80%, Alpha was set at 0.05%, and CL was set at 95%. This number of samples for each group was then determined. Three groups of nine samples each are used to experiment at CNC and MRR performance evaluated. Controlled variables were feed, drill diameter and spindle speed. The test findings were examined and contrasted using a one-way ANOVA test. The end outcome is MRR. To compare the rates of samples with and without fillers, test data were employed. Software called SPSS V16 was used to determine how significant the results were. A significant level of p0.05 was obtained from the statistical value analysis. The machinability of proposed composite is found good in terms of MRR. That MRR 9.89% fpund excess than machining of plain GFRP. In a similar vein, it was discovered that machining of alkaline-treated glass fiber/banana fibre composite found increase of 14.99% than plain GFRP laminate.

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.

“…Speed of the spindle (m/min) Different reinforcing ratios of fly ash to AL6061 were observed to affect the surface roughness of the fly ash reinforced AL6061 composite [16]. Using the Taguchi approach, the surface roughness of new Al/fly ash composites was determined in this study [17][18][19][20][21][22]. No contrary study analysis was found in the surface roughness findings.…”

The present investigation is the influence of limited reinforcement of fly ash (5 wt%) effects on surface roughness. In this regard, the fly Ash reinforced aluminium alloy (AA7475) composite was prepared and machined and measured the surface roughness to compared to aluminium alloy (AA7475). The sample size is 32 (16 for each tool) with 95% CI pre-test power 80% was used. The surface grinding operation is used to remove surface abnormalities. These pieces are machined in specific contour milling and are performed with different tools. Machined specimens are tested using a profilometer for calculating surface roughness and it was performed according to ASTM D3039 standards. The findings suggested that the plain aluminium alloy (AA7475) had a surface roughness of 0.51 mm and the composite aluminium alloy (AA7475) reinforced with 5 wt% fly ash had a surface roughness of 0.38 mm. The statistical value analysis yielded a significance value of 0.034 (p>0.05), indicating that there was substantial variation across the groups. In this research investigation, it was found that the surface roughness of a composite made of a 5 wt% fly ash augmented aluminium alloy (AA7475) was 32.27% lower than that of a plain aluminium alloy.
