“…This method employs two essential tools: (i) the S/N ratio to assess the quality and (ii) orthogonal arrays to adopt several elements impacting wear simultaneously. From table 4, an L16 orthogonal array was adopted according to the Taguchi design principle [25,[28][29][30][31][32]37]. Minitab statistical software was used to create all of the designs, graphs, and analyses in this study.…”

In this research, carbon fiber and Graphene nanoplatelets (GNP) of different weight percentages of GNP (0, 0.1,0.3, and 0.5 wt.%) reinforced hybrid composites were fabricated via hand layup technique followed by compression molding. For wear analysis to understand the correlation between control parameters (wt.% of filler, normal load, velocity, and sliding distance) and response measurements (weight loss), the design of experiments and analysis of variance (ANOVA) is used. The control variables such as normal loads (5, 10, 15, and 20 N), velocity (1,2,3 and 4 m/s), and sliding distance (200, 300, 400, and 500 m) are selected for the research. It was observed that 0.5wt.% GNP-filled carbon fiber/epoxy composite shows higher tensile and flexural strength than another composite. It has been discovered that adding GNP reduces the wear in terms of weight loss. Scanning electron microscopy (SEM) was used to examine composites' worn surfaces. The analysis concluded that experimental results are closer to optimum results.

This paper evaluates the wear properties of epoxy nanocomposites containing GNP (Graphene Nanoplatelets). In this research, variation of GNP (0,0.1, 0.25, and 0.5 wt.%) were used to make nanocomposites. The hand layup technique was used for the fabrication of different composites. The Taguchi method is used to optimize the wear test and its related characteristics. Analysis of variance is used to understand the correlation between input variables and response measurements. Load (0.5,1.0,1.5, and 2.0 kg) and time (4,6,8, and 10 minutes) are the main variable for exploring wear characteristics for this study. It has been discovered that minimum wear in terms of mass loss and friction coefficient are minimum at 0.5wt.% GNP. Scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX), and RAMAN spectroscopy were used to characterize the wear mechanism. The result shows that the optimized value is closer to the experimental value.

“…Generally, continuous fibers are utilized in developing polymer matrix composite for structural applications, especially in aerospace and transport industries. Due to the usage of continuous fiber, slots and hole making over fibre-reinforced composites is a difficult task to date [9][10][11][12][13]. Machining fibre reinforced composite using conventional technique results in poor dimensional accuracy, fiber pull-out, high operating cost, fibre damage, higher tool wear rate, interlaminate failure, surface damage etc.…”

Influence of reduced graphene oxide addition on kerf width in abrasive water jet machining of nanofiller added epoxy-glass fibre composite

The present study aims to develop a novel hybrid polymer composite with reduced graphene oxide (rGO) as filler and optimize its Abrasive Water Jet Machining (AWJM) parameters for reduced kerf width. The influence of rGO addition on kerf width is analysed in detail along with Pump pressure (bar), Transverse speed (mm/min) and Standoff distance(mm). The experiments are designed based on Taguchi’s orthogonal array techniques in which L27 is adopted for three input parameters at three levels. The influence of each factor is used to identify the significance of selected parameters over kerf width, and it was found that stand of distance has a major effect over kerf width irrespective of rGO %. The addition of rGO filler has a significant effect on kerf width, which decreases with the addition of rGO up to 0.2% and kerf width increases for further addition of rGO.
