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.

Graphene is playing an important role in the enhancement of new composite materials and is capable of enhancing the performance and functionality of many applications. Graphene-reinforced structures are used in nano-sized systems, energy storage devices, automotive and combustible devices, defence system, aerospace systems, medical instruments, biomedical system, and electronics devices. Due to the crucial mechanical behaviour of nano-structures design, the complete understanding of the flexural, buckling, and vibration analysis of various nanocomposite (NC) structures such as beams, plates, and shells have received great attention in recent years. The present article reviews the synthesis techniques of graphene-reinforced nanocomposites (Gr-NCs). The article also discusses the existing micromechanics models to determine the mechanical properties of Gr-NCs. The comprehensive review also presents a detailed assessment on mechanical analysis and applications of Gr-NCs structures. The article further discusses the future scope and technical challenges that may help in the appropriate design and analysis of graphene nanosystems, applicable in the various field of nanotechnology and nanocomposite materials. The purpose of the present review is to critically review the existing development in Gr-NCs and provide the comprehensive overview of Gr-NCs. By reinforcing graphene and its derivatives into the matrix, the resulting composite may enhance the functionality and explore new NCs for of various nanostructures.

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.
