Fabrication and diFFerent characterization oF Graphene nano platelets reinForced epoxy nano composites in this research, graphene nanoplatelets (gNP) reinforced epoxy nano composites were fabricated via magnetic stirrer and ultra sonification assisted hand layup method. the impact of different weight percentage of gNP (0, 0.25, 0.50, and 1.0%) on different characteristics of nano composites was evaluated. the microstructure analysis of developed nano composite was determined by Field emission scanning electron microscopy. it was examined that epoxy nano composites containing 0.5 wt.% gNP have the highest tensile, flexural, and impact strength compared to neat epoxy. the reduction in tensile and flexural strength is achieved at 1% of gNP. Adding more nanofiller to a certain limit causes non-uniform dispersion and agglomeration of nanoparticles, which results in a reduction in properties. the 1% gNP reinforced nano composite has the highest value of shore hardness.

In the pursuit of sustainable and high‐performance materials, this study presents a groundbreaking approach to enhance the mechanical properties of glass fiber‐reinforced polymer composites. Railway waste provides an unexpected source of recycled glass fibers (RGFs), which, when combined with bamboo fibers (BFs) and nano SiO2 in a resilient epoxy matrix, unleashes a transformative synergy. The epoxy‐SiO2 matrix ratio was kept constant, that is,70% by weight while varying the ratio of RGF and BFs weight. The experimental results demonstrated notable improvements in mechanical properties. Specifically, a 36.92% increase in tensile strength was observed with an RGF and BF ratio of 20:10. Flexural strength exhibited a substantial enhancement of 44.67%, and impact strength increased by 31.28% at a ratio of 15:15. The composite achieved a remarkable 42.64% improvement in hardness, while attaining the lowest density value of 0.862 at a ratio of 25:05.Water absorption tests, conducted in both distilled and saline water, provided insights into the material's resistance to environmental conditions. The morphological and dispersion behaviors of the prepared composites were analyzed using advanced characterization techniques, including field‐emission scanning electron microscopy (FE‐SEM) to study the orientation, shape, and size of fibers and particles, bonding between the fibers and matrix, defects, voids, etc. Combined with energy dispersive x‐ray spectroscopy (EDX), FESEM allows for elemental analysis, helping to identify and quantify the chemical composition of different phases within the polymer composite.

Polymer nanocomposites have been gaining attention in recent years. The addition of a low content of nanomaterials into the matrix improves mechanical, wear, thermal, electrical, and flame-retardant properties. The present work aimed to investigate the effect of graphene and hexagonal boron nitride nanoparticles on Kevlar and hybrid fiber-reinforced composites (FRP). Composites are fabricated with different filler concentrations of 0, 0.1, 0.3, and 0.5 wt.% by using a hand layup process. Characterizations like tensile, flexural, hardness, and impact strength were evaluated separately, heat deflection and viscosity properties of the epoxy composites. The dynamic viscosity findings indicated that a higher concentration of filler material resulted in nano-particle agglomeration. Graphene filler showed superior properties when compared to hexagonal boron nitride filler. Graphene showed optimum mechanical properties at 0.3 wt.%, whereas the hBN filler showed optimum properties at 0.5 wt.%. As compared to Kevlar composites, hybrid (carbon–Kevlar) composites significantly improved properties. As compared to graphene-filled composites, hexagonal boron nitride-filled composites increased scratch resistance. Digimat simulations were performed to validate experimental results, and it was observed that hybrid fabric composites exhibited better results when compared to Kevlar composites. The error percentage of all composites are within 10%, and it was concluded that hybrid–graphene fiber composites exhibited superior properties compared to Kevlar composites.
