Graphene as a stimulus for mechanical strength in glass-fiber reinforced polymers composite

Abstract

Purpose The purpose of this paper is related with the comparative study between graphene-based glass fiber–reinforced polymer composites and without graphene composite on polymer matrix. The current study explains the result of amalgamation of 4 Wt.% graphene oxide (GO), in comparison to without graphene, on the mechanical strength of glass fiber/epoxy (GE). Design/methodology/approach A hand layup technique is used for the experimental study. For this, chemical synthesis process is approached based on Hummer’s theory. For mechanical testing of glass fiber–reinforced graphene composites and without graphene composites, American Society for Testing and Materials-3039 (ASTM3039) standards was adopted. Furthermore, comparatively, composites were characterized by field emission scanning electron microscopy. Findings Reinforcement of 4.0 Wt.% GO in epoxy matrix material showed 7.46% and 12.31% improvement in mechanical strength and elongation, respectively. Scanning electron microscopy results showed the influence of graphene cumulations in the failure of GO-reinforced GE (GO-GE) composites. Originality/value The inimitable things of graphene grounded nanofillers have encouraged in the world of material for their thinkable manipulation in glass fiber polymeric composites. In this work, for the first time, graphene is used as nanofiller in glass fiber epoxy coatings, and their fractography study is investigated.

Fabrication and characterization of graphene oxide and glass fiber‐based hybrid epoxy composites

“…They reported that at 0.25 wt% loading, the elastic modulus was increased by 13% and strength by 75%. Dwivedi et al [24] prepared with and without graphene GFRP composites and concluded in their study that the fortification of 4.0 wt% of GO in epoxy matrix material showed improvement in mechanical strength and elongation by 7.46% and 12.31%, respectively. Gara et al [25] used exfoliated GO to prepare GF/epoxy composite to enhance the mechanical properties of the composite.…”
