Effect of Graphene Oxide-Boron Nitride-Based Dual Fillers on Mechanical Behavior of Epoxy/Glass Fiber Composites

Abstract

Graphene and its derivatives have excellent properties such as high surface area, thermal, and mechanical strength, and this fact made the researchers promote them as the possible filler material for fiber-matrix composite. The current research deals with validation on the effect of graphene oxide boron nitride filler over mechanical and thermal stability of epoxy glass fiber polymer matrix composite. The objective of this experimental investigation is to develop glass fiber reinforced polymer composites with hybrid filler addition. The matrix material selected is epoxy resin, whereas the glass fiber is selected as reinforcement, while boron nitride and graphene oxide are chosen as fillers. Compression moulding methodology is followed to develop the composites with the constant percentage of fiber loading, graphene oxide filler, and varying boron nitride content from 0 to 3 wt.% at an equal interval of 1 wt.%. The developed composite is analyzed for mechanical properties, and the fractured surface is analyzed through the scanning electron microscope. The addition of hybrid fillers enhances the fiber-matrix bonding strength and improves the thermal and mechanical properties up to a specific limit. Thermal gravimetric analysis was conducted to understand the thermal behavior of composite. The results revealed that the addition of filler improved the thermal stability of the composites.

Insights into the large‐size graphene improvement effect of the mechanical properties on the epoxy/glass fabric composites

“…[1][2][3] As thermosetting resins, epoxybased polymers are widely used in the development of advanced composites owing to their superb properties, including but are not limited to high modulus, good creep resistance, distinguished glass transition temperature (T g ), anti-shrinkage, excellent chemical resistance, and lightweight. 4 In addition, some premium resins can maintain their stability even in high-temperature environment up to 176 C. 5,6 At a reasonable temperature, the compatibility of epoxy with the fibers and fillers appeared to be the best among all the polymer composites. 5 As a result, epoxy has been chosen as the ideal matrix resin for the production of polymer composites.…”

“…In overall, graphene as reinforcement in polymer composites enhances the mechanical properties, flame retardancy, toughnes and thermal stability [46][47]. These graphene reinforced polymer composites with enhanced properties can be utilized for manufacturing of components such as blades, bumpers, motor covers, pump housings and aircraft structural parts [48][49].…”
