Hybrid Hemp Fiber-Reinforced Epoxy Composites with Graphene\'s Water Absorption Over Time and Impact on Mechanical Properties

Abstract

Abstract: For many technical applications, there is rising interest in using natural fibres instead of artificial ones for making polymer composites. It should be demonstrated that it is suitable for use in outside situations given their purported hydrophilic inclination. The behaviour of hybrid hemp fiber-reinforced epoxy composites containing 0%, 0.5%, 1%, and 1.5% by weight of graphene under immersion in water for 1000, 2000, and 3000 hours was examined in this work. The wood's shear strength was then measured both before and after it was submerged in water. The outcomes demonstrated that the composites' mechanical characteristics were enhanced by the graphene nanoparticles. The Fickian rule was followed in the hybrid natural fibre composites' moisture absorption process, although moisture absorption and moisture were dramatically decreased by the use of graphene. After 3000 hours of exposure, the hempural strength of hybrid composites containing 0%, 0.5%, 1%, and 1.5% was assessed.
