Evaluation and prediction of the tribological behavior of graphene nanoplatelet‐ and jute microfiller‐based bio‐epoxy hybrid composites

Abstract Recently, the development of cost‐effective, zero‐carbon‐footprint and multifunctional sustainable materials has been a major concern for researchers and scientists. Thus, the present work addresses the development and characterization of hybrid polymer composites integrating jute microfillers and graphene nanoplatelets (GNPs) with epoxy resin matrix. Jute, recognized for its high tensile strength and biodegradability, and GNPs, prized for their superior thermal conductivity and mechanical qualities, with greater surface interfacial, are mixed to improve the tribomechanical and viscoelastic properties of the composites. The composites are produced by varying the GNP weight percentages (0.2–1.0 wt%) with 5% of jute filler reinforcements. The results revealed that the addition of 0.6 wt% GNPs greatly increased the interfacial interaction between fillers and matrix with higher mechanical strength, stiffness and thermal stability and improved viscoelastic properties. Moreover, the addition of 0.2 wt% GNPs in the fabricated composites led to the highest resistance of tribological characteristics (wear and friction) under the influence of increasing load and sliding distances. Additionally, machine learning techniques have been employed to forecast the wear and frictional behavior of the hybrid composites. The support vector machine (SVM) method stood out from the others due to its higher performance. Through the balance of robustness and environmental sustainability, this research validates the prospective of jute–GNP–epoxy hybrid composites for sophisticated engineering applications. © 2025 Society of Chemical Industry.
