Experimental Analysis and Predictive Modeling of Mechanical Behavior in Epoxy Composites Reinforced with Waste Tyre Rubber ParticlesBy Sivakumar Sambath, Rajasekar Rajendran, Sabarish Rajagopalan
Abstract: The disposal of end-of-life tyres poses a significant environmental and resource challenge owing to their large volumes and non-biodegradable nature. In this work, we explore the incorporation of waste tyre rubber particles (WTRP) into an epoxy resin matrix to develop sustainable polymer composites and examine their mechanical behavior both experimentally and through predictive modelling. Composites with differing epoxy: WTRP ratios (80:20, 75:25, 70:30 wt.%) and varying rubber particle mesh sizes …

Mechanical Characterization of Prosopis Juliflora Fibre-Reinforced Epoxy Composites for Sustainable Automotive ApplicationsBy Sivakumar Sambath, Rajasekar Rajendran, Sabarish Rajagopalan
Abstract: This study investigates the potential of Prosopis juliflora (PJ) fibre as an eco-friendly, economical, and mechanically efficient reinforcement for epoxy-based polymer composites. Composite samples were produced using the compression moulding technique with epoxy-to-fibre weight ratios of 90:10, 85:15, and 80:20. Mechanical tests, including tensile, flexural, impact, and hardness evaluations, were conducted in accordance with relevant ASTM standards. The incorporation of PJ fibre resulted in significant improvements in the mechanical behaviour …
