Finite element modelling and analysis of jute fibre reinforced PLA matrix composite

Abstract

A number of environmental issues, including the production of waste, buildup in disposal systems, and recyclability, are major factors in the usage of numerous biodegradable materials. Every day, more and more plastic consumers are requesting and using biopolymers, which is driving up their use. One of the most promising biopolymers that has been thoroughly studied is polylactic acid (PLA), which is now starting to replace plastic materials in several applications. In the same way, natural fibers are beginning to replace synthetic fibers in reinforced composites for a wide range of products due to their technological advantages, economic advantages, and environmental benefits. This research paper delves into the comprehensive exploration of jute fibre reinforced PLA matrix bio-composite, focusing on their load carrying capacity and strength. Through empirical analysis, the research showcases the specific case of Jute Fibre-PLA composite, which serves as a representative example to highlight the exceptional compatibility and potential advantages of bio-composites over traditional synthetic alternatives. In this work, PLA matrix and Jute fibres have been used to prepare the composite material. By using Finite element method (FEM), Jute fibre lengths of 140 mm (long fibres) and 9 mm length (short fibres) were analyzed. Results revealed that short fibres have the effective strengthening property as compared to long fibre lengths.
