Evaluation of fiber volume fraction of kenaf-coir-epoxy based green composite by finite element analysis

Abstract

Scientists and specialists have moved their attention from conventional synthetic composites to green fiber composites. These fiber strands are light in weight as well as high in strength and more reasonable and economical in comparison to the regular fibers. Additionally, the green fibers are biodegradable, sustainable, and environmentally friendly. Among various other natural fibers, the kenaf fibers show higher and better properties as composite reinforcement compared to other fibres, in presence of varying loading conditions. Whereas coir fibers have been found to possess excellent strength and durability. Epoxy resin possesses magnificent binding characteristics and is treated as a good matrix for the development of composites. In previous researches, it has been seen that fiber stacking or fiber part volume, influences the mechanical strength, qualities, and properties of green fiber- composite. Therefore, this study has been focused on evaluating the fiber volume fraction and strength of kenaf coir fiber-based epoxy composite material by analytical as well as finite element analysis techniques. This paper likewise proposes an analytical model based on the rule of hybrid mixtures, and solutions of flexural and tensile tests conducted on ANSYS 15.0. Based on this research, it can be stated that kenaf-coir composite may be utilized for a varying loading modern application.
