Studies on mechanical and thermal behavior of e glass jute fiber reinforced with poxy isophthalic composite by hand layup vartm method for low cost automobile application

Abstract

CO2 and other toxic emissions from vehicles cause global warming and climate change. This is a serious problem the world is facing right now. One of the best solutions to reduce this effect is to replace the use of existing sheet metal with lightweight composite parts in automobiles. Fiber Reinforced Polymer (FRP) composites can rectify drawbacks of conventional metal such as High Strength Steel (HSS) and aluminum due to their high strength and stiffness-to-weight ratio. Therefore, FRP composite can be widely used in automobiles, aircraft, windmill etc., The main aim of this study is to find a solution will exceed the limitations of the composite such as high cost, low binding nature and high environmental damage. In this study a novel glass fiber/ isophthalic resin composite car bonnet was fabricated using Vacuum Assist Resin Transfer Molding (VARTM), [+45/0/90/-45]6 fiber fixed row (stacking sequence), and 52% of fiber volume fraction (Vf%). newlineIn this work, investigation was conducted for synthetic glass fiber, hazard-free natural jute fiber, highly stable epoxy resin, and low-cost isophthalic polyester resin. In addition, the composite is developed using traditional hand layup and advance VARTM methods. In addition, hybrid glass/jute isophthalic composite was also fabricated. In this work, seven composite materials specimens with different fiber contents, resin, thicknesses, stacking sequences and Vf% values were used to calculate the composite density, Vf%, percentage of void, and resin viscosity. As a result, showed Vf% is achieved (22% 45%) for hand layup and (52%) for VARTM. The result of the mechanical and environmental impact test showed that void plays a significant role in determining the properties of an object. newline
