epoxy composite

Abstract

The main factors that influence the properties of composite are fiber length and content.Hence the prediction of optimum fiber length and content becomes important,so that composite can be prepared with best mechanical prop-erties.Experiments are carried out as per ASTM standards to find the mechanical properties namely,tensile strength and modulus,flexural strength and modulus,and impact strength.In addition to mechanical properties,water absorption capacity of the composite is also studied.Further,fractured surface of the specimen are subjected to morphological study using scanning electron microscope.The investigation revealed the suitability of banana fiber as an effective reinforce-ment in epoxy matrix.

Introduction

Nowadays,polymers are used everywhere in the day-to-day life.Plastics found its way when the need for low weight high strength material became important for various applications.The research in thefield of poly-mer and polymer-based components has gained wide-spread recognition owing to its property;however,its bio-degradability is still a matter of concern.Further, glassfiber reinforced polymers(GFRP)have become appealing substitutes for aluminum,concrete,and steel due to its high strength-to-weight ratio,ease of handling,and for being corrosion-free.Moreover, they can also be engineered to get the desired proper-ties.1Since large-scale production and fabrication of glassfiber causes environmental problems and also health hazards,a suitable alternate which is environ-mental friendly is the need of the hour.Naturalfibers that are low cost,lightweight and environmental friendly provide an excellent alternative to glassfiber. Joshi et al.2reviewed the life cycle assessment of natural fiber and glassfiber composite and found that natural fibers are environmentally superior to glassfiber,and also reduces the polymer content as reinforcement. Schmidt and Beyer,Wotzel et al.,and Corbiere et al.carried out some important works using the natural fibers as reinforcement in polymer matrix for use in automobile parts.Schmit and Beyer3have replaced the glassfiber polypropylene(PP)with hemp-PP com-posite for auto-insulation application.Wotzel et al.4 have used hemp-epoxy to replace glassfiber acryloni-trile butadien–styrene(ABS)for usage in auto-side panel.Similarly,Corbiere et al.5replaced glassfiber PP with Curaua PP for transporting pallet.All these studies revealed that the naturalfiber based polymer composite has successfully replaced the glassfiber. Pothan et al.6studied the effect offiber length and con-tent on the mechanical properties of the short banana/ polyester composite.Study shows that30–40mmfiber length and40%fiber loading provides better mechan-ical properties.Idicula et al.7investigated the mechan-ical performance of banana/sisal hybrid composite and Department of Mechanical Engineering,Anna University,Chennai,India.
