Fabrication and study on carbon fiber with epoxy and vinyl ester resins

Abstract

Carbon fibers are fibers of 5 to 10 micrometres in diameter and made of carbon atoms. It is used in various fields like in aerospace, automobile etc because to its high tensile strength, high stiffness and less weight. But it becomes brittle in nature when mixed along with polymer resin, to overcome this carbon fiber is added with resin that gives the composite some ductility. Adding Epoxy and Vinyl ester resins reduces the brittle nature and high resistance towards loaded vibrations will be obtained. This is done by fabricating carbon fiber with epoxy and vinyl ester resins in different compositions by Hand Lapping technique. Different tests were conducted for checking its properties and to know the optimum composition of resins to enhance its properties.
