The Mechanical Behaviour of Eggshell and Coconut Coir Reinforced Composites

Abstract--In present days, automobile industries are rapidly increased. All the automobile industries are in the process of supplying the vehicles at low cost. The major cost of the automobile components is its body parts. As per the European Union and Asian countries automotive components end life is very important factor in the design of the automotive. So everybody is concentrating on new materials which will be strong enough, less weight, recyclable with reduced cost. Hence all the researchers are concentrated on the composite materials which have all the above properties. Generally the composite materials are synthetic and natural. In that natural fibre is ahead of synthetic with their low cost, low density, stiffness, fairly mechanical properties, high specific strength, non-abrasive, eco-friendly and biodegradable characteristics. In our country much amount of coconut coir fibre is obtainable which have good tensile strength. Similarly large amount of egg shells are also on hand as wastage from food industries which normally produces pollution. But this egg shells are having good compressive strength. Hence the present work is concentrated on coconut coir fibres and egg shell composites. The strength of the composites depends on the compositions of the ingredients. So to obtain new composite materials different proportions of coconut coir and egg shell powder is added and the mechanical properties of all the components are tested and the same is represented. Key words: Coconut coir fiber, eggshell powder, epoxy hardener and resin. I.
