A Research Paper On Experimental Investigations of Mechanical Properties of Composite Material used for Manufacturing Industry Application

In this research composite material is manufactured by using hand layup method and mechanical properties are investigated. By using natural fibers with the epoxy and graphite fibers, the mechanical properties of the composite material show better results. The advantage of composite materials over conventional materials are largely from their higher specific strength, stiffness and fatigue characteristics, which enables structural design to be more versatile. By definition, composite materials consist of two or more constituents with physically separable phases. Tensile strength and bending strength after testing found is very high as compared other composite material with natural fibers. At the end it is found that, this graphite/epoxy/coconut coir composite material is feasible for the mechanical application. Also it is found that tensile and bending strength is high. Fiber-reinforced polymer composites have played a dominant role for a long time in a variety of applications for their high specific strength and modulus. The fiber which serves as a reinforcement in reinforced plastics may be synthetic or natural. Past studies show that only synthetic fibers such as glass, carbon etc., have been used in fiber-reinforced plastics. Although glass and other synthetic fiber-reinforced plastics possess high specific strength, their fields of application are very limited because of their inherent higher cost of production. In this connection, an investigation has been carried out to make use of coconut coir, a natural fiber abundantly available in India. Natural fibers are not only strong and lightweight but also relatively very cheap.
