The main objective of our work is to perform and to analyze the mechanical behaviors of kenaf and glass fibre using various mechanical tests such as strength, hardness and many other properties which helps to apply in various industrial and mechanical oriented applications. In this research, Kenaf is separated as treated and untreated composite materials. The kenaf is dipped with the mixture of ethanol and silicon di oxide which is known as treated process and the non-dipped kenaf is known as untreated process. The plates are arranged in the form of 2 kenaf layers and the glass fibre is inserted in the middle, it is molded with the help of epoxy resin. Then each plate are separated with silicon of 0%,1% and 2.5%. Then various tests such as flexural, tensile, impact are being performed and noted as treated and untreated values. The resulting values are plotted in the form of graph which will be easy for the comparison of treated and untreated materials. By finding these ratios, it helps in the replacement with other material properties. So we conclude that our aim is to test and compare both treated and untreated plates to find their properties and applications.
