The main motive of this work is to analyze the electrical properties of chemically treated coir fibre reinforced epoxy composite at room temperature and different frequencies. In the present study coconut coir was collected locally and was used in fine coir dust form as particulate reinforcement in the fabricated composite. The laboratory result reveals that both fibres are effective in increasing the Marshall stability of the ordinary HMA. 1.INTRODUCTION Natural fibers were obtained by nature from plants (stems, leaves, roots, fruits and seeds, etc).Efforts has been taken to use natural fibers as reinforcements in polymer composites from very olden days. Fiber or fibre (from Latin: fibra) is a natural or man-made substance that is significantly longer than it is wide. The addition of coconut fiber to coconut dust increased the airspace (Air at - 10cm tension) but reduced easily available water. The water buffing capacity was lower in coir than in peat. This article will focus on coco as a growing concept and explain some of its physical and chemical properties. The tensile properties of the composite samples were measured for each fibre content value (5, 10 and 15%) with the help of the stress/strain curves. Unlike the weak chemically softened fibre, microbial treatment produced soft, brighter fibres having better tensile strength and elongation properties (Rajan et al., 2005) Biosoftened coir fibre is Perfect for use as a growing medium. Cow dung powder is added as filler to the composite with a purpose of improving the insulation property of the composite.
