Abstract
The use of natural fibers in making a variety of synthetic material has attracted attentions due to mainly two causes. 1. Making use of waste material into usable composites and 2. To tide over disposal of waste which otherwise causes degradation of environment. In the present study raw coir fiber was chemically treated with nitro compounds. It is a kind of chemical modification of fiber. Treated fiber was reinforced with epoxy polymer in the 1:1:1(resin: hardener: treated fiber). Dielectric estimation of the resulting composite was done with Wayne Kerr impedance analyzer in the temperature range of 30Oto 180OC at different frequencies. Systematic variation in properties was found from pure epoxy composite to fiber reinforced epoxy composite. XRD study reveals that composite is crystalline in nature. Change in morphology of the fiber was found when compared with untreated fiber, which is confirmed by Scanning Electron Microscopy. The objective of this study is to utilize the coir fiber, a waste product found in abundance in nature. If natural fibres could be used as reinforcement material in polymers, it may lead to new dimensions to research in the area of embedded materials. It might prove as an asset in electronic, automobile and engineering fields. It is lightweight; bio-degradability makes it a potential in new arena when India goes green.Keywords: coir, fiber, reinforcement, polymer
