Work has been carried out to investigate the flexural properties of composites made by reinforcing bagasse, coir and banana fiber of different ratio as the new natural fibers into epoxy resin matrix. The hybridization of the reinforcement in the composite shows almost same strength when compared to particle board used in our industry but the price is much lower than our natural fibers reinforced composites. Composite which contains 70% Bagasse and 30% coir has almost same strength, higher density, lower water absorption rate and lower price which are economically and environmentally very friendly. Keywords: Bagasse, Coir, Binder, Epoxy. I. INTRODUCTION A multidisciplinary team is being assembled focused on improving the growth, harvesting, treatments, and development of new agri-based precursors for processing structural bio based composites in local and territorial composite manufacturing facilities for use in a vast range of applications. Natural fibers, as reinforcement, have recently drawn the attention of researchers because of their values over other established materials. They are fully biodegradable, environmentally friendly, abundantly available, Corrosion resistance and renewable. Plant fibers are light compared to glass, carbon and aramid fibers. The biodegradability of natural fiber can contribute to a healthy ecosystem while their low cost and high performance achieves the economic interest of industry. S.M. Sapuan and J. Sahari of University of Putra Malaysia had done research on bio-composite material consists of natural fiber reinforced polymer biodegradable composites in 2011.[1] D. Chandramohan and J. Bharanichandar worked on mechanical test on natural fiber reinforced polymer composite materials in 2013.[2] Cao Y11 et al investigated reinforced biodegradable composites with bagasse fiber before and after treatments of Alkali were prepared and mechanical properties were investigated. [3] Mechanical properties had been analyzed of jute fiber reinforced thermoplastic composites.[4] A method was investigated to fabricate short bagasse bamboo fiber reinforced biodegradable composites and investigated their flexural properties.[5] N.Venkateshwaran studied the flexural, tensile and water absorption studies of banana-epoxy composite materials which showed a deficient result and it can be upgraded in a better way by the addition of sisal fiber along with banana fiber in different weight percentages.[6] In 2014, A.Rukaya, T.K.Shagupta of Rajshahi University of Engineering And Technology has done project on research and development of biocomposit material consisting of wood staw recycle plastic. [7] In J. Madhukiran, Dr. S. Srinivasa, of M.V.G.R Collage of Engineeringn has done research on Fabrication & Testing of Natural Fiber Reinforced hybrite Composite Banana, Pineapple. [8] Fabricating an efficient and light weight of natural fiber composite material with high strength from sustainable resources, such as Coir, Bagasse and Banana Fiber, is quite attractive from both application and environmental point of view. This paper demonstrates the fabrication of natural fiber composite material with varying composition of different fiber, characterizes their physical and mechanical properties and compares these properties with that of wood base particle board. The raw material is commonly available in agricultural sector. II. MATERIALS The raw materials for the composites are Bagasse, Coir, Banana fiber and epoxy resin. So at first raw materials were collected. A. Bagasse: Bagasse fiber was obtained from sugar cane. At first the obtained fibers were cleaned, then dried (atmosphere + oven) to remove the moisture. After that the fibers were crushed to reduce the size B. Coir: Coconut fiber is obtained from the husk of the fruit of the coconut palm. The obtained fiber were cleaned and dried (atmosphere + oven) to remove the moisture. After that the fiber was crushed to reduce the size. C. Banana Fiber: Banana fiber is extracted from the bark Banana plant. The obtained fibers are cleaned with water and dried (atmosphere + oven) to remove the moisture. After that the fibers were crushed to reduce the size. Table 1 shows the composition of Bagasse, Coir and Banana Fiber.
