& Technology, Karnataka, India ---------------------------------------------------------------------***-------------------------------------------------------------------Abstract- Fiber-reinforced polymer composites have played a dominant role for a longtime 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. 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. An attempt has been made to utilize the coir, as natural fiber abundantly available in India. Natural fibers are not only strong and lightweight but also relatively very cheap. The present work describes the difference between development and characterization of a new set of natural fiber based polymer composites consisting of Treated and untreated coir’s as reinforcement, Tea powder as filler, epoxy as resins. Coir composites were developed and their mechanical properties were evaluated at different volume fractions and tests were carried out and the results were presented. Experimental results showed that the composite material of treated coir, Tea powder is the best of all other combinations. 1. INTRODUCTION The composite materials have been used from centuries ago, and it all started with natural fibers. Natural fibers have become important items in the economy and in fact, they have turned out to be a significant source of jobs for developing Countries. Today, these fibers are assessed as environmentally correct materials owing to their biodegradability and renewable characteristics. For example, natural fibers like sisal, jute, coir, oil palm fiber have been proved good reinforcement in thermo set and thermoplastic matrices. Composites are materials that comprise strong load carrying material (known as reinforcement) imbedded in weaker material (known as matrix). Reinforcement provides Strength and rigidity, helping to support structural load. The matrix or binder (organic or inorganic) maintains the position and orientation of the reinforcement. Significantly, constituents of the composites retain their individual, physical and chemical properties, yet together they produce a combination of qualities which individual constituents would be incapable of producing alone reduced weight and increased performance properties have paved a path to development of advanced © 2017, IRJET

engineering materials. Composite products have good mechanical properties-to-weight ratio and the technologies permit the manufacture of complex and large shapes .Fillers are added to a polymer matrix to reduce cost(since most fillers are much less expensive than the matrix resin), increase modulus, reduce mould shrinkage, and produce smoother surface. The major constituents of particulate (filler added) composites are particles of mica, silica, glass spheres, calcium carbonate, or others The application of natural composites is being targeted in various fields due to the environmental and economic benefits which could be used in automotive industry as interior parts and in constructions sector such as walls and roofs. Nowadays, many industrial companies are looking for new composites material, which has good and specific properties like mechanical and chemical characteristic. In searching for such new material, a study has been made where coconut fiber (also known as coir fiber) is compounded with composite material. Coir is the natural fiber of the coconut husk. It is a thick and coarse but durable fiber. It is relatively waterproof and has resistant to damage by salt water and microbial degradation. 2. OBJECTIVES The objective of this project is to prepare and analyze a hybrid composite material, test its properties and compare the results with the normal sample. Preparation of the composite material with tea powder by cold press method. Testing of specimens as per ASTM (American Society for Testing and Materials) standards. 3. MATERIALS USED
