Abstract : Reinforced polymer composites have played an
Here chemically treated and untreated fibres were mixed separately with polyester matrix and by using hand lay –up technique these reinforced composite material is moulded into dumbbell shape. Five specimens were prepared in different arrangement of natural fibres and glass fiber in order to get more accurate results.
ascendant role in a variety of applications for their high meticulous strength and modulus. The fiber may be synthetic or natural used to serves as reinforcement in reinforced composites. Glass and other synthetic fiber reinforced composites consists high meticulous strength but their fields of applications are restrained because of their high cost of production. Natural fibres are not only strong & light weight but mostly cheap and abundantly available material especially in central uttar Pradesh region and north middle east region. Now a days most of the automotive parts are made with different materials which cannot be recycled. Recently European Union (E.U) and Asian countries have released stringent non concerning Automotive end-life requirements i.e; the parts of the automotives should be recycled.It has been consider as a alternative of conventional material. This increased the use of natural fibers in composite materials. Natural fibers have recently become more attractive to researchers, engineers and scientists as an alternative reinforcement for fiber reinforced polymer composites. Due to their low cost, low density stiffness, fairly good mechanical properties, high specific strength, nonabrasive, eco- friendly and biodegradable characteristics, they are exploited as a replacement for the conventional fiber, such as glass fiber and carbon. There is a wide scope for future scholars to explore the current research area. The present work can be further extended to study other aspects of composites like use of other natural fibers and evaluation of their dynamic mechanical, thermal, tribological properties and the experimental results can be similarly be analyzed.
In the present era of environmental consciousness, more and more material are emerging worldwide, Efficient utilization of plant species and utilizing the smaller particles and fibers obtained from various lignocellulosic materials including agro wastes to develop eco-friendly materials is thus certainly a rational and sustainable approach. Any lignocellulosic waste matter can, therefore, be turned into composite products through appropriate R & D work and development in technological aspects. These approaches offer much simpler materials for future use in comparison to metal based composites. Resilience property which makes plastics ideal for many applications like food industries, packaging, construction field and sanitation products etc. petroleum-derived plastics can lead to waste disposal problems, as these materials are not readily biodegradable and because of their resistance to microbial degradation, they accumulate in the environment.
2. FIBER Nowadays natural fibers form an interesting alternative for the most widely applied fiber in the composite technology, the use of fibers like flax, hemp, jute or sisal is small since availability of a durable semi-finished product with constant quality is often a problem. Recent research and development have shown that these aspects can be improved considerably.

1. INTRODUCTION
2.1 Natural fiber: 2.1.1.Cotton 2.1.2.Jute
Environmental awareness is growing day by day. Worldwide researchers triggered by this reason to implement and utilize materials which are eco friendly. When compared to synthetic fibres and manmade fibres natural fibres become best alternative and it is cheaper and more economic and environmental friendly composite material. In this experiment coconut coir fibre is the natural fibre component chemically treated with alkaline solution.
