Cellulose, which awards the mechanical properties of the complete natural fiber, is ordered in micro-fibrils enclosed by the other two main components: hemicelluloses and lignin. Bio composites are employed in automotive, building, appliance, packaging and biomaterials. The main advantage of employing natural fibers is that these are biodegradable and renewable and exhibit low cost, low density and high toughness. In this paper, the extraction of cellulose from plant fiber will be carried out by Water pre hydrolysis, chlorination and alkaline extraction. Kenaf plant is used for the extraction of cellulose. The plant belongs to Malvaceae family .the composites were prepared by using cellulose and a bio polymer by using Hand – Layup method. The Composites are characterized by means of Water Absorption test, Flexural test based on ASTM Standards.

INTRODUCTION Recent times have witnessed fierce discussions on the climate changes stressing the need for clean environment and utilization of renewable resources thus minimizing the dependence on dwindling natural resources such as wood and oil. Use of synthetic polymers in every segment of our life has increased the plastic waste in large quantities, which forms one of the major environmental problems the world is facing today. New environmental regulations and societal concern have triggered the search for new products and processes that are compatible to the environment. Strategies/processes to overcome this environmental problem is the use of bio based polymers, bio composites which are derived from renewable materials, leading to the development of 'green or eco-composite materials' that can be easily degraded or bio assimilated. Natural fibers, which traditionally were used as fillers for thermo sets, are now becoming one of the fastest growing performance additives for thermoplastics .Natural/Bio-fiber composites (Bio-Composites)are emerging as a viable alternative in many applications. The general environmental awareness and new rules and regulations will contribute to an increase in the work for more Eco-friendly concept in many applications. These materials are expected to be one of the important materials to realize and recent advances in genetic engineering, natural fiber development and composite science offer significant opportunities for improved value-added materials from renewable resources with enhanced support of global sustainability which maintains a sustainable productive society.
