More recently, the use of natural fibers as a reinforcement in polymer composites has been gaining a lot of attention, especially in the research community, and there are numerous review articles published on the applications of NFCs. However, to date the commercial use of NFCs is limited to wood plastic composites and automotive inner door panels. They are renewable, cheap, completely or partially recyclable and biodegradable. The reinforcing material and the matrix material can be metal, ceramic, or polymer. They are environmentally-friendly, fully biodegradable, Natural fibre composites (NFCs) are composite materials, in which at least the reinforcing fibres are derived from renewable and carbon dioxide neutral resources such as wood or plants. Wood is an example of a natural composite material: it features cellulose fibers that are embedded in a lignin matrix. reinforced with natural fibres to improve the composites properties K r L and these composites provide positive environmental advantages, good mechanical properties and light weight [26-28]. 2Department of Mechanical Engineering, The National Institute of Engineering, Mysore - 570 008, Karnataka, India.
