Abstract

Increasing demand for special materials lead to new inventions, one of the most promising inventions is the concept of composites. We always will strive to understand and modify the world around us and the stuff of which it is made. A new era is opened when the thorough understanding of a particular material and combining the valuable properties of the different materials are taken together to optimize the individual properties. Nowadays, engineering material at the atomic and molecular levels are creating a revolution in the fields of materials and processing. Nanoscale particles are presently considered to be high potential filler material for improving the properties of the existing material. Due to the nano technology the polymer composites are become more attractive. As surely as polymer composites changed the face of industry twenty-five years ago, polymer nanocomposites will Busher in a new era in materials development. Natural materials are one of the prominent and cost effective options for alternating the synthetic fibers reinforced composites. The availability of the natural material and ease of
manufacturing attracts the researchers to try the locally available inexpensive fibers and to study their feasibility in reinforcing in to polymers. Accordingly extensive studies on preparation and properties of polymer matrix composite (PMC) replacing the synthetic fiber with natural fiber like Jute, Sisal, Pineapple, Bamboo and Kenaf were carried out. These plant fibers have many advantages over glass fiber or carbon fiber like renewable, environmental friendly, low cost,
lightweight, high specific mechanical performance.
There are many potential natural resources, which India has in abundance. Most of it comes from the forest and agriculture. Jute is an annual plant in the genus corchorus. The major types grown are generally known as white jute and tossa jute. Jute, grown mainly in India and Bangladesh, is harvested at 2 to 3 months of growth, at which time it is 3-5 meters tall. Jute is most common agro-fibers having high tensile modulus and low elongation at break. If the low density of this fiber is taken in to consideration, then its specific stiffness and strength are comparable to the respective quantities of glass fibers. Jute contains about 61-71% cellulose, 13-20% hemicellulose, and 12-13% lignin.
