摘要

Natural fiber-reinforced composites have attracted great research and economic interests because of their outstanding ‘green’ characteristics compared with glass fiber-reinforced composites [1]. But the superior resistance of glass fibers to environmental attack made glass-fiber-reinforced polymers more attractive for marine products and in the chemical and food industries [2-5]. On the other hand, the manufacture, use and removal of traditional composite structures usually made of glass, carbon and aramid fibers are considered critically because of growing environmental conscious [6,7]. Scientists have been faced with the difficult challenge of lowering the human impact on their surroundings while maintaining or even bettering the quality of life. The potential environmental and economic benefits of using natural renewable resource based materials have therefore, led to increased interest in the development of novel bio-composite materials. As a result, lingo cellulose fibers which are a natural fiber have been identified as a potential substitute for commonly applied man made synthetic fibers in the preparation of composites due to their lightweight, low cost, no hazardousness,?biodegradability, renewability and above all environmental friendly characteristics [8-14]. However, some of the infirmities of natural fiber such as wet ability, noncompatibility with some polymeric matrices, low thermal stability, and?hydrophilic?nature of fiber surface, poor adhesion with the matrices and swelling and maceration of the fibers due to moisture absorption have prevented complete replacement of synthetic fibers. But the scientific and industrial path of Fiber Reinforced Polymer (FRP) composites was successful primarily because these materials was able to offer structural efficiency and strength to weight ratios over traditional materials such as metals, plastics and wood. Cellulose fibers from kenaf, hemp, ramie, flax, sisal, coir and jute are also being used as reinforcement and they have some advantages over synthetic fibers such as low abrasion, multi functionality, low density, low cost, unlimited availability and no waste disposal problems which encourage their applications in composite. One of the vastly available natural fibers is jute which is frequently used as reinforcing agent because it is non-abrasive, has low density and high strength. Jute appears to be a promising material because it is relatively inexpensive and commercially available in the required form. It has higher strength and modulus than plastic and is a good substitute for conventional fibers in many situations. Jute composite can be used as particleboard, ceiling, blocks for building construction and furniture.
