A good numberof research works havebeen carried out on effect of alkali treatment on the properties of natural fibres and its composites, which motivated for this review. Introduction Natural fibers have made a remarkable impact as a potential substitute for conventional synthetic fibers like But having good mechanical strength up to 3000 MPa. The properties of coir fibres vary and that may give difficulties to some construction due to the flexibility and rupture of the fibres. The density data represents the apparent density, which is the density of the whole fibre, not the fibre cell wall. Kenaf fivers, for example, have excellent specific properties and have potential to be outstanding reinforcing fillers in plastics. For many thousand years, the usage of fibre was limited by natural fibres such as flax, cotton, silk, wool and plant fibres for different applications. the plantation environment. The two-volume Handbook of natural fibres is an indispensable tool in understanding the diverse properties and applications of these important materials. The bamboo has composites have been published as authorsknown. As a general rule, the smaller the diameter of the fiber, the higher its strength, but often the cost increases Chemical properties Chemical analysis of palm fiber shows high cellulose content as seen from Table 1. The prepared polymer composite has the lowest porosity, homogeneous surface structure, and the greatest interface bonding. Natural fibres are used as reinforcement in structural applications in automotive industry. From the physico-mechanical characterization such as: hardness measurement, density measurement, void fraction or porosity measurement, and flexural strength measurement, it is found that the prepared composite is of light weight and high strength. Fibres - The length of fibers may vary from 1 to 2 in. Therefore, natural fibres could potentially be used to replace synthetic fibres in the near future in aerospace applications. Engineers and designers specifying the use of materials in structures will find this book an invaluable guide to best practice throughout the range of industrial sectors where FRCs are employed. 2010).
