Keywords: Natural fibers, Mechanical properties, SEM. A wide range of textures can be obtained from different natural fibers (either individually or through a combination of two or more natural fibres). 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. Abstract Epoxy matrix composites reinforced with woven natural fiber were studied. provides the stiffness and load bearing qualities, whereas the low-modulus fiber makes the composite more damage tolerant and keeps the material cost low. The two-volume Handbook of natural fibres is an indispensible tool in understanding the diverse properties and applications of these important materials. conclusion was that chemical treatment of natural bers results in a remarkable improvement of the NFPCs. For many thousand years, the usage of fiber was limited by natural fibres such as flax, cotton, silk, wool and plant fibres for different applications. In general, natural fibres have higher porosity than synthetic fibres. Natural fibers such as jute, sisal, silk and coir are inexpensive, abundant and renewable, lightweight, with low density, high toughness, and biodegradable. In 1896, for example, airplane seats and fuel-tanks were made of natural fibers with a small content of polymeric binders. Natural fibres have recently attracted the attention to be used as reinforcement in plastics. (0.10 to 0.75 mm). Methods of mixing- The two methods of mixing and placing are:- 1.Wet mix 2. Natural fibres find application in various fields like construction, automobile industry and also in soil conservation. The natural fibers are vegetable, animal, or mineral in origin. In the wet mix, a low volume fraction of fibres is used. The natural and manmade fibres differ greatly in respect of porosity which in turn affects other properties of fibres and consequently the processing of fibres during textile manufacture. It may seem surprising, but first natural fiber composites were used more than 100 years ago.
