A composite material is made by combining two or more materials to give a unique combination of properties, one of which is made up of stiff, long fibres, and the other, a binder or 'matrix' which holds the fibres in place. The fibres are strong and stiff relative to the matrix and are generally orthotropic. Composites are a versatile and valuable family of materials that can solve problems of different applications, improve productivity, lower cost and facilitate the introduction of new properties in materials.

The fibres are strong and stiff relative to the matrix and are generally orthotropic. Composites are a versatile and valuable family of materials that can solve problems of different applications, improve productivity, lower cost and facilitate the introduction of new properties in materials. Among all the synthetic fibers, glass fibers are now dominant due to their low cost (compared to carbon and aramid) and comparatively better physico-mechanical properties. However, the manufacture, use and removal of traditional composite structures made of glass, carbon and aramid fibers are considered negatively due to growing environmental consciousness. For this reason, alternative reinforcement with natural fiber in composites has recently gained attention due to low cost, low density, acceptable specific properties, ease of separation, enhanced energy recovery, C02 neutrality, biodegradability, and recyclable nature. Though the pioneering work in natural fiber thermoplastic composites started in 1970 lot of development has taken place. Among all the natural fibers, jute appears to be the most useful, inexpensive, and commercially available fiber, which can be moulded into a variety of flat- and complex shaped components by exploiting their attractive reinforcing potential.
