India, endowed with an abundant availability of natural fibres which can be termed as green fibres such as jute, coir, sisal, pineapple, ramie, bamboo, banana etc., has focused on the development of green composites primarily to explore value-added application avenues. Such natural fibre composites are well suited as wood substitutes in the housing & construction sector. The development of natural fibre composites in India is based on a two-pronged strategy of preventing depletion of forest resources as well as ensuring good economic returns for the cultivation of natural fibres.
Jute & coir based composites have been developed as substitutes for plywood & medium density fibre boards. Panel & flush doors have also been developed out of these composite boards especially for low-cost housing needs. Other product development activities include usage of sisal fibre based composites as panel & roofing sheets. Incorporation of glass with jute brings about large increases in mechanical properties of composites. The green composites can be very cost-effective material especially for building & construction industry (panels, false ceilings, partition boards etc.), packaging, automobile & railway coach interiors and storage devices.
Use of composites made from natural fibres like jute, sun hemp, coir, flax, bamboo etc. is becoming popular day by day. To prevent de-forestation there is a wide scope and strong need to replace timber product such as plywood, blockboard, particle boards, medium density fibre boards etc. with some cheap, abundantly available and relatively easy to process material. As jute is also lignocellulosic in nature like wood, jute composites are used as substitute for these products.
Jute composites can replace conventional glass fibre reinforced thermoses which are normally used in our day to day life. Various properties of natural fibres composite like water absorption, tensile strength, and flexural strength are compared and discussed. Fields of application of composite made from natural fibres are highlighted.
This paper also deals with various composites made by using flax, coir and bamboo fibres. The potential of such composites are discussed in this paper.
