Natural fibre composites plant-based fibres

Natural fibres can be obtained from various parts of a plant, as shown in Table 13.2. Natural fibres can be continuous fibres, short fibres, whiskers or particles, as shown in Figure 13.4. Types of polymer composite based on shape and structure are divided into particle, fibre and structural. 

Back to Namre is the present day mantra of the modem world. The current trend is to find out new materials based on natural substances. Increased environmental awareness and the current economic simations tempt the modem man to make use of Natural fibres in developing new composite materials. Namral fibres are extracted from various parts of plants, and several extraction procedures are in vogue. The fibre properties depend on the part of the plant from which the fibres are obtained and the extraction methods used.

Plant oils and animal fat are mostly unsatured fatty acids. Some of these oily products are already well known by the public from their use in paint (e.g., flax (linseed) tung oils are drying oils used in paints, varnishes and enamels) or in soaps, detergents, cosmetics and lubricant applications. Plant oils increasingly become a source of raw material to produce thermoset resins that can be mixed widi natural fibres in order to achieve light and resistant composite materials. The combination of bio-based resins with natural fibres (plant and poultry) or...
