Natural fibers are bestowed with virtues such as recyclable, biodegradable, posses' low density, appropriate stiffness, disposability, renewability, and other mechanical properties.
A lot of research is undertaken for the application of natural fibers in reinforcements. Due to the threat of global warming, there is an increasing awareness of ecological way of living, which urges the need for providing a great deal of attention towards the improvement of these fibers.
We are living in the era of moving back from petrochemical based fibers to natural fibers due to environmental costs involved in using petrochemical fibers and the non-renewable resources of the synthetic fibers.
Petrochemical products pose health threats due to direct exposure, and secondary exposure through soil, air and water pollution.
Natural fibers can be combined with both synthetic and natural materials like biocomposites for several applications. Many natural fibers such as hemp, palm, bamboo, banana, and ramie are used as reinforcements in place of glass fibers.
