Developments in Eco-friendly Composite Materials: Applications of Chemically Treated Natural Fibers in Polymers

Addressing the growing concerns on environmental damage because of plastic waste and the increasing depletion of fossil resources has changed the focus of material science towards greener alternatives. The concern of Natural Fiber Reinforced Polymer Composites is their availability, as they are renewed and biodegradable and easy to compost. Natural fibers are intrinsically low in efficiency for composite usage because of their compatibility to hydrophobic polymer matrices. Nevertheless, the perimeter of natural fibers is enhanced by chemical treatment, improving their mechanical, thermal and environmental properties, which in turn makes them more useful for industrial purposes. This report explores various chemical treatments to natural fibers, the impact of the fibers on the resultant composite, along with their application in the automotive, construction and packaging industries.
