Acacia Wood and Its Surface Treatment for High Strength Bio-composites

Abstract

Till date, the core issue amongst many ecological problems that we face has been about nature and its various pollutions. Wood and natural fiber were known to be the very first materials used to combat noise pollution due to its miraculous properties of high strength and high sound absorption. It was employed as the initial material to reduce the high levels of noise in the harsh environment. Gradually, wood, natural fiber and its waste have become abundant. Moving on, agricultural lignocellulosic materials are also seen as environmentally friendly, reproducible and sustainable fibers. To counter this problem, researchers headed towards the use of synthetic materials that could reduce this problem. It is known that natural fiber and wood composite materials are analyzed to be weak in mechanical properties when compared to synthetic polymer composites, but the sustainability factor insisted the researchers to serve the cause of improving the mechanical properties of natural fiber composite materials. Various methods have now been established to improve and analyze the surface characteristics of wood and natural fibers and hence the mechanical properties of natural fiber composite materials. In this study, a thorough literature review is conducted on the chemical and physical treatment of wood and lignocellulosic residues and their characterization.
