ABSTRACT: This study provides an overview on green composites degradability.
Practically, the main drawbacks of using natural fibers are their poor
dimensional stability, degradability and high degree of moisture absorption.
While, end use of product from natural fiber filled or reinforced composites
has become subject of concern to material engineers and scientist. The major
properties of natural fiber reinforced polymer composites are greatly dependent
on the hydrophilic tendency and dimensional stability of the fibers used,
morphology aspect ratio for long fiber, while voids for powder fibers. The
effects of chemical treatments on cellulosic fibers that are used as
reinforcements for thermoplastics were studied. The chemical source for the
treatments is alkalization. The significance of chemically-treated natural fibers
is seen through the improvement of mechanical properties. The untreated fiber
composites degrade faster in municipal soil compared to treated fiber
composites.
