Abstract

In recent years, natural fiber composites have arisen as a possible replacement for the conventional polymer composites; as environmental concerns arise. Natural fibers gain popularity due to their magnificent properties such as percentage elongation, tensile strength bio-compatibility and impact strength. The expansion of natural fiber used in the medical industry is a notable strategy for creating products that are affordable, bio-degradable, and durable. In the present chapter, treated and raw banana fibers are reinforced with poly-lactic acid (PLA) to fabricate fully bio-compatible polymers through the injection moulding process. The banana fibers are treated with a 5% (w/v) alkaline solution for its surface modification. The influence of fiber treatment and its different concentrations (10%, 20%, and 30%) on the mechanical characteristics of bio-composites are investigated. The study concludes that the mechanical properties of banana fiber reinforced bio-polymers are enhanced as fiber concentration increases. However, after alkaline treatment, the bio-polymers exhibited a decrease in impact strength and an increase in tensile strength. Furthermore, the findings indicate that banana fiber reinforced bio-polymers have the potential to be used in a wide range of applications which include bio-medical and furnishing.
