Influence of natural fibers on the mechanical properties and biodegradation of poly(lactic acid) and poly(e-caprolactone) composites: a review

Abstract

This article highlights developments in viable poly(lactic acid) (PLA) and poly(e-caprolactone) (PCL) ecofriendly products with enhanced mechanical properties and biodegradation based on natural resources for both reinforcements and matrices. In recent times, several techniques have emerged with emphasis on enhancing mechanical, biological, and chemical properties equivalent to or superior to conventional polymers in use. Chemical and physical modifications of the fibers and in some cases polymer matrix or both are used to obtain properties suitable for the intended application. The mechanical properties and biodegradation of PLA and PCL natural fiber composites were enhanced by the treated fibers.
