THE MECHANICAL PROPERTIES OF NATURAL CELLULOSIC FIBER/BIODEGRADABLE POLYMER BIOCOMPOSITES
The aim of this work was to investigate a methodology for the improvement of the mechanical properties of sustainable biodegradable biocomposites based on polylactide (PLA).Cellulosic fibre was incorporated as a reinforcing agent for improvement of the mechanical properties of the biocomposites.A coupling agent was synthesized and employed in order to enhance the interfacial adhesion of two components via a melt blending process.FT-IR spectra showed presences of specific functional groups of maleic anhydride on the backbone of the PLA after the grafting.The modulus of PLA was considerably raised after incorporation of the fibre.Furthermore,an addition of a coupling agent in PLA biocomposites was also able to remarkably increase the stiffness of the material.
