Abstract

The advantages of green composites are including, but not limited to their environmental friendly nature, lightweight, reduction of production energy and costs, and recyclability. This work focuses on the mechanical, thermal, and dynamic mechanical properties of biocomposites. For that purpose, biosourced polymers were used, namely polylactic acid (PLA) and sisal fiber, and biocomposites were extruded and then injection molded with different contents of sisal fibers (5%, 10%, 15%). The results show that the increase of the rate of reinforcement improves the mechanical and dynamic mechanical properties of the biocomposites made. By the increase of the sisal fiber content, the degree of crystallinity of the matrix was increased from 47% to 61%, as sisal fibers were acted as a nucleating agent for the PLA.
