Biocomposites based on a polymer with good biodegradability, poly(butylene succinate) (PBS), and reinforced
with different lignocellulosic fibers (coconut, sugarcane bagasse, curaua, sisal) were prepared
through the traditional thermo-pressed molding technique. The fibers were characterized in terms of
chemical composition, thermal stability (TGA), cristallinity (XRD) and surface morphology (SEM). The
polymer thermal properties were evaluated by TGA and DSC. The composite characteristics were investigated
by mechanical tests (Izod impact strength, flexural resistance), thermal stability (TGA), water
uptake and SEM micrographs of the fractured surfaces. The results showed that sisal and curaua fibers
feature a huge potential as reinforcing agents of PBS due to their superior chemical compatibility with
the aliphatic matrix as well as to their surface morphology. Both factors contributed to the formation
of a strong interface capable to effectively transfer the load from the matrix to the fibers. Sisal/PBS
and curaua/PBS composites also showed greater resistance against water absorption if compared to
coconut/PBS and sugarcane bagasse/PBS composites. Novel biocomposites with good properties were
produced from fibers and polymer that can obtained from renewable raw materials.
