Incorporação de bagaço de gengibre em uma matriz de poliácido lático (PLA)

Abstract

The development of sustainable materials has become a priority in industry and academia, due to the growing concern for environmental conservation. In this context, biodegradable polymer matrix composites emerge as a promising solution, and the use of fillers from renewable sources, such as vegetable fibers, fits the work proposal in relation to this environmental motivation. The objective of this work is the production and evaluation of the mechanical, thermal and morphological properties of polymeric matrix composites of polylactic acid (PLA), using bagasse of ginger as filler in the proportions of 5% and 10%. The composite was obtained through the extrusion process, and the test specimens for characterization were produced by injection molding. Characterization was carried out using SEM, DSC, TGA, and tensile testing. An increase in the composite’s stiffness was observed with higher filler content, along with a reduction in ductility and strength. The composite also showed lower thermal stability compared to PLA.
