Utilization of Waste Marble Dust in Poly(Lactic Acid)-Based Biocomposites: Mechanical, Thermal and Wear Properties

Abstract The aim of this present work was to study the applicability waste marble dust (MD) in poly(lactic acid) (PLA)-based composites. Samples containing up 20 wt% MD were prepared via melt blending. attention focused on investigation mechanical, morphological, thermal properties and wear resistance PLA/MD Regarding mechanical properties, both tensile flexural modulus improved remarkably, however, a slight loss observed strength deformability. impact toughness showed an increasing tendency 10 loading, which followed by marginal decrease at higher concentration. With respect sliding rate, composite with highest content best resistance. According DSC measurements, hampered chain mobility PLA, thereby reducing crystalline ratio. Overall, composites developed, while reuse is expected reduce production costs as well.
