This research concerns the using metal powders and MDF production wastes as alternative sources to
natural fibers in manufacturing wood–plastic composites (WPCs). The objective of this work was to
investigate the influence of various levels of MDF dust and aluminum powder (AlP) on physical and
mechanical characteristics of MDF dust/polypropylene composite. Polypropylene was used as a thermoplastic
matrix, and maleic anhydride grafted polypropylene (MAPP) as a coupling agent. Hot pressing
method was used to prepare samples with 1 g/cm3 nominal density. The mechanical and physical properties
were measured according to the technical specifications CEN/TS15534 and ASTM standard D 570,
respectively. It was found that mechanical properties decreased and water absorption and thickness
swelling increased with increasing amount of MDF dusts and AlP. Applying field emission scanning electron
microscopy (FE-SEM), the aluminum powder and composite morphology was studied.
