Utilisation of MDF waste for wood plastic composites production

44096

The aim of this study was to evaluate the potential utilization of fibre board waste generated from forest industry and furniture manufacturers in the production of wood plastic composite (WPC) for replacing wood flour. For production of WPC, polypropylene (PP) was chosen as polymer matrix, and eight different compositions were prepared with the co-rotating twin-screw extruder to compound them into pellets. WPC were produced at the size of 25 cm x 25 cm and 2 mm from these pellets (MDF flour loading varies 10 to 50 weight %) by hot press with the compression moulded technique according to ASTM D4703-10. For each composition, three composites were produced and ten specimens were prepared from these composites for tensile, flexural and notched impact specimens The tensile, flexural and impact properties of the manufactured samples were determined in accordance with ASTM D638, ASTM D6109, and ASTM D256, respectively. Morphological properties of the samples were characterized with scanning electron microscopy (SEM) analysis. Tensile and impact strength values decreased with increasing MDF flour loading whereas MOE values were improved with addition of MDF flour. All produced MDF flour filled composites showed better MOE and bending strength properties than ASTM D6662-13 standard requirements for polyolefin-based plastic lumber.
