Mechanical properties of wood dust and recycled polymers blends composition in injection moulding

Abstract

Composites based on natural fiber reinforcement and recycled plastics blends has produced wide research and composites engineering interest in previous decades due to their high strength, small density, low cost, light in weight, recyclability and biodegradability as far as green technology is concerned. The tensile strength and water absorption were investigated at the different loading ratio. In this paper, wood dust, recycled Polyethylene Terephthalate, recycled Polyethylene (rPET/rPE) and SEBS-g-MA compatibilizer were processed with different wood dust loadings of 5, 10, and 15 wt %. In addition to molding process parameters such as the melt temperature and injection pressure will be considered which is influenced on part quality. From the observation it was indicates that the mechanical properties of tensile has increased with 15 wt % fiber whereas the water absorption also increased due to the hydrophilic nature of the filler.
