Waste wood particles of different shapes were used to reinforce high density polyethylene (HDPE) to prepare high performance wood/plastic composites (WPC). The wood particles showed a needle-, flake-, strand-, and powder-shape, respectively. The mechanical and water-uptake properties of the composites manufactured using extrusion were tested. The wood needles/HDPE composites (WN-WPC) exhibited slightly higher mechanical strengths and lower density than the composites with the other shapes of wood particles. When the flake-, strand-, and powder-shaped wood particles were replaced by wood needles, the flexural, tensile and impact strengths were increased approximately by 4.24%, 7.61%, and 16.6% on average, respectively, and the density was decreased by about 7.34%. The length and width of WPC specimens changed little when soaked in water, with the thickening on the edge area only. WN-WPC performed the best waterproof stability. Based on the experimental results, the wood needles with lager length-to-diameter ratio would be the most suitable for producing high performance WPC.

Enormous amounts of plastic wastes are generated worldwide and the approaches related to plastic recycling or reusing have become the research focus in the field of composite materials. In this study, green composites were prepared via melt-blending method using high-density polyethylene (HDPE) sourced from plastic bags as a matrix and sugarcane bagasse (SCB) fiber as reinforcing filler. The effects of fiber loading (5, 10 and 15 wt%) and fiber modification on the mechanical and dimensional stability (weight gain by water absorption) properties of the green composites were investigated. Results showed that the inclusion of SCB fiber into recycled HDPE matrix increased the composite stiffness but decreased the mechanical strength and resistance to water absorption. With the fiber modification through alkali treatment, the mechanical strength was remarkably improved, and the modulus and water absorption of the composites were found to be reduced. From the finding, it can be concluded that the prepared green composites free of coupling agent could add value to the plastic and agricultural wastes, and serve a potential candidate to replace some conventional petroleum-based composites.
