The results showed that the influence of the percentage of the needle-shaped fiber on the impact strength of NF-WPC was significant, while much more significant on the bending and tensile properties. The percentage of MAPE influenced significantly to the tensile strength and toughness of NF-WPC. In the conditions of this paper the dimension of wood fiber and the percentage of lubricant paraffin had a minor influence on the mechanical properties of NF-WPC.
