In this study, the possibility of producing wood-plastic panels was studied using two different blending methods including melt blend and dry blend. Wood-plastic panels were made from recycled high density polyethylene (as resin) and MDF waste (as natural fiber) at 60, 70 and 80% by weight filler loading. Nominal density and dimensions of the panels were 1g/cm3 and 35×35×1 cm, respectively. The mechanical properties of the panels including flexural elastic modulus, flexural strength, screw and nail withdrawal resistance, and impact strength were studied. Maximum values of flexural modulus of wood-plastic panels were found at 70% fiber content in both methods. Flexural strength, screw and nail withdrawal resistance and impact strength of wood-plastic composites reduced with the increase in fiber content from 60% to 80%. Mechanical properties of samples made with dry blend method were generally higher than those of samples made with melt blend method for all corresponding formulations.
