Abstract: The aim of this study was to produce and characterize composites made from wood flour and Ultra High Molecular Weight Polyethylene (UHMWPE). Firstly, the composites were initially prepared with wood sawdust provided from a sawmill and this study highlights particularly the use of raw materials in a powder form. Composites were prepared by a simple dry mixing technique and then compression molded. The wood content was up to 30%wt. The effect of wood content on morphology, density, hardness, and mechanical properties (tensile, torsion and flexion) was investigated. The results show that wood flour addition increased substantially all the moduli (up to 97%). The results show also that good dispersion and adhesion were achieved and wood flour addition increased significantly the mechanical properties of the composites.
