This study aims to investigate the effect of the content of wood flour on limiting oxygen index (LOI), impact strength, and water absorption and thickness swelling of wood flour / polypropylene composite. For this purpose, the content of wood flour (WF) was 40, 50, and 60 wt. %, with the sieve size of mesh 60, and the maleic anhydride polypropylene (MAPP) content being 2 wt % , respectively. Properties of limiting oxygen index, impact strength, and water absorption and thickness swelling were measured according to relevant ASTM D 2863, ASTM D 256, and ASTM D 7031 standards respectively. The obtained results showed that an increasing the wood flour content to 60 wt. %, the impact strength decreased. The water absorption and thickness swelling of composites was lowered with the decrease in wood flour content. With increasing the wood flour content to 60. wt %, the limiting oxygen index increased.
