The aim of this research is investigation on influence of single wall carbon nanotubes (SWCNTs) on the physical and mechanical properties of wood fiber- LDPE composites. SWCNTs with 1, 2 and 3 wt% were dispersed in acetone and then in absent and present MAPE ( 0 and 3% wt) were mixed with wood fiber and HDPE by Haake internal mixer and then the wood plastic composites were manufactured by hot press method. The results show that SWCNTs and MAPE improve physical and mechanical properties of the composites. In absent and present MAPE, the composites with 3% SWCNTs exhibited the lowest water absorption and thickness swelling content and the highest flexural modulus and strength, respectively. SEM micrograph showed that, with adding compatibilizer dispersion of fibers and carbon nanotube are improved. The composites with 3% MAPE and 2% SWCNTs exhibited the highest impact strength. Based on SEM micrograph, with increasing carbon nanoyube up to 3%, these nanoparticles are agglomerated in the matrix and provide points of stress concentrations and crack propagation.
