| Abstract | ||
| This study aims to improve the tribological properties of high-density polyethylene (HDPE) by adding CNTs. Cylindrical samples were prepared with 0.1-0.5% by weight of SWCNTs and MWCNTs nanoparticles. The samples were tested for friction coefficient and wear rate using a pin on disk. Moreover, the mechanical properties were evaluated by measuring the density and hardness of the samples. The study found that the mechanical and tribological properties of HDPE composites were significantly improved. The best tribological properties were observed in the HDPE nanocomposite sample with 0.5 wt. % SWCNTs and 0.2 wt. % MWCNTs, resulting in a reduced friction coefficient and wear rate. | ||
