| Abstract | ||
| ABSTRACT Graphene oxide (GO) is favored as a filler material in polymer matrix composites because it has higher aspect ratios than many nanosize fillers, such as carbon nanotubes, in addition to having better mechanical qualities than many polymers. In this study, the tribological properties of high density polyethylene (HDPE) were experimentally studied in relation to the effects of GO nanoparticles and vegetables oils. By using the melt compounding process, the nanocomposites (HDPE – GO - vegetables oils) were manufactured. The molded nanocomposite were then tested for friction and wear tests. According to the findings, the addition of GO improved the friction and wear behavior of the composites. With GO loading fractions of 0, 0.06, 0.12, 0.25, 0.5, and 1.0 wt. %, the wear and coefficient of friction values were drastically reduced. The corn and olive oils were added by 10 wt. % to the composites. | ||
