Description:
The present article offers a modified method of friction stir process combined with ultrasonic vibrations in order to reinforce polyamide 6 (PA 6) using multi-walled carbon nanotubes (MWCNT). For this purpose, ultrasonic-assisted friction stir process and simple friction stir process were performed to distribute the MWCNT particles among the PA 6. Field emission type of scanning electron microscopy, X-ray diffraction, Vickers’ micro-hardness, and visual inspection were used to evaluate and compare properties of the fabricated nano-composites. According to the findings, increase of traverse speed leads to increase of the stir intensified by the energy imposed by ultrasonic vibrations during ultrasonic-assisted friction stir process (UAFSP). On the other hand, energy imposed by ultrasonic vibrations accelerates nano-composite fabrication process without affecting dispersion, homogeneity, and hardness. In other words, nano-composite could be fabricated by higher traverse speed without reduction of stirring during UAFSP.
