“…However, this Ra value was lower than the CF reinforced PA6 composites. Similarly, while [26], stated that the Ra decrease with CNT addition compared to neat PA6 in their study, [24] found out the increase on PA66 hole quality with the addition of glass fiber whiskers. It was declared that the decrease of Ra was corelated with the heat transformation from drilling region to tool bit and chip [30].…”

Polyamides are preferred polymer materials for manufacturing industrial products due to their lightness, resistance to corrosion, ease of processing, and recyclability. In this study, the machinability properties of Polyamide 6 (PA6) polymer composite plates reinforced with chopped carbon fiber (CF) and multi-walled carbon nanotube (MWCNT) in different proportions were investigated by the drilling method using different cutting tools and cutting parameters. The experiments were carried out according to the L16 orthogonal array. Drilling experiments were carried out in a dry environment. The deformations occurring on the inlet and outlet surfaces of the drilled samples were calculated, and the surface roughness (Ra) of the hole walls was measured. According to the results obtained, the particle addition made to the PA6 polymer reduced the Ra. It has been observed that high cutting speed and low feed rate are ideal parameters to achieve low Ra and low inlet-outlet deformations.

“…On another study according to the findings it is said that tool wear is greater in machining of reinforced Polyamide 6 composite material [25]. [26] investigated the milling of multi-walled carbon nanotube reinforced Polyamide 6 composite. They pointed out the feed rate was most effective parameter on Ra.…”

“…Additionally, Farshbaf Zinati and Razfar [9] numerically modeled FSP of PA 6 to study material flow and strain during FSP. On the other hand, Farshbaf Zinati and Razfar [10] and Farshbaf Zinati et al [11] study machinability of PA 6/MWCNT composite fabricated by FSP. Panneerselvam and Lenin [12] performed FSW on PA 6 to study the effects of FSW parameters on welding quality.…”

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, ultrasonicassisted 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, nanocomposite could be fabricated by higher traverse speed without reduction of stirring during UAFSP.

In this paper, PP/EPDM nanocomposites with 5 wt% nanoclay are fabricated by friction stir processing (FSP) and compared to the results obtained via a conventional twin screw extruder (TSE). Also, the effects of process parameters of these process on morphology and mechanical properties of this nanocomposites are investigated using Taguchi analysis. The prepared PP/EPDM/clay nanocomposites by two methods were characterized using X‐ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), thermogravimetric analysis (TGA) and mechanical property tests. Comparison of the results of these methods indicated that PP/EPDM/clay nanocomposite fabricated by FSP had a better dispersion of nanoclay and mechanical properties. The results show that by addition of 5 wt% nanoclay to the base material, the tensile strength and tensile modulus of FSP sample are 12% and 8% higher than the TSE sample. The TGA results shows that, the temperature at 50% weight loss for PP/EPDM blend is 382°C. While this temperature for TSE and FSP samples are 395°C and 406°C, respectively. Under optimal conditions of rotational speed of 1,200 rpm, traverse speed of 50 mm/min, shoulder temperature of 100°C and number passes of 3, simultaneous maximization of tensile strength (19.35 MPa), tensile modulus (643 MPa), impact strength (63 J/m) and elongation at break (101%) can be obtained.
