“…Liu et al reported that for CNT/ 2009 Al, dispersion of individual CNTs was achieved in multiple passes FSP. Increasing rotational speed increases shear stress and consequently dispersion of clay nanoparticles in base material can be obtained . The mixing time in the processed zone decreases with increasing the traverse speed which causes lower dispersion of nanoclay in the TPO matrix and it also decreases the tensile strength and tensile modulus while enhancing impact strength and elongation at break .…”

“…They concluded that the FSP is a suitable method for fabricating thermoplastic composite and nanocomposites. Their results showed that the surface appearance and mechanical properties of composite and nanocomposites are strongly affected by FSP parameters such as rotational speed, traverse speed and shoulder temperature . In this study, FSP and twin screw extruder (TSE) were employed to fabricated PP/EPDM/clay nanocomposites.…”

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.

Aluminum proved its effective usage in various applications because of its light weight and high strength. This work highly focused on fabrication of aluminum alloy Al7075 with addition of (10 wt. %) of silicon carbide (SiC) and (10 wt. %) graphite (Gr) by using friction stir processing. Initially reinforcement distribution examined by using SEM and EDS analysis. Co efficient of friction and wear was examined by pin on disc Tribometer. Based on the experimental results, improved mechanical properties and tribological properties were obtained compare to the base metal Al7075 aluminum alloy.

“…It was found that the TiC particles were segregated at the grain boundaries in the as-cast material, which were nearly uniformly distributed within the matrix after two-pass FSP. Barmouz et al [15] produced polymer nanocomposites by in-situ dispersion of clay particles via FSP. Mahmoud et al [16] studied the wear characteristics of surface-hybrid-MMCs layer fabricated on an aluminium plate using FSP.…”

Composite reinforcement manufacturing is gaining the attention of many researchers because it enhances the physical and chemical properties of the material that it is reinforced into. In this research, friction stir processing (FSP) was used to modify the surface by reinforcing titanium dioxide on aluminium alloy AA 5052. In this process, a square pin of length of edges of 6 mm was used. The experiment was done under variable parameters, namely, speed of the spindle rotation, processing feed rate on the milling machine and groove width of the sample. The groove on aluminium alloy was made to store the nanoparticles before FSP. The resultant reinforced material had increased mechanical properties compared to the aluminium alloy without FSP. This was due to the presence of hard particles. Titanium dioxide nanoparticles were seen in the grain structure of the aluminium alloy which enhanced the properties of the material surface. This research was done to study the manufacturing process and the material integrity for various applications.
