Abstract
In this study, the effects of nanoclay content, rotational speed, and processing temperature on the mechanical properties and thickness uniformity of produced polymeric samples are investigated using rotational molding process. For this purpose, the design of experiments is used according to the L9 orthogonal array of Taguchi approach. Tensile strength, Young’s modulus, hardness, and standard deviation of thickness are considered as different criteria. The results indicate that increasing temperature increases tensile strength and Young’s modulus of nanocomposite samples by 21 and 31%, respectively. Also, the hardness of specimens is increased almost 6% by increasing nanoclay. The thickness uniformity of samples is also improved significantly by increasing nanoclay and processing temperature. Finally, a simultaneous decision analysis is performed and the best sample is selected with respect to the considered criteria using multi-criteria decision making methods. The results illustrate that nanocomposite samples with 1 wt % nanoclay and produced in rotational speed of 23 rpm and temperature of 205°C are the best samples.
