Due to the low weight and chemical resistance of polymers compared to metals, the use of these materials in various industries has increased. On the other hand, due to the low strength of polymers, their reinforcement with micron and nano particles is necessary. In recent years, one of the advances in plastic and composite industries has been the development and commodification of polymer-based nanocomposites. The use of polymer blend nanocomposites base on thermoplastic polyolefin have interest for engineering application such as automotive, airplane, household appliances and medical apparatus. There are different processes such as extruder and internal mixer to fabricate nanocomposites. The limitation of these processes is the high cost, the multi-stage process for sheet production and the amount of nano-sized reinforcement particles (at most 5 % wt). Recently, investigations have been done on friction stir processing for the fabrication of composites and nanocomposites. To produce polymer composites and nanocomposites with friction stir process, a groove with defined dimensions is machined in the base polymer sheet and nanoparticles are improvised into this groove. Subsequently, a rotating tool is plunged into the sheet and traversed along the groove to disperse particles to the base material.
