Refilled Friction Stir Spot Joining of Aluminum to Polymer Sheets, M.Sc. Thesis Sharif University of Technology ; Kokabi, Amir Hossein (Supervisor) ; Movahedi, Mojtaba (Supervisor)
Abstract
Today, dissimilar joining of metal to polymer is in increasing demand in automotive and aerospace industries. Conventional methods for dissimilar joining of metal to polymer have limitations such as need for complex system and high surface sensitivity. Therefore, in this study, it has been tried to join pre-drilled aluminum sheets to polymer, based on frictional heat and creation of interlocks between the base parts. Refilling the hole is the main advantage of the method. AA5052 sheet with 2 mm thickness and polypropylene reinforced with 3 wt% short-carbon-fiber composite were used as primary materials. The effect of hole diameter in 4 and 5.5 mm and tool rotational speed in 500, 1000, 1500...
