Project Description and Objectives:
The joining between polymer and metal has attracted significant attention recently due to its advantage of excellent integrated physical and chemical properties. There is an increasing demand for high quality metal-polymer hybrid structures in biomedical industries. Friction stir welding (FSW) has advantages in the joining between metal and polymer materials and has been proven to be a suitable technology to produce dissimilar metal-polymer overlapping joints. In this project, we will complete the realization and optimization of the joining process between metal and polymer. The welding temperature (TW) and axial load (FZ) evolution will be measured during welding to study the temperature-force coupling process. A lot of focus will be put into the bonding mechanisms (including macroscopic interlocking mechanism and microscopic bonding mechanism) and their effects on the mechanical properties of the joints which are studied through the Transmission Electron Microscope (TEM), X-ray Photoelectron Spectroscopy (XPS), Fourier Transform Infrared Spectroscopy (FTIR) and Electron Energy Loss Spectroscopy (EELS). The obtained results will fulfill the urgent needs of polymer/metal joints in biomedical applications and also contribute to the understanding and further development of FSW and other welding methods for joining metals and polymers together.
