Advanced Polymer-Metal Hybrid Structures
The development of new materials and fabrication techniques has become a matter of success for different industries, such as transportation, medical appliances and civil engineering. The development of new lightweight alloys, such as aluminium, magnesium and titanium, as well as of advanced polymer-based materials, such as Fiber Reinforced Plastics (FRP) and nanocomposites, has changed the current paradigm in the design of lightweight constructions.
In this way, advanced engineered composites are being increasingly mixed with lightweight metals aiming to increase the weight-to-strength structural performance of transportation components for reducing fuel consumption and gas emission. Therefore, alternative and advanced joining technologies are required to to join such multi-material structures.
Joining Dissimilar Materials
Prize winning joining techniques recently developed at Helmholtz-Zentrum Geesthacht (HZG), such as FricRiveting, Injection Clinching Joining (ICJ) and Friction Spot Welding/Joining (FSpW/J) have been devised in order to try to overcome or attenuate the limitations found in current polymer-metal joining methods.
In this way, the performance of polymer-metal hybrid components fabricated by these new joining technologies could be improved in a reliable, faster and more environmental friendly manner. Therefore the Young Investigator Group “Advanced Polymer-Metal Hybrid Structures” aims to face the scientific and technological challenges involved in joining the new polymer-metal hybrid structures in engineering applications.
