Adhesive bonding technology for new material combinations and load-bearing structures
Modern lightweight construction methods have revolutionized vehicle manufacturing in the recent past. Whether ships, aircraft, automobiles or rail vehicles, or heavy steel construction, the use of the most suitable materials has led to remarkable improvements in performance, weight, shape, safety and comfort. At the same time, cost savings have been achieved. Adhesive bonding technology now enables new combinations of materials and allows previously unfeasible combinations of materials – in transport technology, for example, the bonding of glass and steel, aluminum and magnesium, or fiber composites with metal.
Furthermore, additional functions can be integrated via the adhesive, such as vibration damping, electrical insulation or corrosion protection. This extremely flexible joining technology also leads to a significant increase in the rigidity of vehicles. Today, bonded joints meet the most stringent requirements and can be excellently combined with mechanical joining methods such as clinching, riveting, bolting, and also spot welding. Fraunhofer IFAM provides comprehensive advice on the various possible combinations and has the expertise and equipment to test such load-transmitting bonded joints.
