Structural bonding is still in its infancy as a joining method in the automotive industry. Modern lightweight construction, safety and modular designs are no longer possible without bonded connections that provide strength if a crash occurs. Structural bonding is becoming increasingly important in vehicle construction. For mixed body construction methods using a combination of different materials such as steel, aluminium, fiber-reinforced plastics and coated panels. Adhesives have clear advantages compared to conventional welding. Special attention must be paid to insulating capability and elasticity when selecting an adhesive. Soft adhesives with a high degree of expansion are extremely suitable for the mixed construction method, and the layer of adhesive should be as thick as possible. Modern body structure bonding also includes additional securing elements such as punch rivets. Combined joining methods significantly increase working capability and therefore crash resistance compared to spot welding. The use of adhesives in the body structure increases the structural rigidity of the bodies by approximately 15 to 30 percent in comparison to welded components. Bonding also improves the operational strength of vehicle structures.
