In modern lightweight structures different requirements for components occur. In many cases they cannot be fulfilled by a single material in an optimum way. Therefore, the use of different materials with different properties is desirable. The combination of CFRP (carbon fibre reinforced plastics) and aluminium alloys is promising for structural components with regard to lightweight design. The materials are joined conventionally by riveting or adhesive bonding. However, these joining methods lead to a weakened region in the load path and a bulky design. The researcher group “Schwarz‐Silber” (FOR 1224), founded by the DFG (German Research‐Foundation), investigates new interface structures for advanced carbon fibre reinforced plastics‐aluminium compounds in five interdisciplinary projects. This paper deals with the strength and the failure behaviour of three differently manufactured carbon fibre reinforced plastics‐aluminium seam structures under tensile loading. Due to the contact of the seam structures to the carbon fibre reinforced plastics as well as to the aluminium part each connection consists of two joining areas which may act as the weak point of the connection.
