Today, the application of bonding technology for primary aerospace structures is limited due to the certification regulations. State of the art is an additional application of fasteners which is limiting the benefits of the application of composite bonded joints. This paper will give an overview of the current state of the art of certification compliance within the context of bonded CFRP primary structures. Beginning with the boundary conditions and the background of the certification regulations the current framework for the development of composite bonded joints is described including the experiences within the aerospace industry as well as the physical principles that are leading to initial damages and uncertainties within a composite bonded joint. Also the role and interaction of different technology streams like surface preparation, process capability, material & adhesive development and design & sizing concepts to enable a secured roadmap to certification is discussed. The resulting needs for current and future technology development and their interaction within the different disciplines is described. Also solution approaches to build a roadmap to certification of CFRP-bonded joints are highlighted.
