Hybrid Solutions for Joints in Carbon Composite Structures
Carbon composite materials are applied in aircraft structures because of their high specific strength and stiffness. However, for some load cases these composites are less favorable, e.g. at mechanical joints and on impact. Properties related to these loads can be improved by local hybridization, i.e. by local metal layer inserts in the carbon composites. This paper focuses on the improvement of the bolted joint strength by metal layer substitution. The performance depends on the joint design and the design of the transition area between joint and composite laminate. Results show that significant improvements can be achieved.
