Název v původním jazyce

Fatigue Behaviour and Damage Tolerant Design of Composite Bonded Joints For Aerospace Application

Popis výsledku v původním jazyce

Today the application of bonding technology for primary aerospace structures is limited due to the certification guidelines and standard means of comply. State of the art is the widely used chicken rivet which is limiting the benefits of the application of composite bonded joints due to thickness requirements for the bolt. This paper will give an overview of the current research conducted within the European project BOPACS. The project is focussing directly on the application of Means of Compliance within AC-20-107B by investigating crack arrest by design features. Derived from the conclusion of the Cracked Lap Shear (CLS) Coupon, the Wide Single Lap Shear (WSLS) Specimen has been developed. It marks the next level test setup beyond the basic coupon level for demonstration and investigation of crack growth behavior in bonded joints. This specimen is representing the generic geometrical condition of a high load transfer (HLT) joint, representing e.g. a fuselage panel joint. The basic layout of the specimen and first results of the current test program as well as the specifics for the test setup and data acquisition strategy is discussed. Results from the running test program are presented and the influence of individual test parameters highlighted. Finally, the influence on a certification strategy for structural bonding is outlined.
