Residual Stresses and Distortions in Fuselage Panels Made of Composite and Hybrid Materials
Dr. Morteza Abouhamzeh
Delft University of Technology, Netherlands
In recent years, extended work is done on design procedure of panels made from composites and hybrid materials. Fibre metal laminates (FMLs) have been proved to have superior structural integrity aspects like fatigue, crack propagation, residual strength, etc. However, the manufacturing procedure and its effects on the performance of the material need to be improved.
A research has been carried out by the “Structural Integrity and Composites (SI&C) group at Delft University of Technology”, where GLARE was actually invented in the past. GLARE is the most currently applied type of FMLs with Aluminium and glass fibres integrated by epoxy. The laminates may be attached together by splices (adhesion of the adjacent laminates to make larger panels). The final panels may have cut-out features and reinforced by attaching doublers and stringers to the already cured laminates which would need a second cure cycle.
Response of the hybrid material is characterised in different circumstances during manufacturing. Models are developed for prediction of residual stresses during the cure cycle of the material.
The focus of this seminar is to give an overview of the details of the performed research on this topic. The characterisation experiments and measurements are described and the developed models are presented. The future research steps are mentioned and the impact of the output of this research on the fuselage industry, using composite and/or hybrid materials in different parts will be discussed.
