Development of Innovative and Advanced Laminates for Future Aircraft Structure
The technical focus of this project is the development of new generations of Fibre Metal Laminates-FML and Metal Laminates-ML, that provide significantly improved strength and stiffness properties for tailored fuselage applications. The fatigue properties of these innovative Laminates, which are not yet available, are required to match those of the rather expensive GLARE® material. The objective of significantly increased static behaviour and a well-balanced combination of mechanical properties will be achieved by the use of alternative constituents such as new fibres, advanced metals and modified pre-preg systems. The high manufacturing costs of FML will be reduced by using less expensive material systems such as high performance ML. Appropriate manufacturing and joining technologies require validation for the progressive laminates. Corrosion is a problem to be quantified and resolved with new sizings and treatments. A further essential task is the development of material models and static failure criteria for the prediction of the material behaviour of FML and ML in both the microscopic and the macroscopic scale. Finally, optimisation criteria for the design of coupons and structural elements will be developed and experimentally verified for laminates with the aim to reduce the overall weight of the aircraft fuselage. The technological objective is a fuselage skin weight reduction of up to 30% when compared to GLARE®. This is achieved by an increase in static properties of 10 to 100%, depending on the specific value considered. The strategic objectives are an increase in the operational capacity of 10%, a reduction in the direct operating cost of 10% and finally a reduction in the fuel consumption of 10% and therefore a reduced environmental impact with regard to emissions and noise. The strategic and economic objective is a reduction in the product cost of 5% derived due from a fuselage skin material cost reduction of 20%.
