composite structures fibre angles laminates multi-level optimization buckling Aircraft composite fuselage optimization through barrel and panel level analyses Composite fuselage fiber angle optimization procedure of a window panel region through global and local level models (upper pictures). The discrete tow paths are determined for the resulting optimized fiber angle fields for one of the plies in the global and local models (lower pictures). Problem area International competition urges aeronautic industry in the Netherlands, as supplier for Airbus, to continuously enhance its performance in the engineering design process. The application of novel materials and innovative design methods is of key importance for the further reduction of design time and increased design confidence level. Composite materials are increasingly used on business jets, regional and commercial aircraft. Composite materials provide higher stiffness and strength to density ratios than metallic ones. They permit the design of more integrated structures, with fewer fasteners. They are less prone to progressive damage under in-service fatigue loads with current design rules and are also less sensitive to corrosion
