Abstract: The European aircraft industry has strong interest in novel structural concepts for future aircraft fuselage and wing structures with lower fabrication costs and high performance. An important class of these next generation aerospace materials will employ advanced manufacturing techniques for sandwich structures with cellular core materials giving high strength/weight and improved impact resistance under critical aircraft load cases such as foreign object impact from birds, tyre rubber and runway debris. Sandwich fuselage designs are being used now for small aircraft, such as executive jets, and in helicopters or as secondary structures in wing high lift devices. However, these current aircraft sandwich structures are particularly vulnerable to impact damage, due to their thin composite skins and low strength honeycomb or polymer foam cores. The requirement now is new sandwich material concepts for primary aircraft structures, with higher performance low weight structural cores [1].
