Cellular Structures for Impact Performance

Objective

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. The main objective of the project is development and design of cellular materials and twin skinned sandwich structures made from hybrid composites and metals. CELPACT will progress fabrication technology for cellular metals based on selective laser melting and develop new fabrication concepts for hybrid composite sandwich structures with folded cellular composite cores. Computational methods will be developed based on micromechanics cell models with multiscale modelling techniques for understanding progressive damage and collapse mechanisms and used for structural analysis. Impact performance is critical for sandwich aircraft structures and the simulation tools will be used to design efficient impact resistant aircraft structures. Structural integrity of these advanced cellular structures will be assessed by testing generic cellular beam and shell structures under high velocity impact conditions relevant to aircraft structures. CELPACT is an upstream research project concerned with development of breakthrough technologies and design tools for future airframe structures with high efficiency and safety. It has been prioritised by the European Aeronautical Scientific Network EASN. The consortium from five European countries contains seven leading universities with research institutes and aircraft industry partners.
