The project aims to develop a new concept in materials design based on assemblies of interlocked elements. Interlocking is achieved topologically by special arrangements of blocks without connectors. Such assemblies can form structures possessing special mechanical properties and serve as load-bearing skeletons in composites with a binder phase providing desired functional properties. Various types of interlocked assemblies will be modelled, produced and tested to determine their mechanical and acoustic properties. A range of experimental techniques tailored for these unusual assemblies will be employed. The expected outcome will be the implementation of the new design principle in multifunctional materials and structures.Read moreRead less
