Programma dettagliato e risultati di apprendimento attesi


Course goals and contents
The course is aimed to students following higher degree programs (Laurea magistrale) in Aeronautical Engineering, Space Engineering, Mechanical Enginering and Materisl Engineering willing to complete their knowledge with concepts of structural mechanics, materials science and technology, which were introduced in previous courses (as for example Tecnologie e Materiali Aerospaziali I). Particular attention will be given to special materials and technologies for aerospace applications (advanced composites, materials for gossamer structures and propellants, thermal protections, sandwich and morphing structures). Moreover, innovative materials and technologies (smart materials, self-healing and bio-mimetic materials, micro and nano materials and related technologies – MEMS, NEMS, rapid prototyping) will be presented and discussed.
Consideration will be given to aspects related to air/spacecraft operations such as functional degradation, damage inspection and repair techniques
