The course aims to allow students to acquire knowledge and skills useful for the virtuous circle of innovation-technologies-materials-products-processes in the structural and propulsive aeronautics sector and in the broader field of manufacturing industry. The topics will be treated with the use of an inter- and multidisciplinary approach, with the aim of linking knowledge and skills relating to the development and use of innovative materials technologies, aimed at implementation applications and selection / project aspects. The basic aspects aimed at identifying criteria for the selection and choice of materials that favor manufacturing approaches typical of the circular economy will also be highlighted, with reference to the use of environmentally friendly and recyclable materials, for technological processes also based on replacement materials from raw materials, including light and multi-material systems.
