Learning outcomes |
- To acquire scientific and technological knowledge about the different classes of materials used in industry, particularly in the mobility and energy sectors.
- To understand the properties to know the nomenclature and be able to give examples and applications of the main metal alloys, polymers, ceramics and composite materials, with an emphasis on steels, light alloys, engineering polymers and structural composites.
- To understand the reasons for the sustainable use of materials, supply risks, the importance of the circular economy and resource recovery.

Teaching Methodologies and Assessment Criteria |
Two hours of lectures are given each week, with slides prepared with didactic content being made available, and one hour of classes with the resolution of selected exercises of increasing difficulty in order to understand the interdependence of the properties of crystalline structure materials and improvement treatments. Use of material property databases and training in learning technical language to understand the respective magnitudes of values.
Carrying out two laboratory assignments (TLab1 and TLab2), in groups and with a report, encouraging the learning of “know-how” through contact with different materials: metals, polymers, ceramics and composites; TLab1: Analysis of their elastic and elastoplastic behaviour through static tests. Comparison of results between different materials and with the literature. TLab2: Getting to use the raw materials and manufacturing techniques for composites incorporating recycled materials. Analysing properties.
