Learning Objectives

• Macromolecular chemistry
  

  The course aims to provide the student with the notions relating to the relationships between the structure of polymeric materials and their mechanical properties, their transformation technologies and the problems relating to their production.

• MATERIALS SCIENCE AND TECHNOLOGY
  
  • Knowledge and understanding: Basic knowledge of materials of interest for mechanical engineering, correlating their application characteristics to composition, structure, production and processing technologies
  • Applied knowledge and understanding skills: Ability to apply what has been learned during the lectures in the exercises carried out during the course.
  • Independent judgment: Students learn to objectively evaluate what they have learned during lessons and exercises.
  • Communication skills: Students acquire communication skills that are formed both during the lessons, thanks to a continuous verbal conversation with the lecturer, and during the oral exams.
  • Learning skills: Learning skills are assessed through the oral exam and exercises which are an important part of the course.
