OVERVIEW

In this course the concepts for the understanding the viscoelastic behaviors of the polymeric materials, their implications in the production processes and their correlation between molecular characteristics and physical-mechanical properties, are provided. The rheological, mechanical and dynamic mechanical properties of polymers and their composites are described in detail.

AIMS AND CONTENT

LEARNING OUTCOMES

Molecular understanding of the origin of the structural and mechanical properties of polymer matrices
Knowledge of the basic concepts of composite materials and nano polymer composites.
Understanding of the correlations between structure and properties of polymers and composites and nanocomposites polymer matrix.

AIMS AND LEARNING OUTCOMES

The course is focused to develop the student's ability to correlate the theoretical notions on polymeric materials with experimental data to formulate general criteria for their characterization and use. To pursue this goal, traditional lectures are always accompanied by concrete examples related to everyday life as well as industrial practice. At the end of the course the student will be able to:

• correlate the chemical-physical, mechanical and rheological properties of polymeric materials and their composites to their composition and structure;

• identify and critically discuss the data available from mechanical, dynamical-mechanical and rheological characterization techniques of polymeric materials.

TEACHING METHODS

Traditional lectures sometimes accompanied with exercises carried out by the teacher in the classroom. Lesson notes are uploaded to the corresponding AulaWeb page simultaneously with their presentation in the classroom

EXAMS

EXAM DESCRIPTION

Oral examination conducted by two teachers for a duration of at least 30 minutes.

During the calendar year, seven exam dates are set up in the time intervals scheduled by the Manifesto degli Studi.

The oral examination usually consists of three parts, which of them are evaluated as specified below:

- in the first part, the student has to face a problem with the use of polymeric materials and composites for structural applications in order to verify his understanding and mastery of the course topics as well as his ability to apply the theoretical concepts to real situations; the first part is awarded a maximum rating of 15/30;

- in the second part, the student is required to describe in detail a characterization technique or a property-structure correlation model; the second part is awarded a maximum rating of 10/30;

- in the third part, the student is asked to describe the characteristics and main application areas of thermoset polymers for special applications; the third part is awarded a maximum rating of 5/30.

ASSESSMENT METHODS

The oral examination is conducted by two professors. They are able to verify the achievement of the learning outcomes. When these are not met, the student is invited to extend the study. To ensure uniformity between the examination topics and those actually carried out during the course, is present into the AulaWeb page a detailed program, so that students themselves can verify adherence.
