Basic knowledge on chemistry and physics.

Learning outcomes
The course enables students to acquire advanced knowledge on the main characteristics of three kinds of materials: metals, polymers and ceramics. Such knowledge, by integrating that acquired on the course of metallurgy, will be a deepening, which should increase the knowledge on the materials' technology sector. In this way, the student will acquire clear awareness of the wider multidisciplinary contest of engineering, with clear reference to aspects directly related to production systems and technologies
In order to address advanced design themes and treat the innovation and development of new products and new technological processes through the application of knowledge, the student should be able to correctly interpret the structural behaviour of materials as well as the related technological aspects already analysed in other courses and usually encountered in the engineering practice. This will be reflected in a range of professional skills, such as: 1. the ability to choose the most suitable material in relation to the required properties; 2. the ability to correlate the materials' structure with their mechanical properties
The problem solving will contribute to improve the independent judgement skills of the students, the communication skills as well as their ability to learn and draw conclusions.

Classification of materials. The solid state: crystalline and amorphous structure. Materials properties: microstructure, porosity, density, mechanical properties and thermal properties. Main properties of metals depending on their microstructure. Ceramic materials: silicates structure and fundamental concepts on clay and clay minerals. Traditional and innovative ceramics and their crystalline structure. Silica glasses. Technology of production of glasses and ceramics. Binders. Polymers: monomers, polymers, copolymers. Degree of polymerization and number-average molecular weight. Addition polymerisation. Stereoisomerism. Polymer structure: amorphous and crystalline state. Structure and properties of the thermoplastic polymers obtained by means of the addition polymerization. Poly-condensation reaction: synthesis of nylon 6,6 and polyethylene terephthalate (PET). Structure and properties of thermoplastic and thermosetting polymers obtained by means of the condensation polymerization. Industrial methods for polymerisation. Processing of thermoplastic and thermosetting polymers. Creep of polymer materials. Fracture of polymer materials. Aging of polymer materials. Elastomers: natural rubber and SBR rubbler and vulcanization process. Structure of composite materials: matrix and reinforcing material. Composite materials durability. Polymer-, metal- and ceramic-based composites. Wood. Ageing, corrosion and deterioration of materials. Metals, polymers and ceramics deterioration. Deterioration causes of cement-based materials.

Development of the examination
The exam will consist of an oral examination, in which the topics of the course will be discussed; it will consist of three questions related to three different topics among them illustreted in the course.

During the oral examination, the candidate should exhibit a proper knowledge of the properties, behaviour, production technology and applications of the different classes of materials.The student will get maximum score if able to show deep knowledge on the varior topics of the course as well as if able to coherently describe concepts.

A score will be attributed to each of the three questions with a grading scheme based on a scale of 30 points: 0 score menas question not answered; 18 score means sufficently answered question, while 30 score means fully answered question; intermediate scores as a consequence.

The final grade (to a maximum scale of thirty) will be the mean value of the scores obtained for each answer. The mean value will be calculated on three answers, but if the difference in the scores is higher than 10, a fourth question will be made and the final score will be the mean value calculated on four scores, the last included.
