Teaching Methods
THE COURSE CONSISTS IN FRONT LESSONS (47H), CLASSROOM EXERCISES (6H) AND ACTIVITIES IN LAB (7H) FOR A TOTAL AMOUNT OF 60 HOURS (6 CFU). DURING LABORATORY WORK, THERMAL AND MECHANICAL TESTS WILL BE SHOWN TO THE STUDENTS. MOREOVER THEY WILL ASSIST TO THE PRODUCTION OF PROTOTYPE USING DIFFERENT PROCESSING TECHNOLOGIES (EXTRUSION FILM, COMPOUNDING, COEXTRUSION AND INJECTION MOLDING) USING LABORATORY SCALE PLANT.
ATTENDANCE AT THE LECTURES IS STRONGLY RECOMMENDED
Verification of learning
THE ASSESSMENT OF THE ACHIEVEMENT OF THE OBJECTIVES WILL BE DONE THROUGH AN ORAL INTERVIEW DURING WHICH WILL BE VERIFIED: THE LEVEL OF KNOWLEDGE, THE CORRECTNESS OF EXPRESSION AND TERMINOLOGY USED AND THE ABILITY TO APPLY THE KNOWLEDGE TO SIMPLE REAL EXAMPLES.
THE INTERVIEW LASTS ABOUT 40MIN.
THE FINAL VOTE IS EXPRESSED IN A SCALE FROM 1 TO 30, WITH A PASS GRADE EQUAL TO 18.
IN ORDER TO PASS THE EXAMINATION STUDENTS MUST DEMONSTRATE AT LEAST THAT THEY ARE ABLE TO MAKE A CORRECT CHOICE OF THE MOST SUITABLE POLYMER AND PROCESSING TECHNOLOGY FOR THE PRODUCTION OF A SPECIFIC PRODUCT, ACCORDING TO THE MELT AND SOLID STATE PROPERTIES OF THE POLYMER.
THE LEVEL OF EXCELLENCE (I.E. THE SCORE 30/30) CAN BE ACHIEVED BY THE STUDENTS WHO DEMONSTRATE TO BE ABLE TO DEAL WITH NON STANDARD PROBLEMS OR NOT SPECIFICALLY PRESENTED IN CLASS WITH PARTICULAR REGARD TO THE CORRECT APPLICATION OF CORRELATIONS BETWEEN STRUCTURE, PROCESS, PROPERTY AND RECYCLABILITY OF POLYMERIC MATERIALS PRESENTED DURING THE COURSE.
