Learning Objectives
The course will illustrate the physico-chemical and mechanical properties of composite materials, their main industrial technologies for manufacturing and the characteristics of other innovative materials. The students will be able to basically design composite materials as a function of required mechanical properties (elastic modulus, strength) under simple stress conditions, and to select suitable advanced materials and manufacturing technologies for a specific product.
Prerequisites
Basic knowledge of materials. Knowledge of mechanical properties of materials. Knowledge of traditional materials: metals, ceramics and polymers. Basic knowledge of chemistry, physics and mathematics.
Teaching Methods
Ex-cathedra lessons
Further information
The slides shown at the lessons and other teaching aids will be uploaded on the Course homepage on the site e-l.unifi.it
Type of Assessment
The student shall prove to know:
- the characteristics of composite materials;
- the different materials used in composite materials;
- the manufacturing technologies used for composite materials;
- the characteristics of the other innovative materials treated during the course.
The student shall prove also to solve an exercise regarding the physical (density) and mechanical properties of fiber composites.
Examination method:
- written examination (given time: 1 h 30 min) consisting in 6 open-ended questions, for which a synthetic report must be given, regarding the program treated during the course, and an exercise.
The on-line registration on the examination site of the is required to access the examination.
