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, an to select suitable advanced materials and manufacturing technologies for a specific product.
Prerequisites
