Teaching description
knowledge of solid mechanics and materials science and technology
This course is aimed at providing the basics of composites and nanocomposites materials in view of their application in different engineering fields, using a strong interdisciplinary approach. Competences on polymer matrices and reinforcements, mechanics of anisotropic materials, fabrication technologies of thermoplastic and thermosetting matrix composites are provided.
Knowledge and understanding:
The course provides the basis of knowledge to understand and solve complex new problems in design and processing of composite materials accounting for anisotropy and reactive processing
Applying knowledge and understanding
The student will be able to apply the basic knowledge on mechanics of anisotropic materials to the design of simple structural elements. A multidisciplinary approach is presented accounting for chemical, materials and mechanical engineering aspects.
Making judgements
Simplification and synthesis of complex problems is presented in order to promote the judgement and evaluation capabilities of the students
Communication
The course promotes the development of the following skills of the student: ability to expose in precise and formal terms an abstract model of concrete problems, identifying the salient characteristics of them and discarding the inessential characteristics; ability to describe and analyze an efficient solution for the problem under consideration. A seminar on composite properties is assigned to students
Learning skills
Autonomous learning is promoted thanks to the use of: different books and slides, numerical methods, homework exercise to be solved in groups of two.
The course is made up of frontal lessons for about 45 hours, and about 10 hours practice with a software implementing micro and macromechanic of composite materials. 10 more hours of laboratory are foreseen, in order to highlight the relevance of anisotropy in mechanical testing, and provide a practical demonstration of the main technologies for composite processing
