Processing of Nonmetallic Materials (FSI-WNK-A)

Academic year 2020/2021

Supervisor:	prof. Ing. Martin Trunec, Dr.
Supervising institute:	ÚMVI	all courses guaranted by this institute
Teaching language:	English
Aims of the course unit:
The aim of the course is to present the basic overview of methods for advanced non-metallic materials processing. Students will learn of principles of particular methods and of their relation to the materials.
Learning outcomes and competences:
Participants of the course will be able to analyse processing needs of particular materials and select the appropriate processing method for a selected application.
Prerequisites:
Students have to prove the knowledge of structure and properties of non-metallic materials. Knowledge of chemistry is assumed on the secondary school level enhanced by basic knowledge of surface chemistry (surface and interparticle forces).
Course contents:
This course deals with the technology basics of advanced ceramics, glass-ceramics and plastics. The emphasis is put on technology principles of particular classes of materials. Processing methods are discussed with respect to the nature and properties of materials. The course includes an overview of processing of ceramics-ceramics composites, glass-ceramics composites and ceramics-metal composites.
Teaching methods and criteria:
The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical laboratory work.
Assesment methods and criteria linked to learning outcomes:
Graded course-unit credit requirements: Examination will be carried out in the way of discussion with the student. During the discussion students will prove the knowledge of principles of non-metallic materials processing methods. Each student will get a selected product of non-metallic material with a brief material and purpose descriptions. In the following discussion students have to be able to choose an appropriate fabrication method. This method has to be described and justified.
Controlled participation in lessons:
The presence of students at lessons will be checked. Compensation for missed lessons will be solved case by case.
