Supervisor: doc. Ing. Jaroslav Juračka, Ph.D.  
Supervising institute: LÚ all courses guaranted by this institute
Teaching language: English
Aims of the course unit:
The goal is to familiarize students with fundaments of composite materials, their application to structure design, possible technology and basic strength calculation.
Learning outcomes and competences:
Student will gain basic knowledge about composite materials, its application to structure design, technology and strength calculation.
Prerequisites:
Basic knowledge of strength and elastic theory.
Course contents:
Students will be acquainted with fundaments of composite materials, their application to structure design, possible technology and basic strength calculation. Topics of micromechanics, macromechanics, joints, stability, quality assurance, application at structure and testing will be presented.
Teaching methods and criteria:
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures. Teaching is suplemented by practical laboratory work.
Assesment methods and criteria linked to learning outcomes:
Course-unit credit: 90% participation in exercises, completion of all calculated task from exercises. Exam: written test - theoretical background, task calculation
Controlled participation in lessons:
Participation in lectures and exercises. Missed exercises will be compensated by self-study of tasks.
