Praktikum Faserverbundwerkstoffe

After participating in the course, students will be able to distinguish between the variety of different matrix systems and fiber types and to make application-specific selections.

The practical course 'Composite Materials' teaches different systems of carbon fiber reinforced polymers (CFRP) and the different manufacturing processes for fiber composites. The entire process chain from concept to simulation to the test bench is covered. Specific topics are: - Basics of fiber composite manufacturing. - Material properties and usability of fiber composites. - Potential of hybrid construction methods and natural fibers. - Basics of mold construction from metal, wood, foam and plastic materials. - Prototyping design, taking into account requirements such as weight and deformation stability. - Manufacturing of a prototype. - Setup of a measurement chain to verify the mechanical properties of the prototype. - Planning and execution of a test, as well as documentation and presentation of the results. - Application areas from: Aerospace, automotive industry, sports and leisure, robotics, medical technology.

Lecture Lightweight Design

The basic knowledge of materials, fiber types, matrix systems and manufacturing processes for CFRP components is imparted at the beginning of the event with the help of lectures. A safety briefing trains the participants with regard to the safety-critical aspects and enables the students to work independently with the materials and equipment. The conceptual design of the components, the design and calculation with regard to mold design and manufacturability as well as the planning of the test arrangements and the types of load cases are carried out in group work in order to enable mutual learning and to increase the exchange of experience and knowledge. The groups are supervised by experienced employees. Component fabrication is carried out under the supervision of our staff to provide students with practical experience that will later help in the application-specific selection of fiber types and matrix systems as well as fabrication processes. In a final component test and presentation of results, the participants must document and communicate their findings, which promotes knowledge sharing and collaboration skills.

The exam consists of the project work, a written report and a presentation: - Project result (40%) Designed and manufactured component - Written report (40%) (approx. 10 pages) to test skills in selection and use of fiber types and matrix structures and calculation of component characteristics. - Presentation (20%) (approx. 20 min. + questions) to test understanding and communication skills of CFRP materials and manufacturing processes.
