Please note: This course will be offered during the first AND second quartile
After the course the student is able to:
- Derive the properties of a continuous fibre reinforced composite ply as a function of its constituents and their fractions
- Determine and analyse the stress – deformation relation of a continuous fibre reinforced composite ply for varying fibre orientation
- Derive and analyse the loading – deformation relation of a laminated plate
- Classify the way composite materials fail and quantify first-ply failure in a laminate
- Choose and advise on manufacturing technologies (for a given set of requirements on the part to be made)
- Design a lay-up for plate- or cylinder-like composite structures given the loading requirements

Course Description
The Composites course gives an introduction into the mechanical behaviour of continuous fibre reinforced composites and their manufacturing processes. The composite materials considered are layered structures (laminates) built from thin fibre reinforced polymer layers (laminae). The fibre orientation is usually chosen to match the loading direction. As a result, the material obtained is tailor-made, but also highly anisotropic. Moreover, the heterogeneous nature of composite makes them different from conventional materials in terms of processing.
The lectures mainly deal with the Classical Lamination Theory, which can be used to describe the response of a composite laminate to thermo-mechanical loading. The theory starts from micromechanics to describe the properties of a single layer based on the fibre and polymer properties and their content fractions. Subsequently, the behaviour of a laminate, which is created by stacking several layers in different orientations, can be described using the Classical Lamination Theory. Finally, the failure resistance of composite materials is highlighted. Apart from the mechanical behaviour of laminates, the lectures will also address composite applications, materials, and manufacturing methods.
The course gives the opportunity to apply the obtained knowledge during practical exercises, involving for example the design of a composite drive shaft or a hydrogen storage tank. Additionally, there will be a lab activity on the topic of composite manufacturing or mechanical testing.
