Bachelor's thesis

  • Investigation of adhesion between sizing layer and carbon fiber surface
Fiber surface topography and surface chemistry influence the interaction between the carbon fiber and the resin matrix during composite manufacturing. Polymeric sizing on the fiber strongly interacts with the fiber as well as the matrix and can either improve or adversely affect the fiber-matrix bonding. Hence it is essential to investigate the sizing layer in order to understand its impact on composite properties and performance. This bachelor project focuses on investigating the adhesion between sizing layer and the fiber surface using chemical extraction and thermal desizing methods, followed by microscopic investigations.

  • Non-destructive characterization of Carbon substrates with complex porosity
Liquid Silicon Infiltration (LSI) is one of the key processes for manufacturing Silicon carbide (SiC) matrix composites. This process involves infiltration of porous carbon preforms with molten silicon at high temperatures to form SiC. The kinetics of this infiltration process largely depends on the porosity, pore size and morphology of the carbon substrate. Hence it is critical to characterize the porosity of the carbon preforms in order to understand and predict the LSI process outcome. Objective of this study is to characterize the porosity and pore morphology of given carbon substrate and correlate it with the amount of silicon consumed during infiltration process.

  • Optimization of Electrophoretic deposition parameters

This research project focuses on optimizing the electrophoretic deposition (EPD) process to produce high-quality ceramic coatings. Using a combination of ceramic powders, the project will investigate the role of solvents, dispersants, and process parameters such as voltage and deposition time on the coating quality.

  • Emission measurements for the pyrolysis of phenol-based resins

The chair of Materials Engineering at the MRM is involved in the further development of carbon fiber-reinforced silicon carbide (C/SiC) materials in collaboration with industry partners. With regard to the goal of CO2 neutrality in German industry by 2045, our chair is making a contribution by examining the energy-intensive processing of these materials for possible savings. It is essential to understand how the process control during pyrolysis affects the composition of emissions. This not only allows important conclusions to be drawn for materials research, but also provides insights for environmental accounting. The aim of this work is to enable a quantitative determination of emissions during pyrolysis and to show how the exhaust gas composition changes when the production parameters are adjusted.
