The Laboratory of Composite Materials and Adaptive Structuresat the Department of Mechanical and Process Engineering, ETH Zurich, invites applications for a
PhD position in Measurements and Modelling of Unsaturated Out-of-Plane Permeability of Engineering Textiles
Materials and structuresare contributing to the efficiency, functionality and safety of technical products. Our vision is to promote science and innovation by exploring the relation between materials, manufacturing and design of structural systems. In Liquid Composite Moulding (LCM) processes, fast textile impregnation techniques often rely on out-of-plane injection strategies. This permits to increase production rates and further enhance the competitiveness and economical viability of lightweight composites solutions. Modeling and simulation of out-of-plane impregnation processes are generally very complex, because of the strong coupling between the resin flow and the fibre bed deformation.
The objective of this project is to investigate the underlying mechanisms and to develop reliable methods and tools for the characterization of the unsaturated out-of-plane permeability of engineering textiles. We plan to combine analytical and numerical investigations with original experimental methods, including flow and ply displacement monitoring techniques.
To address this challenging task, TU Kaiserslautern (Institute für Verbundwerkstoffe) and ETH Zürich (Laboratory of Composite Materials and Adaptive Structures) have decided to join forces, sharing their complementary knowledge and expertise. IVW will concentrate on the experimental investigations, including the development and the realization of the measurement cell and carry out flow experiments under different conditions. CMASLab will develop numerical methods and tools to model the fluid flow and textile deformation in the out-of-plane impregnation process and to derive a unique value of the unsaturated textile permeability based on experimental data.
To be successfulthe PhD candidate must have an excellent Masters degree in Mechanical, Process, or Materials Engineering from a reputable university with international standing. He/she must possess excellent analytical skills, the ability to think critically, and attention to detail. He/she must be able to work independently, to meet scheduled deadlines and milestones. Besides he/she should be familiar with mathematical, modelling, and design software like Matlab, LabVIEW, COMOSL and NX. He/she should have practical experience with processing of fibre-reinforced composite materials with different manufacturing methods (wet lamination, Liquid Composite Molding, prepreg, … ) and have the desire to perform laboratory and experimental work, plan and carry out characterization and validation experiments. The successful candidate will be expected to contribute to activities of the chair with respect to teaching and general support. We are looking for a candidate that is available as soon as possible to begin this project.
