Initial situation:
In the field of aerospace technology, the topic of functional integration is playing an increasingly important role in the development of new products. The aim is to reduce the number of components and production steps by allowing individual components to fulfil several functions. Fibre composites often form the basis of high-strength structures. At the same time, the demand for electrical and electronic functions in aircraft is increasing.
As part of a research collaboration with renowned industrial partners, the Wehrwissenschaftliches Institut für Werk- und Betriebsstoffe (WIWeB) is working together with the Institut für Leichtbau (LRT6) to investigate the processing of functionalised fibre-reinforced plastics (FRP). The aim of the current research is to integrate electrically conductive layers in the fibre composite that can be used for various applications. For this purpose, semi-finished products are printed and integrated into the fibre composite structure. Initial printing tests with subsequent integration into fibre composites have been carried out and the electrical properties are to be tested and optimised in the future.
The aim of the work is to determine the electrical resistance of the film as a function of temperature, process pressure and ink in order to adjust the resistance of the composite. The first step is to print different films with different inks and determine their resistance. These are then measured in a hot press at different parameters. In addition to different methods of resistance measurement, the deformation caused by the pressing process will also be determined using a laser scanning microscope and SEM.
The work takes place both at the UniBw in Neubiberg and at the WIWeB site in Erding. The following work items (WPs) form the content of the work:
- WP1: Literature research in the field of screen printing and planning the test series
- WP2: Carrying out preliminary tests to test the test setup
- WP3: Production of the printed films
- WP4: Carrying out tests on the hot press
- WP5: Analysing the measurement results
- WP6: Documenting the results
