Optimisation of the process route for the production of particle-filled fibre-matrix semi-finished products

At the Wehrwissenschaftliches Institut für Werk- und Betriebsstoffe (WIWeB), research is being conducted into the introduction of fillers into fibre-reinforced plastics (FRP) to produce new radar-absorbing materials. In the existing process, the fillers are introduced into a continuous glass fibre roving using a wet infiltration process, then dried and wound up. In a continuous subsequent process, the filled roving is impregnated with an epoxy resin matrix and further processed into a semi-finished product. One aim of the research project is to understand the influence of the particles on the electromagnetic and mechanical properties of the FRP. The selected manufacturing process plays a central role in this.


The core of this work is the systematic investigation and optimisation of production parameters (DoE) in a laboratory plant with regard to the quality achieved in the semi-finished product. In addition, any hardware adaptations are to be designed and implemented in the test line. The aim is to control the composition of the material more precisely and to increase the productivity of the system.


The following tasks form the content of the work:

  1. Literature research on radar-absorbing materials (RAM), FRP production, FRP testing
  2. Familiarisation with the existing system with subsequent identification of core parameters in the process and their correlation to quality criteria in the semi-finished product
  3. Systematic optimisation of the system and validation of the results
  4. Discussion and documentation of the work results


What we offer:

  • Availability of the WIWeB's expertise in material analysis and access to many test procedures
  • Active involvement in the research team of the technical centre for radar camouflage materials
  • Practical final thesis with a high experimental component


What we expect:

  • Technical degree, e.g. aerospace engineering, mechanical engineering, or a comparable degree programme
  • High degree of initiative and ability to work in a team
  • Interest in experimental challenges and problems
  • Previous knowledge in the field of fibre-reinforced plastics desirable


The work is mainly carried out at the WIWeB site in Erding.
