B03 Electromagnetic alignment of reinforcement elements
Summary
The DediGrad subproject B03 investigates the electromagnetic alignment of coated reinforcement fibres in order to tailor graded micro- and mesostructures in polymeric materials. For this purpose, magnetically functionalised carbon fibres are developed, suitable coating processes are designed, and the effect of external magnetic fields on fibre orientation, distribution, and embedding is analysed. The subproject combines electrochemical process development, material characterisation, compounding studies, and numerical modelling. Its aim is to establish the scientific basis for load-adapted fibre distribution in short- and long-fibre-reinforced thermoplastics as well as in transition zones towards continuously reinforced or non-reinforced substructures.
001 Objectives

Electromagnetic Fibre Alignment

  • Development of magnetically coated carbon fibres with suitable mechanical and magnetic properties
  • Design of the corresponding electrochemical coating processes
  • Investigation of the effects of magnetic excitation on fibre orientation in polymer matrices
  • Derivation of process limits and design guidelines for magnetic alignment
002 Scientific Questions

Field–Controlled Material Structures

  • How can suitable electroplating processes be established for uniform fibre coatings with adjustable magnetic properties?
  • How do electrolyte composition and coating parameters influence the microstructure and adhesion of the deposited layers?
  • Which governing mechanisms determine the alignment of magnetically functionalised fibres in thermoplastic matrices?
  • How does the compounding process influence the morphology and mechanical behaviour of the fibre and the compound?
