Abstract
Induction welding has emerged as a promising technology for fusion bonding of carbon fibre reinforced thermoplastic composites. The process relies on the generation of eddy currents, induced by an alternating electromagnetic field, within a composite susceptor. The eddy current density and the resulting heat generation is directly influenced by the electrical conductivity of the carbon fibre
network, making accurate measurement of this orthotropic electrical property crucial for physics-based process simulations. The present study focuses on the characterisation of the in-plane transverse electrical conductivity in unidirectionally reinforced PAEK composites using the six-probe method. The
investigation specifically addresses the stochastic nature of the conductive paths within the fibre networks by considering the effects of the specimen dimensions and the uniformity of the current density field. The conductivity data obtained within this study is found to be consistent with earlier characterisation efforts that employed a different analysis technique. The agreement serves as a reliable validation of the methodology used in the previous study and provides valuable insights for future research in the field of electrical characterisation.
