Experimental characterisation of contact resistivity for CFRP wind turbine Spars9 equipotential bonding
Experimental characterisation of contact resistivity for CFRP wind turbine Spars9 equipotential bonding
This study aims to characterize the contact resistance of several equipotential bonding interfaces between the Carbon Fibre Reinforced Polymer (CFRP) spar and the Lightning Protection System (LPS). The total resistance of the coupons is measured, and the contact resistance is computed using the Finite Element Method (FEM). The latter is necessary to predict the resistance of CFRP components, which is not a trivial task because of the strong anisotropic nature of such materials. The developed methodology has been applied to a range of bonding materials: Expanded Copper Foil (ECF), Biaxial (Biax) CFRP and Unidirectional (UD) CFRP. It allows to propose the most reliable solutions for equipotential bonding applications.

Abstract
This study aims to characterize the contact resistance of several equipotential bonding interfaces between the Carbon Fibre Reinforced Polymer (CFRP) spar and the Lightning Protection System (LPS). The total resistance of the coupons is measured, and the contact resistance is computed using the Finite Element Method (FEM). The latter is necessary to predict the resistance of CFRP components, which is not a trivial task because of the strong anisotropic nature of such materials. The developed methodology has been applied to a range of bonding materials: Expanded Copper Foil (ECF), Biaxial (Biax) CFRP and Unidirectional (UD) CFRP. It allows to propose the most reliable solutions for equipotential bonding applications.
