MODELISATION AVANCEE DE REVETEMENTS CONDUCTEURS POUR HELICOPTERES ET EOLIENNES

RAPID, DGA – DGE Project | Grant agreement ID: 182906097

December 2018 – December 2022

In the MARCHE project, highly electrically conductive coatings are elaborated to substitute metallic meshes used as lightning strike protection in aircraft. Indeed, these installations drastically penalize the reduction of weight earned with the replacement of titanium pieces by composites.

In the MARCHE project, highly electrically conductive coatings are elaborated to substitute metallic meshes used as lightning strike protection in aircraft. Indeed, these installations drastically penalize the reduction of weight earned with the replacement of titanium pieces by composites.

A thin ultra-conductive polyurethane-based coating is thus being developed by SPECIFIC POLYMERS and in collaboration with MAPAERO. The objective is to attain an extremely high level of conductivity (< 10 mΩ.sq) while maintaining the mechanical property and durability of the film in an aggressive environment.

In parallel, this project aims to assess the relevance of material modelling in the accelerated development of innovative high-performance resins. A thesis dedicated to this problem has thus been initiated by SPECIFIC POLYMERS within the SimatLab and the simulation of electrical conductivity in various polymeric matrices is being studied. This notion, involving a multi-scale methodology, has not been studied so far for such a property.

Thanks to the support of the material modelling and data sciences, very promising results have already been obtained with a competitive concentration of metallic particles (< 0.5 Ω.sq) . Further developments are on-going to concomitantly tune the mechanical properties and evaluate the efficiency of these coatings in lightning strike protection.

Multiple perspectives arise from the tools and know-how gained in this project for the elaboration of low resistive coatings whose electrical conductivity and mechanical properties can be adjusted depending on the application (flexible electronics, lithium battery, antistatic coatings, shielding, etc.).
