Multifunctional 2D-conducting nanostructured coating for aircraft components

Purpose and goal:

The main objective is to develop a multifunctional 2D-conducting nanostructured polymer coating for aircraft components,which is capable of surviving lightning strikes. This coating will combine electrical and thermal conduction capabilities. The end goal is to create efficient lighting strike protection for aircraft components made of carbon fiber reinforced polymers, effectively mitigating the impact of lightning strikes through enhanced electrical conductivity. The project focuses on improving the conducting properties of the graphenefunctionalized coating.

Expected results and effects:

By combining experimental activities, modeling, and simulation, the project seeks to achieve a groundbreaking coating system for aircraft safety.

The project results will be communicated through scientific publications, project internal reports, and workshops. Collaboration with the university in this research project strengthens the university’s competence in conductive surface coatings. This knowledge, together with published results, will be implemented

in student courses to further spread the knowledge. Approach and implementation:

Three work packages (WP-A, WP-B, and WP-C) are central to the project. WP-A (Chalmers-UFABC) aims to develop scalable technologies for producing conductive graphene-polymer nanocomposite coatings by optimizing their electrical and thermal conductivity. In WP-B (Chalmers), modeling and simulation are used to investigate the behavior of the LSP system under lightning strike conditions, optimizing the coating formulation and design parameters.

The WP-C (Saab) involves experimental testing at the coupon level and evaluation of the conducting properties
