Abstract: A process is provided for preparing a high-performance composite part that is electrically conductive at the surface. The process is used for improving the resistance of an electrically insulating part to rubbing, wear, and harsh atmospheric and/or chemical conditions, and to ensure the protection of an electrically insulating part against electromagnetic radiation (electromagnetic shielding) and/or against electrostatic discharges. The process improves the surface electrical conductivity of a material.
