Abstract

L'invention concerne un élément comprenant au moins deux composants, au moins un composant étant un composant hybride dans le composite métal/matière synthétique, contenant au moins une tôle métallique de protection contre un rayonnement électromagnétique, des champs magnétiques dynamiques et statiques et/ou électriques dynamiques ou statiques, et au moins une couche de matière synthétique thermoplastique, thermodurcissable ou élastomère appliquée sur la tôle métallique par liaison de matière et/ou par complémentarité de formes. L'invention est caractérisée en ce qu'au moins un conducteur électrique est situé entre les au moins deux composants. L'invention concerne également un procédé de fabrication de cet élément et l'utilisation de cet élément dans les automobiles, l'électronique de puissance, la commande de moteur, les lignes de commande et de données, les dispositifs de commutation et de protection, les dispositifs de mesure, d'information et de signalisation, la technique de messagerie, la technique de communication, la technique de transmission, la technique de régulation, comme lignes de mesure, de contrôle et de commande, par exemple en génie mécanique ou en ingénierie des systèmes, en particulier comme ligne de connexion et de raccordement de machines-outils, lignes de production, unités de commande, tableaux de commande, dans la construction d'installations, les centrales électriques, le chauffage et la climatisation, les systèmes de refroidissement, les machines de bureau et les équipements de traitement de données, à chaque fois pour la protection contre le rayonnement électromagnétique, les champs magnétiques dynamiques ou statiques et/ou électriques dynamiques ou statiques, générés de préférence par l'au moins un conducteur électrique.
