Description du projet
Un nouvel horizon s’ouvre aux composants métal-polymère
Les composites fibres de carbone (CFC) remplacent de plus en plus les métaux dans les produits devant répondre à des exigences de légèreté. Toutefois, le processus de fabrication traditionnel et la mauvaise conductivité thermique des CFC à limité leur utilisation aux applications structurelles. Par exemple, les boîtiers de batterie, de moteurs électriques et de composants de l’électronique de puissance sont généralement entièrement faits d’aluminium, car ils doivent pouvoir dissiper efficacement la chaleur. L’utilisation d’aluminium pur engendre une solution plus lourde et moins rentable qu’une solution purement constituée de CFC. Le projet MULTHEM, financé par l’UE, a pour ambition d’exploiter les différents avantages des métaux et des matériaux CFC pour élaborer et valider de nouveaux processus fiables de fabrication additive et de nouveaux multi-matériaux métal-polymère dotés de caractéristiques structurelles et de refroidissement en adoptant une approche plus rentable que les méthodes traditionnelles.
Objectif
The 26th Climate Change Conference has highlighted the urgent need to reduce global carbon dioxide emissions to limit global warming. The transport sector accounts for approx. 16% of the global carbon emissions and has identified fleet electrification as the primary route to achieving climate neutrality. However, the main challenges are the current weight of components and the cost of new systems to ensure efficiency and long-term sustainability. As a result, the industry has recognised the need for transformative technologies and production methods to develop lighter, more efficient, and cost-effective solutions to enable this transition and achieve climate neutrality.
With their outstanding mechanical strength, Carbon Fibre Composites (CFC) have been increasingly used to replace metals in products requiring lightweight features, such as aircraft or high-performance vehicles. However, due to the traditional manufacturing process and poor thermal conductivity, the use of CFC has been limited to structural applications. For example, batteries, electrical motors, and power electronics, where power losses need to be efficiently dissipated, typically require separate heat exchangers, resulting in heavier and less cost-effective solutions that still utilize bulky designs and heavy materials.
The vision of MULTHEM is to develop a reliable and validated Additively Manufactured (AM) CFC process with enhanced thermal conductivity with different material combinations and nanotechnology. This innovative approach will allow the development of components, such as battery and motor housings with dual functionality comprising structural and cooling features and with a more cost-effective approach than traditional methods. This solution will enhance the product performance, first by the weight reduction achieved by designs that only AM enables, and second, by using CFC-metal structures with enhanced thermal conductivity strategies, lighter and stronger than aluminium or steel.
