Descripción del proyecto
Nuevos métodos para fabricar componentes de metal-polímero
Los materiales compuestos de fibra de carbono han ido reemplazando poco a poco a los metales en productos que necesitan ser ligeros. Sin embargo, el proceso de fabricación tradicional y la baja conductividad térmica de estos materiales ha limitado su uso a aplicaciones estructurales. Por ejemplo, las carcasas de baterías, los motores eléctricos y los dispositivos electrónicos de potencia suelen fabricarse íntegramente con aluminio porque requieren una disipación de calor eficiente. El uso de aluminio puro da como resultado una solución más pesada y menos rentable que el uso de materiales compuestos de fibra de carbono. La idea del proyecto MULTHEM, financiado con fondos europeos, es utilizar los diferentes beneficios de los metales y los materiales compuestos de fibra de carbono para desarrollar y validar nuevos procesos fiables de fabricación aditiva, así como nuevos multimateriales de metal-polímero con características estructurales y de refrigeración, con un enfoque más rentable que los métodos tradicionales.
Objetivo
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.
