Tungsten fibre-reinforced copper composites for high temperature and high heat flux applications

The present offer describes a tungsten fibre-reinforced copper (Wf-Cu) composite material concept that exploits the properties of commercially available drawn high-strength tungsten fibres embedded in a high conductivity copper matrix. With this approach, materials that can be realised exhibit outstanding property combinations regarding conductivity and strength. Such a composite material can hence be of interest in general regarding demanding high temperature and high heat flux applications. The development of Wf-Cu was being performed by fusion R&D institutions as potentially advanced heat sink materials for highly loaded, actively cooled plasma facing components.
