Nachhaltige Produktion – Emissionen vermeiden, Ressourcen schonen

H.P. Degischer; Thomas Albert Fechter

Nachhaltigkeit im weiteren Sinne ist ein Handlungsprinzip zur Nutzung naturlicher Ressourcen, bei dem das jeweilige System dauerhaft bewahrt wird. Dabei werden die Stabilitat und die naturliche Regenerationsfahigkeit der Ressourcen genutzt und erhalten.

3D Characterization of Thermal Fatigue Damage in Monofilament Reinforced Copper for Heat Sink Applications in Fusion Reactor Systems

M. Schöbel; H.P. Degischer; A. Brendel; B. Harrer; M. Di Michiel

Abstract Monofilament reinforced metals (MFRM) are developed as high temperature heat sink materials for fusion reactor applications. These composites combine the high thermal conductivity (TC) of a Cu matrix with low thermal expansion (CTE) of SiC or W filaments. The CTE mismatch between matrix and reinforcement lead to high micro stresses under operation conditions. Stress induced thermal fatigue damage such as interface delamination and fiber/matrix damage degrades the thermal properties of these composites. Different interface designs are developed for SiC as well as W filaments to improve bonding strength and increase the long term stability. Conventional as well as synchrotron tomography was applied on different MFRMs to characterize thermal fatigue damage and its propagation before, during and after thermal cycling.
