Abstract

Fiber-reinforced copper matrix composites are considered as a promising heat sink material for future divertor. In this article the structural reliability of a water-cooled tungsten mono-block divertor component with a composite cooling tube is treated. An integrated modeling scheme for multi-scale failure analysis is presented. The applied micromechanics-based FEM technique could be successfully combined with various failure analysis models to predict the failure risk on different length scales. It was demonstrated that the composite divertor component is a reasonable design concept in terms of structural reliability.
