Abstract Scope |
In future D-T magnetic confinement fusion reactors divertor plasma-facing components (PFCs) will have to sustain intense particle, heat and neutron fluxes. In order that such components are capable of exhausting high heat fluxes during fusion operation reliably PFC heat sink materials with adequate properties as well as sufficient neutron irradiation resistance have to be applied. Currently favoured PFC heat sink materials, i.e. copper (Cu) alloys, suffer from a notable deterioration of mechanical and thermophysical properties under fusion neutron irradiation. A potentially advanced material against this background is a composite reinforced with tungsten (W) fibres that are embedded in a Cu (alloy) matrix. In the present contribution, recent progress regarding the fabrication and characterisation of such composites for PFC applications will be summarised. This will especially include results with respect to the textile processing of thin W filaments to fibrous preforms as well as results regarding corresponding composite material property characterisations. |
