      abstract     = {Demanding high heat flux applications, as for example
                      plasma-facing components of future nuclear fusion devices,
                      ask for the development of advanced materials. For such
                      components, copper alloys are currently regarded as heat
                      sink materials while monolithic tungsten is foreseen as
                      directly plasma-facing material. However, the combination of
                      these materials in one component is problematic since they
                      exhibit different thermomechanical characteristics and their
                      optimum operating temperatures do not overlap. In this
                      context, an improvement can be achieved by applying
                      composite materials that make use of drawn tungsten fibres
                      as reinforcement. For the manufacturing processes of these
                      composites, suitable tungsten fibre preform production
                      methods are needed. In the following, we will show that
                      tungsten fibres can be processed to suitable preforms by
                      means of well-established textile techniques as studies
                      regarding the production of planar weavings (wire distances
                      of 90–271 µm), circular braidings (multilayered
                      braidings with braiding angle of 60° and 12°) as well as
                      multifilamentary yarns (15 tungsten filaments with 16 µm
                      diameter) are presented. With such different textile
                      preforms tungsten fibre-reinforced tungsten (Wf/W) with a
                      density of over $99\%$ and pore-free tungsten
                      fibre-reinforced copper Wf/Cu composites were produced which
                      proves their applicability with respect to a composite
                      material production processes.},
