      abstract     = {To overcome the inherent brittleness of tungsten, which is
                      a promising candidate for a plasma-facing material in a
                      future fusion device, tungsten fibre-reinforced tungsten
                      composites (Wf/W) have been developed. As a part of the
                      materials characterisation program on Wf/W, we present the
                      results of first tensile tests of as-fabricated Wf/W in this
                      contribution. The results give insight on the ultimate
                      tensile strength properties and reveal the active toughening
                      mechanisms under tension load within the composite. Fibre
                      bridging, fibre necking as well as fibre pull out were
                      observed. This is leading to the typical pseudo ductile
                      behavior of the composite which is characterized by a rising
                      load bearing capability despite multiple matrix cracks
                      accompanied by non catastrophic crack propagation (in the
                      matrix). The description of the mechanical tests is
                      supplemented by detailed microstructural investigations.},
