英文摘要	In this paper the tungsten-fibre-net-reinforced tungsten composites were produced by spark plasma sintering (SPS) using fine W powders and commercial tungsten fibres. The relative density of the samples is above 95%. It was found that the recrystallization area in the fibres became bigger with increasing sintering temperature and pressure. The tungsten grains of fibres kept stable when sintered at 1350 degrees C/16 kN while grown up when sintered at 1800 degrees C/16 kN. The composite sintered at 1350 degrees C/16 kN have a Vickers-hardness of similar to 610 HV, about 2 times that of the 1800 degrees C/16 kN sintered one. Tensile tests imply that the temperature at which the composites (1350 degrees C/16 kN) begin to exhibit plastic deformation is about 200 degrees C-250 degrees C, which is 400 degrees C lower than that of SPSed pure W. The tensile fracture surfaces show that the increasing fracture ductility comes from pull-out, interface debonding and fracture of fibres.
