摘要：

Tungsten fibers 150 mu m in diameter were formed into helices, whose helical radius and angle were 75 mu m and 78. 4 degree , respectively. They were embedded in a copper matrix by means of electrodeposition and vacuum hot-pressing techniques. The volume fraction of the fiber was 0. 72. When tensile tested, the helical fiber reinforced composites showed less notch-sensitivity than the straight fiber reinforced composites. A much larger plastic deformation zone was observed in front of the notch root for the former type of composite than for the latter type.
