Wf/Cu82Al10Fe4Ni4(30) composites and Wf/Cu82Al10Fe4Ni4(60) composites were prepared by penetrating casting method. Three-point bending test and dynamic compression test showed that Wf/Cu82Al10Fe4Ni4(30) composites possessed higher mechanical properties than Wf/Cu82Al10Fe4Ni4(60) composites. Microstructure observation of Wf/Cu82Al10Fe4Ni4(30) composites revealed that a small amount of tungsten diffused into the Fe–Ni solid solution precipitated on the surface of tungsten fibers. The damage occurred mainly within the tungsten fibers after three-point bending test and dynamic compression test in Wf/Cu82Al10Fe4Ni4(30) composites, indicating that the composites possessed high interface strength. Dislocation density was high and stacking faults emerged in Wf/Cu82Al10Fe4Ni4(30) composites after dynamic compression. Microstructure observation of Wf/Cu82Al10Fe4Ni4(60) composites revealed that long strip of tungsten grains occurred at the edge of tungsten fibers, within which damage mainly emerged after three-point bending test, indicating that strength of the edge of tungsten fibers was low in Wf/Cu82Al10Fe4Ni4(60) composites. The fibrous structure of tungsten fiber was coarse or even disappeared in some areas, and dislocation density was low in Wf/Cu82Al10Fe4Ni4(60) composites after dynamic compression.
