Abstract : It is shown that copper, reinforced with tungsten fiber to a volume fraction of 10 percent and more, possesses high resistance to fatigue breakdown at room temperature; with a volume fraction of fiber equal to 37 percent the fatigue limit rose from 8 to 32 kgf/sq cm. The high resistance of the composite to fatigue breakdown is caused by an increase in the energies of formation and propagation of cracks in metals and alloys reinforced with high-strength fibers.
