| Abstract: | The preparation technology for copper-based electrical contact materials reinforced by carbon nanotube was optimized by orthogonal experiment, and the effects of surface treating time, ball-milling time, and mass fraction of carbon nanotube on the comprehensive properties of this composite were studied. The results show that the optimal technological parameters were that the surface treating time of carbon nanotube is 1.0 h, ball-milling time is 8 h, and the mass fraction of carbon nanotube is 0.1%.
