Abstract Cu-based powder metallurgy (PM) braking material containing iron powders with four kinds of particle size were fabricated， and the effect of iron powder particle size on the mechanical properties and brake friction performance was evaluated using universal testing machine and TM-1 inertial test stand. The initial brake speed is 50-380 km/h. Results show that the hardness of Cu-based friction materials decreases from 55.67 HRB to 31. 83 HRB and the shear strength decreases from 12.56 MPa to 10.27 MPa when particle size of iron powders increases from 20 μm to 70 μm. On the other hand， the samples with the largest iron particle size of 70 μm present the relatively high friction coefficient. The friction coefficient increases from 0.338 to 0.356 as the brake speed increases from 120 km/h to 380 km/h， and keeps at 0.355 when the brake speed is above 350 km/h. The properly high and stable friction coefficient is required for high speed train to brake urgently at high speed.

Key words： copper-based friction materials iron particle size brake friction friction coefficient
