A preparation method of carbon modified filler is provided. The method is: putting the fillers into the reaction zone of a reactor, starting the first heating-up to 400-500&#xb0; C. under the protective atmosphere at first, then introducing hydrogen after the heating-up; starting the second heating-up to 600-1200&#xb0; C. after introducing hydrogen and simultaneously introducing the mixture of hydrogen and carbon source gas, keeping at the terminal temperature for 0.1-5 hours, introducing nitrogen and stopping heating after the reaction, cooling, and then getting the carbon modified filler. The above method can obtain a friction material with good mechanical properties, excellent friction and wear performances, stable friction coefficient at high temperature, good braking force and no heat recession.
