COPPER-FREE CERAMIC FRICTION MATERIAL AND PREPARATION METHOD THEREOF

摘要

Copper-free ceramic friction material and preparation method thereof are disclosed. The friction material includes at least 2-30wt% alkaline earth metal compound and 2-30wt% carbon fiber, wherein said alkaline earth metal compound is MxFeyTiOz, wherein M is alkaline earth metal element selecting from Be, Mg, Ca, Sr or Ba, x is 0.2-2, y is 1-2, z is 4-16. The obtained friction material has excellent friction wear property, high thermal conductivity, excellent high temperature fade resistance, and can effectively reduce the temperature of the friction surface during braking.
