COPPER-FREE CERAMIC FRICTION MATERIAL AND PREPARATION METHOD THEREOF

摘要

The invention discloses a copper-free ceramic friction material and a preparation method thereof. The friction material at least contains the following materials in mass content: 2-30% of alkaline earth-based metal compound and 2-30% of carbon fiber, wherein the alkaline earth-based metal compound is M x Fe y TiO z , M is alkaline earth element Be, Mg, Ca, Sr or Ba, x is 0.2-2, y is 1-2, and z is 4-16. The friction material prepared according to the invention has excellent friction wear performance, high property of heat conductivity and excellent high temperature fading resistance. The temperature on the friction surfaces is effectively reduced during braking.
