Development of C/C–SiC Brake Pads for High‐Performance Elevators

Abstract

Novel C/C–SiC materials have been developed for their use as brake pads for high‐speed elevators. Under dynamic and stationary conditions, these materials exhibit high thermal shock resistance, high coefficients of friction, and extremely low wear rates. In addition, it has been found that the SiC content of the C/C–SiC materials on the friction surface heavily influences the frictional behavior. Low‐cost materials based on short fiber reinforcement and on drastically reduced process times showed their high potential for the manufacture of cost‐efficient brake pads.
