Development and tribological studies of a novel metal‐ceramic hybrid brake disc

Ceramic matrix composite (CMC) friction materials show promising tribological properties. Typically, carbon ceramic brake discs consist of a C/SiC rotor which is joined to disc bell. Within this work, novel metal-ceramic hybrid disc, consisting segments are mounted by screws onto an aluminum carrier body, was designed and investigated. A prototype built tribologically tested with three different pad materials, LowMet reference, modified SF as well C/C. constant starting sliding velocity 20 m/s braking pressures 1, 2, 3 MPa were To simulate emergency conditions 10 consecutive applications carried out in close succession for each material pressure. The C/C showed the highest average coefficient followed material. However, wear rates orders magnitude higher compared
