Characterization of temperature rise of carbon ceramic brake disc

Abstract Carbon ceramic can be utilized in the manufacture of new brake discs for trains with high speed as a new composite material. In this article, temperature rises of C/C-SiC discs in emergency braking are simulated using conducting the front-head train model containing brake discs, and simulation results are analyzed with those of steel brake discs. With 400 km/h braking speed, the temperature peak of carbon ceramic disc can reach 1098.56 K at 86.3 s under braking conditions of emergency.
