Study on Effect of Heat Treatment on C/C-SiC Brake Performance

Abstract After powder metallurgy and carbon/carbon brake materials, carbon-ceramic material (C/C-SiC) is a new generation of braking material. There are currently some batches materials whose friction performance could be better: slightly higher than the standard. SiC was introduced into C/C-SiC disc through Polymer Impregnation Pyrolysis (PIP), composition friction-wear C/C-SiC-SiCp were investigated. The findings indicate that by PIP amorphous, existing in material’s pores, porosity reduced to 7%. With increase speed, curve demonstrates transition from inverted trapezoidal saddle-shaped. line wear rate 0.6 μm/cycle at medium high speeds compared with C/C-SiC.
