Influence of matrix carbon texture on the temperature field of carbon/carbon composites during braking

The friction, wear and thermal properties and temperature fields of three C/C composites with different matrix carbon textures were investigated in simulations of normal landing condition for aircraft brake disks. Temperature fields were also simulated using a finite element method. The matrix carbon textures had important influence on temperature fields. The sample with rough laminar pyrolytic carbon is the best choice for airplane brake disk due to its excellent friction, wear and thermal properties and lower temperature at the friction interface and thermal gradient by contrast with the samples with resin-derived carbon and smooth laminar pyrolytic carbon.
