This paper presents a modeling analysis of transient thermoelastic behaviors occurring in carbon/carbon composite brake disks for an aircraft. A finite element code was developed which allowed an effective investigation of the transient thermoelastic analysis. Since the heat capacity of carbon/carbon composite is very large, the high temparature of the brake disk system was confined to only the narrow regions near friction surfaces. Therefore, carbon/carbon composite brake disk system has little dependency on the boundary conditions of the system. The composite brake disk system had the larger contact regions on friction surface than the isotropic metal brake disk system. In conclusions, carbon/carbon composite brake disks have excellent thermal characteristics as a brake friction material with the comparison of the isotropic metal brake disk system.
