Thermo-mechanical Model of Brake Composite Pads Reinforced with Nanotube Fiber to the Finite Element Method (FEM)

In this study, the temperature fields of composites ceramic pad modified with Nanotube carbon are investigated in simulations of real conditions for train brake pad. Temperature fields are simulated by using finite element method (FEM) of ABAQUS Software. Mechanical specifications of Nano-composite which is reinforced with random distribution Nanotubes obtain from Halpin-Tsai model. The simulation results are compared with experimental results to determine the effect of the matrix structure on temperature fields, which is helpful in designing the train braking systems and using the appropriate braking materials. Results verify the fact that Nano-composite pad in the train brake have lower maximum temperatures than other pads. Therefore, very long life is characteristic feature of this pad
