Abstract
The main purpose of this study is the optimization of disc brake materials by changing the radius
and the thickness of the disc using different materials to choose the optimum disc brake material.
The modelling of disc brake is made in CATIA software, the thermal and structure analysis is
done using ANSYS workbench. In this research, a transient thermal and structural analysis was
carried out to investigate the temperature variation across the disc and the total heat flux using
ANSYS software. The thermal-structural analysis is then used to determine the deformation
established and stresses in the disc. In all cases when the dimensions of disc model increase
temperature, deformation and equivalent stress decrease. For example the deformation of cast
iron decreases 7.0616e-5m to 5.4009e-5m when we change the model.
For the side of the material by varying the properties of the materials, the better material for this
study is the aluminium alloys 7075 with silicon carbide SiC/AL7075 because it has the minimum
deformation 3.6367e-5 for model3. Finally this thesis suggests the SiC/AL7075 to be used disc
brake material for the future with the model3.
