COMPARATIVE THERMAL AND STRUCTURAL ANALYSIS OF AIRCRAFT BRAKE DISC MATERIALS

This paper presents a comparative study of
aircraft brake disc materials using thermal and
structural analysis. The materials considered
include Grey Cast Iron, Silicon Carbide (SiC)
reinforced composite, and Titanium alloy. A
three-dimensional model of the brake disc was
developed and analyzed using ANSYS software
by applying appropriate boundary conditions
such as heat flux and convection. The
performance of each material was evaluated
based on temperature distribution, stress, and
deformation characteristics. The results
indicate that Silicon Carbide composite
provides superior thermal resistance and
uniform heat distribution, whereas Titanium
alloy exhibits higher stress concentration due to
lower thermal conductivity. Grey Cast Iron
demonstrates balanced performance but is less
efficient compared to advanced materials. The
study highlights the importance of material
selection in improving braking efficiency, safety,
and durability in aircraft systems.
