Abstract

Aircraft brakes are very critical for its safe operation. During landing, the brakes takes 40% of the energy while aerodynamic brakes, reverses thrust and rolling friction takes the rest of energy, [1]. Thus superior tribological behavior at high temperatures is required to carry out this mission. Carbon fiber reinforced Carbon(C/C) composites have outstanding low density and high thermomecanical properties, [2]. For these reasons, more aircraft manufacturers convert to C/C brakes. The tribological behavior of C/C composites is examined in this paper by exploring the parameters that affect weight loss. The Taguchi method is used to conduct a design of experiment (DOE) to optimize the experiments size. The response surface methodology is utilized to ascertain the most favorable blend of process operating parameters. The Carbon/Carbon composite's wear and friction characteristics were evaluated using a dry sliding wear test, employing the disc-on-disc method. The findings revealed that the duration of contact between the stator and rotor discs was the most significant contributor to weight loss, followed by the applied load and rotational speed. The most predominant factor was the braking pressure then the time and vehicle speed.
