Rotating brake discs with carbon laminated composite and e-glass epoxy material: a mathematical modeling

The main purpose of this study is to analyse thermomechanical behavior of a rotating brake disc. The importance of the brake system in vehicles is quite high. The brake disc is very important for the safety of a vehicle. A brake disc, an iron disc held by brake pads, is generally attached to the suspension of a car and it is located on a brake caliper. In vehicles, when the brake pedal is pressed, it slows down the rotation of wheels in the vehicle through friction. The heat generated during friction causes negative effects on the brake assembly. The discs under consideration consist of carbon laminates and E-glass epoxy materials. The obtained stresses are compared with each other. The tangential stress increases proportionally as the temperature increases. The brake system is the most important part of an automobile. The brake rotors of disc brakes rotate with the wheels, and brake pads attached to the brake calipers engage with these rotors to stop or slow down the wheels. They convert the kinetic energy of vehicles into heat, vibration and sound energy so that the vehicle can be stopped. This energy conversion takes place between the brake pads and the rotors or disc in a disc brake system. The heat of friction will reduce the coefficiency of friction, combining the effects of stress and temperature distribution. The analytical solution and those obtained by the Ansys finite element method are in alignment with each other and with other studies in the literature. Graphical abstract
