Modelling and Analysis of Disc Brake with Composite Material

The purpose of friction brakes is to decelerate a vehicle by transforming the kinetic energy of the vehicle to heat, via friction, and dissipating that heat to the surroundings. Automotive braking systems are normally made of steel or grey cast iron and are then paired with polymer-composite pads. These types of materials are suitable for use in braking systems with moderate loads with a limited temperature capability, where they exhibit a relatively high and stable friction coefcient, a low-wear rate and are quiet during operation. Composite brake discs are lighter, economical, and have excellent high energy friction characteristics. These have twice thermal capability compared to steel, remain unaffected by thermal shocks and mechanical fatigue. These are highly useful in emergency breaking situations. In this paper, carbon ceramic matrix disc brake material and steel material are used for calculating normal force, shear force and braking torque, and also to calculate the braking distance of the disc brake. The standard disc brake model is made using CATIA and the Static Structural analysis to calculate the deformation of the brake model is done using ANSYS. This aids to understand the action of force and friction force on the disc brakes new composite material, and helps to provide evidence so as to why the composite material is better than conventional materials.
