Abstract

The brake system is the most important system in vehicle. While applying brake, thermal energy is produced from the kinetic energy. The main functions of brake drums are to slow down the speed of the vehicle, when the brake is applied. The brake drum material will be of heavy weight for the good performance. This work deals with the weight reduction in the brake drum material and also to achieve the high performance by using the composite materials. In order to achieve weight reduction in materials, the light-weight high performance components are increasingly using aluminium, magnesium, plastics and composites. Light weight and high strength component is made by Hybrid composite material. The use of Hybrid composite is becoming a viable solution to help the new system of the Automobile industry. In this Project, fabrication of metal matrix composite (AA6061+SiC+Gr) is done for automotive brake drum to attain weight reduction, corrosion resistance, thermal corrosion and also resisting temperature rise while applying brake force. The composition of the material is in different weight proportions, named as sample 1 and Sample 2. Frictional force is caused due to the sliding of two surfaces, which results in the heat energy from kinetic energy. After the fabrication of composite material for the brake drum, it was tested by using pin-on disc equipment for friction wear. The test result shows that the improved strength with light weight material and corrosion resistance is reduced in one of the sample.
