TRIBOLOGICAL PROPERTIES OF Canarium Schweinfurthii SHELLS AS FRICTIONAL MATERIAL AUTOMOTIVE BRAKE SYSTEM

Abstract

Friction material for automobile breaking system was developed using canarium schweinfurthii shell (CSS) otherwise known as African elemi. Tribological properties that direct or indirectly affect brake pad system such as thermal conductivity, water/oil absorption test, coefficient of friction, wear rate, hardness test, porosity, compressive, tensile strength, temperature, noise level generated and stopping time varying speed from 5.56 – 27.78 m/s was investigated. Experimentally developed produced brake pads using CSS were found to compete favourably with conventional brake pads and those from literature studies. The research finding using CSS indicates that CSS particle can effectively and efficiently replace asbestos in brake pad manufacturing.
