Wear Analysis of Graphene Nanoplatelets and Silicon Carbide Stir Casted Disc Brake Pad Assembly
Main Article Content
Abstract
This paper presents the wear analysis of brake pad and disc of an automobile using pin on disc experimental setup. The brake pad, consisting of silicon carbide and many other binding and filling materials, is stamped with the graphene nanoplatelets. The graphene nanoplatelets are mixed with the cast iron which is usually used as disc for braking assembly of an automobile. The pins for the experimental purpose were made from the regular commercial brake pad and stamped brake pad. The mixing of the graphene in the cast iron disc is done by the stir die casting method. The experiments were conducted to find out the wear volume, coefficient of wear rate and coefficient of friction. The wear parameters for the commercial brake pad assembly with and without graphene nanoplatelet are compared.
