Selection And Optimization Of Kenaf/Epoxy Composite As An Alternative Friction Material

This research consists of the selection and optimization of the alternate materials which represent asbestos, using the Cambridge Engineering Selector (CES). The design and selection of potential materials are according to the friction material‟s suggested specifications and performances. Comparativ...
