Abstract

In this work, a non-asbestos friction material was developed using an agrowaste material base which is palm kernel shell (PKS), along with other constituents. This was with a view to exploiting the characteristics of the PKS, which are largely deposited as waste from palm oil production, in replacing asbestos which has been found to be carcinogenic. Five sets of brake pads with identical ingredients which using PKS as a base materials were produced following the standard procedure employed by the manufacturers. The properties of the brake pads with different PKS and aluminum oxide composition were then evaluated and tested using American Society for Testing and Materials (ASTM) testing standard while the microstructure were analyzed using optical microscope. PKS was better than the asbestos-based brake-pad in terms of lower specific gravity; lower percentage swelling, when wet; higher heat resistance, heat dissipation and coefficient of friction. Therefore, PKS is suitable for use as a material for friction material in automotive brake pad. Further study would enhance the value of PKS as an alternative material replacing the asbestos as a friction materials.
