Adaptability of Activated Carbon from Palm Oil Kernel Shell in the Brake Friction Materials

What is it about?

The objective of this study is to investigate the possibility of palm oil kernel shell (PKS carbon) to replace the commercial carbon in the fabrication of brake friction materials. Sample H and HB are composed of the same vol. % of ingredients, except that sample H was utilizing commercial carbon (C Carbon) while sample HB was utilizing activated carbon from PKS carbon as their carbon ingredient. Selecting sample HB as based formulation, vol. % of PKS carbon was decreased by 50 % (sample HA) and increased by 50 % (sample HC). The other ingredients in the compositions are proportionally decreased and increased, accordingly. The samples were examined for their porosity, hardness, COF and thickness loss.

Why is it important?

Ssample HB which composed of 20 vol. % of PKS recorded the highest COF and slightly higher thickness loss than sample composed of commercial carbon. Thus, it could be postulated that PKS carbon can be used to replace the commercial carbon in developing a new brake friction material with the best formulation containing 20 vol. % PKS.
