Abstract

The use of asbestos in friction material has been banned due to potential hazard to human. Nowadays, researchers have been striving to find sustainable and environmentally friendly materials for new friction material. This research is meant to study the effect of coconut fiber on mechanical and tribological properties of polypropylene (PP) as friction materials. A composite specimen from combination of coconut fiber and polypropylene (PP) is fabricated with different percentage composition ratio of materials and its effect to mechanical and tribological properties was investigated. The percentage composition ratio of material was found not affect the mechanical properties but slightly affect the tribological properties. This is due to the composition ratio of coconut fiber and polypropylene (PP) is commonly not mixing well during the fabrication process for the physical form of specimens. Then, for hardness properties indicated that this is due to the structure of the composite specimen which is contain lots of hole, void or empty space inside and for density properties indicated that this is due to its highest density which is also come from the fabrication process. Friction properties indicated that this is due to the facts that specimen A is the highest percentage contains of coconut fiber among the others with 25% coconut fiber constituent.
