The Effect of Graphite and NBR on the Hardness of Fly-ash/Phenolic Composite for Brake Lining Application

摘要

Composite development is very intense to replace heavy and expensive metallic materials. One application of composite is a brake pad for vehicle. The composite for brake lining was consisted of various components which are divided into reinforcement, binder, friction modifier and filler. Composite in this study was made with variation in weight of graphite, NBR, fly-ash and phenolic resin. The hardness and abrasive tests were carried out to investigate the mechanical properties of the composite. Observation of the composite surface was carried out using SEM. The hardness and wear tests show that an appropriate composition of the phenolic and NBR was result in high hardness and low specific abrasion of fly-ash/phenolic composite.
