Since the use of asbestos was banned in all types of products and applications due to its
carcinogenic nature, researchers worldwide has conducted extensive research and
development activities with the goal of identifying alternative and safe materials. This research work was conducted with the main objective of determining the potential and capability of using palm slag, an industrial solid waste that is abundant in Malaysia, as an alternative filler material in friction composites for brake pad applications. The
other main ingredient that were used to develop friction composites in this research
were, phenolic resin as a binder, graphite as a lubricant, alumina as an abrasive and
steel fibers to provide reinforcement. The mixture was hand press compacted to have
the 10 mm diameter cylindrical green body before being further compacted and cured
in a hot press at the 160 oC for five (5) minutes. Then the samples were post-cured in
the oven at 160 oC for four (4) hours before being tested for hardness, density,
compressive strength and resistance to wear. Characterization of the raw material,
especially the thermal behaviour of the palm slag, showed that it was thermally stable
and suitable for use as the filler material in brake pads. The processing parameters with
higher molding pressures had significant effects on the brake pad’s end properties, such
as density, hardness and compressive strength of the friction composite. The result of
this study also indicated that the mechanical properties of the composite material were
inversely related to the size of the palm slag particles that comprise the composite. The
