Abstract

The effect of three different solid lubricants (graphite, Sb2S3, and MoS2) in the brake friction material on various aspects of friction characteristics was investigated. Three friction material specimens were produced based on an experimental formulation, and they contained 10 vol.% graphite, 7 vol.% graphite + 3 vol.% Sb2S3, and 7 vol.% graphite + 3 vol.% MoS2, respectively, fixing the composition of other ingredients. Tribological properties of the friction materials were obtained using a brake dynamometer. Results showed that the friction materials containing Sb2S3 and graphite improved friction stability and fade resistance. The friction materials with Sb2S3 and MoS2, on the other hand, exhibited disadvantages in terms of wear resistance, anti-fading, and DTV (disk thickness variation) generation.
