Abstract

Friction characteristics of nine automotive brake friction materials containing different amounts of antimony trisulfide (Sb₂S₃) and zirconium silicate (ZrSiO₄) were investigated by using a brake dynamometer. Two different modes of brake applications (drag mode and stop mode) were employed to study the change of friction coefficient and torque variation (friction force oscillation). Results showed that the relative amount of Sb₂S₃ and ZrSiO₄ played important roles in determining the friction characteristics. Sb₂S₃ in the friction material improved the friction stability and ZrSiO₄ aggravated the torque variation during brake applications. (C) 2000 Elsevier Science S.A. All rights reserved.
