Purpose The purpose of this paper is to investigate the friction coefficients of aramid and acrylic fibers on brake pads. Design/methodology/approach Fiber components used in the present pads are aramid and acrylic fibers respectively while keeping other components such as binders lubricants abrasives fillers the same. Disk FC25 and disk FC17 are used for rotor rubbing test to investigate the friction coefficients with brake pads. The pads are tested by 1/5 scale brake dynamometer and test mode is modified JASO C406-P1. The results are analyzed with the friction coefficient and the temperature transfer film roughness and photomicrograph of worn surface on rotors. Findings The friction coefficient was mainly determined by the pad material rather than the rotor material and pads made of aramid fiber had high-friction coefficient while pads made of acrylic fiber had low-friction coefficient especially under high temperature. Temperature change during braking process was directly related to the initial speed only and was indifferent to materials or decelerations imposed. In the fade test the reversal of friction coefficients between the aramid fiber and acrylic fiber pads is determined by the amount of remained amount of respective fiber above 520 C. Originality/value Effect of different fiber components aramid and acrylic fibers on friction characteristics of pad is sought. Reversal of friction coefficients is determined by the thermal stability of fibers used for pads. |
