The purpose of the present work is to study and compare the physical, mechanical and tribological properties of hybrid fibers reinforced friction composites with steel fibre, rock wool fibre and glass fibre. The friction composites were fabricated by a compression molder equipment and tested using a constant-speed friction test machine. The experiment results show that recovery ratio of specimen FM9 (7.64 wt% glass fibres, 7.64 wt% rock wool fibres and 12.36 wt% steel fibres) was 89% and its fade ratio was only 28%, indicating the excellent properties of fade resistance and recovery. The friction coefficients of all specimens decreased with the increase of test temperature. Specimen FM7 containing 7.64 wt% glass fibres, 20 wt% rock wool fibres and 7.64 wt% steel fibres had the lowest wear rate (0.379 x 10(-7) cm(3)(N.m)(-1) at 350 degrees C), followed by specimens FM9 and FM5. The wear mechanism of the tested specimens was discussed based on the worn surfaces morphologies obtained using the Scanning Electron Microscopy (SEM). Specimens FM7 (Ra = 0.719 mu m) and FM9 (Ra = 0.731 mu m) show a relatively smooth surface in comparison to that of other specimens and have relatively smaller roughness, and they yielded the highest wear resistance performance.
