摘要：

The effects of the wool fiber as reinforcement in the friction materials on the friction and wear properties were investigated in this study. The contents of the wool fiber in the friction materials tested were 0, 3, and 4 wt%. The friction tests were conducted with a constant friction tester at a temperature range of 100, 150, 200, 250, 300, and 350 degrees C. The friction coefficient and wear rate were recorded. The friction coefficient of the friction materials reinforced with the wool fiber of 3 wt% was steady, and the wear rate was low. As the temperature increased, the stability of the friction coefficient of friction materials was improved. The Rockwell hardness decreased and the impact strength increased as the content of wool fibers was increased. The morphology of the worn surfaces was examined using scanning electron microscopy. The results indicated that the adhesive wear and abrasive wear were dominant in the friction materials reinforced with wool fiber.
