구리 섬유의 종횡비 변화에 따른 마찰재의 마찰 및 마모특성

다국어 초록 (Multilingual Abstract)

The effect of the copper fiber length of the tribological properties of the brake friction material is investigated. Friction and wear of the friction materials are evaluated by a Krauss type tester using gray iron disks. Results shows that the friction material with short copper fibers (aspect ratio = 35) exhibits better friction stability at elevated temperatures than that with longer copper fibers (aspect ratio = 70), while the longer copper fibers shows higher brake effectiveness. On the other hand, the friction material with short copper fibers exhibits better wear resistance. Examination of the worn surface reveals that the formation of the nat area near the copper fibers appears to determine the level and stability of the friction coefficient. On the other hand, the wear resistance is affected by the thermal conductivity of the friction material, which is affected by the length of the copper fiber.
