클러치용 Friction Bushing 마찰재의 미끄럼마찰특성에 관한 연구

다국어 초록 (Multilingual Abstract)

In order to investigate the wear properties of the friction bushing materials for clutch system of automobile. plate-on-disc type wear test have been conducted for three different types of composites reinforced by grass fiber. mineral fiber and mullite at several test conditions. In this paper. the friction properties of three different types of composites have been analyzed. Grass fiber reinforced composite exhibits lower friction coefficient, even though it maintains the friction coefficient stably under all test condition. It aseems to be due to the lubricity of grass fiber. On the contrary, the friction coefficient of mineral fiber reinforced composite exhibits unstable even though it shows high friction coefficient. The friction coefficient of mullite reinforced composite lies between these of grass fiber and mineral fiber reinforced composite. However deviation and amplitude of friction coefficient at a high temperature of 100℃ increases due to the formation of composite film transferred on counter surface.
