機車用磨擦材料大體上分為二種:(1)有機磨擦材料以樹脂和石棉為主,(2)
半金屬磨擦材料以樹脂和鋼纖或鐵粉五為主.我的研究是以半金屬磨擦材
料為主,因石棉對人體有害所以已被人類禁用.研究是以不同成份和熱處理
來瞭解其對磨擦係數和磨耗量的影響,並且以SEM和光學顯微鏡來分析表面
磨耗前後的變化.

Automotive friction materials can be classified broadly into two
groups :(1)"organic"friction materials consisting of phenolic
resins reinforced with asbestos;and (2)"semi-metallic"friction
materials consisting of phenolic resinsreinforced with steel
fibers and iron powder.My research is about the "semi-metallic"
friction materials.Because the asbestos can affect our health,it
wasforbiden to use.From the different composition and heat
treatment,we can understand how the friction coefficient and
wear change with that.And from the SEM and optical microscope,we
realize the microstructure changes from nonworn surface to worn
surface.
