本研究為延續實驗室過去半金屬摩擦材料所進行之研究，得知紅銅纖維/紅銅粉末的相對含量、半碳化溫度及石墨粉與雲母粉之添加之最佳製程參數－T3X1Y1試片具有適當的摩擦係數與低磨耗量，並且在噪音表現上較無噪音出現。
本研究以T3X1Y1試片為出發點且以摩擦時無噪音為前提，探討是否能在不使制動力減少太多的情況下，進一步改良T3X1Y1試片磨耗量較商業試片為多的問題。主要是以蛭石取代雲母作為摩擦調整劑，藉此探討此方式對半金屬摩擦材料在機械、磨潤等性質及在摩擦過程中噪音表現之影響，並進一步開發適合單車煞車使用之摩擦材料。
實驗結果顯示，添加蛭石之後試片摩擦係數顯著上升，但添加量過高時，反而造成摩擦係數起伏過大及磨耗量較高之現象，因此選擇適當的石墨與蛭石添加比例才能有助於自製試片磨耗性能之提升，勝過商業試片之表現，達到本研究之目的。

SUMMARY
This research is based on the past research of semi-metallic friction material, and we use copper fiber as reinforcement, copper powder, phenolic resin, and graphite powder as our material. In my research, I use vermiculite as the additives, and design three different series with different addition of graphite powder. In each series, I change the amount of vermiculite to investigate the influence to the properties of tribological and mechanical.
The results show that the coefficient of friction is increased as the addition of vermiculite rises up, but dramatically decreased when the addition of vermiculite keeps going up due to unstable friction surface and excess powder-like wear debris. Besides, there’s some noise being detected during the test procedure of specimens with higher amount of vermiculite. As for the weight loss, it is increased as the addition of vermiculite rises up. Therefore, I add more graphite powder as solid lubricants in order to compromise between the coefficient of friction and the weight loss.
In conclusion, specimen TGBVA has proper coefficient of friction, relatively low weight loss, noiseless while braking, and good mechanical properties. As a result, TGBVA is a better choice among all specimens.
