本研究使用酚醛樹脂、紅銅粉及紅銅纖維製作磨擦材料,藉由改變碳化溫度及銅粉與銅纖維的相對含量,探討纖維含量對銅/酚醛樹脂基半金屬磨擦材料機械及磨潤性質的影響。研究結果概述如下:
實驗結果發現, 機械性質方面,抗壓強度及硬度隨著銅纖維含量增加而下降。
磨潤性質方面,各類試片磨耗後的平均磨擦係數相距不大,約介於0.294與0.34之間,且碳化C2試片有最高的平均磨擦係數;各試片的磨擦溫度,隨著碳化溫度及銅纖維含量增加,各類試片磨擦溫度上升,且銅纖維含量影響較大。磨耗損失方面,隨著碳化溫度及銅纖維含量增加,磨耗損失降低。表面粗糙度方面,各類試片磨耗後的表面粗糙度會隨著碳化溫度及銅纖維含量增加而增加。
再現性磨耗測試,可觀察出各類試片磨擦係數與磨擦次數維持穩定,且隨著碳化溫度增加及銅纖維含量減少,各類試片平均磨擦係數有增加之趨勢。磨耗損失方面,隨著碳化溫度降低及銅纖維含量增加,磨耗量有增加之趨勢。
In this research, we used phenolic resin, copper powder, and copper fiber to manufacture friction material. By changing carbonization temperature and the relative content of copper powder and copper fiber, we understood the effects of carbonization temperature and copper fiber content on mechanical and tribological properties of copper/phenolic resin-based semi-metallic friction material. The results are as follows:
The results of mechanical properties of materials show that compressive strength and hardness decrease with increasing carbonization temperature and fiber conten.
Materials show little difference of average friction coefficient, about lying between 0.294 and 0.34, and carbonization C2 materials show the highest average friction coefficient. The friction temperature increases with increasing carbonization temperature and fiber content, but the fiber cotent shows large effective. Wear loss decrease when carbonization temperature and fiber content increases. Surface roughness increases with increasing carbonization temperature and fiber content.
In repeatable wear test,it shows that all specimens of average friction coefficient be stable. The average friction coefficient increases when carbonization temperature increases and fiber content decreases. Wear loss decreases when carbonization temperature increases and fiber content decreases.
