摘要

本研究提出為了使軸承可以承受更大的負荷，且在某些應用上，可減少在整體軸承的尺寸。所以將溴化、陽極氧化與一般之碳纖維強化錫 - 鉛合金之複合材料。此複合材料經由擠壓鑄造而成。

碳纖維是由溴蒸氣進行溴化48小時，然後再放在200℃的空氣中12小時；另一項碳纖維陽極氧化，而是在稀氫氧化鈉電解質中3分鐘或者浸漬在硝酸72小時。

最後實驗結果發現，經過表面處理的碳纖維複合材料與沒經過表面處理碳纖維複合材料相較之下，經過表面處理之複合材料具有較高的拉伸強度和層間剪切強度，而含有溴化碳纖維的複合材料比其它兩種表面處理的具有更好的抗張強度。

In this project, in order to carry greater bearing loads and hence offer the possibility of reduction in overall bearing size for a given application.Use brominated, anodically oxidized, and pristine p-100 carbon fiber reinforced tin-lead alloy composites were fabricated by squeeze casting.

The fibers were brominated by bromine vapor for 48 hours and then desorbed at 200℃ in air for 12 hours. The anodic oxidation treatment of fibers involved electrochemical etching in a dilute sodium hydroxide electrolyte for 3 min, or immersing in nitric acid for 72 hours.

Finally, we accurately reproduce the composites containing surface-treated carbon fibers had higher tensile and interlaminar shear strength than the ones containing pristine carbon fibers. The composite containing brominated carbon fibers had better tensile strength than the other two surface treatments.
