摘要

本論文之研究結果可以使軸承承受更大的負荷，在實際應用上可減少軸承尺寸。碳纖維藉由鑄造來製造溴化、陽極氧化來做表面處理，此二種的和一般碳纖維以鎳和銅來塗覆，並以此纖維來強化錫-鉛合金複合材料。纖維由溴蒸氣溴化48小時，然後在200℃的空氣中12小時；另一纖維由陽極氧化處理，其方式為稀釋的氫氧化鈉溶液中以電化學蝕刻3分鐘。
經由實驗結果發現，含有塗覆處理的碳纖維複合材料比沒有塗覆處理的碳纖維複合材料具有較高的拉伸和剪切強度，此外，具有塗覆的溴化碳纖維複合材料比陽極氧化處理有更好的拉伸強度和剪切強度。
另外，挫曲分析的研究主要為探討一般金屬基複合材料和碳纖維、錫 - 鉛混合比例而成的細長中空圓柱0體，在受到一負載壓縮時所產生的變形結果做比較。

The results of this paper can make the bearing bear a bigger load,in practical applications can reduce the bearing size. Carbon fibers are made by casting to produce bromide and anodized for surface treatment. These two way and general carbon fibers are coated with nickel and copper,and the fibers are used to strengthen the tin-lead alloy composite. The fibers were brominated for 48 hours by bromine vapor and then desorbed at 200c in air for 12 hours；the other fibers involved electrochemical etching in a dilute sodium hydroxide electrolyte for 3 minutes.

The experimental results show that the composites containing coated treated carbon fibres had higher tensile and shear strength than the ones containing coated pristine carbon fibres.Moreover,the composite with coated brominated carbon fibres had better tensile strength and shear strength than the surface treatment.

In addition,the study of buckling analysis is mainly to explore the general metal-based composite materials and carbon fiber,tin-lead mixing ratio of the elongated hollow cylinder,the results of the deformation produced by a load compression are compared.
