本研究主要目的以熱壓製作聚氨酯(PU)、環氧樹脂(EPOXY)以及聚氨酯添加二氧化鈦(PU/TiO2)和聚氨酯添加石墨粉(PU/Graphite)之奈米高分子複合材料導輪(Wire guide roller) 披覆層應用於線鋸鋸切(Wire Sawing)製程，並對四款材質導輪其機械性質及導輪磨耗型態行為作探討，研究使用聚氨酯之主因是其具有良好力學性能和耐磨耗性能，期望再藉由添加填充物提升其強度及阻尼效果，另外在選用質地較硬之環氧樹脂和三款材質做比較。實驗上使用研究室所開發之小型複線式線鋸機進行四款導輪實驗，實驗後以光學顯微鏡(OM)觀察PU、EPOXY、PU/TiO2及PU/Graphite之導輪其溝槽磨耗變化差異，分別觀察溝槽幾何形狀變化、磨耗面積，來評斷其導輪耐磨耗程度之優異性，並對四款導輪所切下之晶片表面粗糙度趨勢進行探討。研究結果顯示PU/TiO2之導輪具有最佳之抗磨耗性，且切割之晶片品質僅次於PU/Graphite導輪，可提升線鋸加工之表現。

This study compares four different polymer materials as wire guides in wire sawing process. The four materials are EPOXY, Polyurethane (PU), PU reinforced by nano-TiO2, and PU reinforced by nano-Graphite. Polyurethane has good damping property and wear resistance. This is the reason why the industries wire guides. In order to enhance the performance of wire sawing, this study investigated wire sawing process with the guides made of these four materials. The wear of wire guides was observed by optical microscope and quantified by image process. In addition, the surface roughness silicon chip was measured. The results show the PU reinforced by nano-TiO2 was outperformed in wear resistance, although the surface roughness was slightly worse than PU reinforced by nano-Graphite. Therefore, PU/TiO2 has the potential to improve the performance of wire sawing process.
