中文摘要 | 本文旨在報告使用光纖即時監控技術研究環氧樹脂模式系統之硬化反應,所用的 模式系統是化學計量比為1:1的縮水甘油苯醚(glycidyl phenyl ether)與二氨基二苯甲烷 (diaminodiphenyl methane)。研究重點在探討模式系統之折射率與硬化溫度和時間之關係以 及建立折射率增量(Δn)與反應程度(α)間之定量關係式。結果顯示,此模式系統之折射率受 物理(溫度)與化學(硬化反應)二項因素所控制,在110℃恆溫條件下前者發生在加熱的最初 10分鐘,後者則發生在10分鐘後至反應終止,有關此二項因素影響折射率之變化行為在本 文中有詳細之討論。關於折射率增量與反應程度間之定量關係式,則採用Albert與Malone 公式計算反應過程中環氧基濃度與反應程度之變化,並與折射率增量比較後,獲得一結論為 折射率增量與反應程度間存在著一線性關係為Δn=α/14.2,此關係式不受溫度之影響,因 此,可作為光纖即時監控環氧樹脂反應程度之依據。 |
英文摘要 | The goal of this study is to elucidate the relationship between the reaction time , extent of reaction, and the refractive index change of an epoxy model system during isothermal cure by an in-situ real time fiber optic cure monitoring technique. The model system chosen for this work consists of a stoichiometric amount of monofunctional epoxy, glycidyl phenyl ether, cured with a tetrafunctional amine, diaminodiphenyl methane. It was observed that the refractive index of the model system was controlled primarily by two factors, temperature and the cure reaction of the system. The effects of these two factors on the change behavior of refractive index have been discussed in detail in the text. The Albert- * Malone theory was applied to calculate the concentration of epoxy group and extent of reaction in this study. Comparison of the extent of reaction (α) with the increase of refractive index (Δ n) indicates that there is a linear relationship between these two parameters. According to the result, a linear equation of Δn = α I 14.2 can be obtained. It is noteworthy that the linear equation is independent of the cure temperature. This independence suggests the in-situ real time fiber optic monitoring technique can be a useful cure characterization method. |
