中文摘要 | 為了維持機械強度,在製造過程中,光纖中的玻璃纖維會被鍍上塑膠材料。然而 、當外加拉力在玻璃纖維和第一鍍層間所引起之剪應力大於鍵結力時,則玻璃纖維和第一鍍 層之間的鍵結會被破壞且光纖會因此喪失其機械強度。在本文中,我們提出雙鍍層光纖中降 低拉力所引起塑膠被覆剝落的最佳設計。為了減少塑膠被覆層的剝茖,在玻璃纖維和第一鍍 層間因拉力所引起的剪應力必須降低。而降低此剪應力的方法是選擇合適的塑膠被覆材料如 下:第一鍍層的包松比和第二鍍層的厚度及楊氏模數必須增加,但第一鍍層的楊氏模數必須 減少;此外,第一鍍層的厚度具有一最佳值。 |
英文摘要 | To maintain the mechanical strength, the glass fiber of optical fibers is coated by polymeric matierials during the fabrication process. However, when the external tensile force induced shear stress at the interface of the glass fiber and primary coating is larger than its adhesive stress, the adhesive bond between the glass fiber and primary coating will be broken and the optical fiber will lose its mechanical strength. In this article, an optimal design of double-coated optical fibers to minimize the tensile force induced delamination of polymeric coatings is investigated. To minimize the coating's delamination, the tensile force induced shear stress at the interface of the glass fiber and primary coating should be reduced. The method to minimize such a shear stress is to select suitable polymeric coatings as follows. The Poisson's ratio of the primary coating and the thickness and Young's modulus of the secondary coating should be increased, but the Young's modulus of the primary coating should be decreased. On the other hand, the thickness of the primary coating exists and optimal value. |
