中文摘要
本論文旨在預測複合材料中空圓柱薄管使用何種接頭黏合,可以產生較佳效能之結構。所使用之複合材料黏結板為石墨纖維/聚二醚酮 APC-2 十六層積層板,包含十字疊[0/90] 、類似均向疊[0/45/90/-45] 兩種疊序,並搭配梯接、斜接兩種不同形式之接頭。在數值解析方面,使用有限元素法的套裝軟體ANSYS 5.5.1來分析黏著層接頭所產生之應力分佈。

論文中所選用之梯接接頭有兩種幾何外觀,即垂直於薄管軸方向之黏著層高度h分別為2mm及5mm; 斜接接頭也有兩種幾何外觀,即黏著層和薄管軸方向之夾角α分別為30°及45°。中空圓柱薄管之邊界條件假設為一端固定,自由端施一固定扭力負荷,數值結果顯示,梯接h=5mm之類似均向疊[0/45/90/-45] 的接頭,整體結構產生之von Mises 應力最低,故可推測其可承受最大外力負荷並獲得最佳效能。論文中接頭之幾何形狀、尺寸以及積層板疊序方向,均會影響應力分佈。
Abstract
The purpose of this thesis is aimed to predict that what kind of adhesive bonded joint of composite tube the can obtain more efficient structure. APC-2 sixteen-layer laminates of AS-4/PEEK were used as adherends, including cross-ply [0/90]4S and quasi-isotropic [0/45/90/-45]2S laminates. And we use two different kinds of adhesive bonded joints, including stepped lap joint and scarf lap joint. On the aspect of numerical analysis, we employ finite element method incorporate with the software of ANSYS 5.5.1 to obtain the distribution of stress on adhesive bonded joint.

In this thesis, there are two kinds of geometrical shape on stepped lap joint. The bonded layer height h that is vertical to the axis of the composite tube is 2mm and 5mm. There are also two kinds of the geometrical shape on scarf lap joint. The angle α between the bonded layer and the axis of the composite tube is 30°and 45°.The boundary condition on one side of the composite tube is assumed to be fixed. The other side of the composite tube is due to torsion. According to the numerical result, the stepped lap joint with h=5mm and quasi-isotropic [0/45/90/-45] occurs minimum von Mises stress, and we predict this kind of joint can sustain the maximum external load and obtain better efficiency. In this thesis, the geometrical shape, size and the direction of laminates of the joint will effect the distribution of stress.
