本論文旨在透過拉伸及疲勞實驗探討在相同裂縫長度的單邊裂縫狀況下，鈦/碳纖維/聚醚醚酮/二氧化矽奈米複材積層板於不同裂縫角度及不同環境溫度下的機械性質與抗疲勞性質。
實驗中使用的奈米複材積層板是由外側各一層的鈦金屬板、中間一層以[0° /90° ]s堆疊之碳纖維/聚醚醚酮預浸布(APC-2)及各APC-2間之SiO2 奈米粉所構成之三明治結構。使材料結合前，鈦金屬板欲經過陽極處理使鈦金屬板生成氧化層，以增加與APC-2之黏著力，再將各材料堆疊並利用隔膜成形法進行熱壓過程使各材料結合，結合後切割成規定的大小，並委託工廠以線加工方式切割單邊裂縫，裂縫長度固定為3 mm，而裂縫之角度θ各別為0°、45°與60°，以製成論文中使用之奈米複材積層板。
而實驗中，利用製好不同裂縫角度的奈米複材積層板在環境溫度100°C 、125°C 及150°C 下進行拉伸試驗，藉由獲得的高溫拉伸數據與繪製出負載-位移關係圖以探討積層板的機械性質。並於三種環境溫度中進行疲勞實驗，採用拉伸-拉伸的正弦波型疲勞負載，頻率為5Hz、應力比為0.1的疲勞負載，藉得到之數據整理並繪製成疲勞負載-振次關係圖以探討積層板之抗疲勞特性。藉上述的實驗與整理以歸納出裂縫角度與環境溫度對於奈米複材積層板造成的影響。
整理所有拉伸與疲勞的結果後，可以歸納出以下結論：第一，裂縫角度越大，積層板的極限強度越大，也可承受較多的疲勞負載次數；第二，環境溫度越高，積層板的極限強度則越低，可承受的疲勞負載次數也較少；第三，積層板在相同的裂縫長度時，裂縫角度的影響高於環境溫度的影響；第四，奈米粉末雖可提升積層板的極限強度，但對於抗疲勞性方面則無明顯的提升。

The thesis aims to investigate the mechanical properties and fatigue characteristics of inclined single-edge-cracked Titanium/AS-4/PEEK/SiO2 nanocomposite laminates at elevated temperature.
The nanocomposite laminates used was a sandwich structure of cross-ply AS-4/PEEK (APC-2) with SiO2 nano-powder between the titanium sheets. Then they were cut into a predetermined dimensions. Each sample was cut a unilateral crack by wire processing at factory. The length of the crack was fixed at 3 mm, and the inclined angles θ were 0°, 45° and 60°.
In experiments, the tensile tests were carried out at various ambient temperatures of 100°C , 125°C , and 150°C . The fatigue tests were also performed at three ambient temperatures of 100°C , 125°C , and 150°C . The constant stress amplitude tension-tension cyclic tests were carried out by using load-control mode at sinusoidal loading wave with frequency of 5 Hz and the stress ratio of 0.1.
After finishing all tensile and fatigue tests, we obtain the results as the greater the angle of cracks, the greater the ultimate strength of the laminate, and can also withstand more resistance to fatigue load. Second, the higher the ambient temperature is, the lower the ultimate strength of laminates is, and the less the fatigue life is. Third, the effect of crack angle on strength and fatigue life is higher than that of ambient temperature. Fourth, the nano-powder can increase the ultimate strength of laminates, but doesn’t have significant improvement in fatigue resistance.
