摘要

本研究主要是採用玻璃纖維布以及環氧樹脂利用手積法製作出薄懸臂複合材料板，經過拉伸實驗測試，找出力量以及裂縫延展位移值，再經由這些數據計算出複合材料板的Model能量釋放率。而在ANSYS理論分析部分將板層分成三部份上下兩層爲板層，中間層爲膠層，板層採用SOLID191元素建模，膠層採用PLANE42元素建模讓ANSYS模擬出變形量，最後我們把實驗所計算的數據和ANSYS分析數據做比對，證實我們的ANSYS建模可以準確的模擬出實驗的數據，這樣一來就可以減少實驗的時間，直接以ANSYS建模就可以模擬出實驗數據。最後本研究還使用了玻璃纖維預浸材以及碳纖維預浸材兩種不同的材料做測試，實驗出數據來跟手積法的玻璃纖維作比較，並探討這三種材料對於該實驗的可行性。

The purpose of this study was to use glass fiber and epoxy resin to make thin cantilever composite plates by a hand lay-up technique. A tensile test was performed to identify and determine the extension force displacement values. The data obtained were used to derive the Model I energy release rate of the laminate plates. In the software program ANSYS, a SOLID191 model divided the plates into their composite laminates, the middle resin layer being a PLANE42 model, used to simulate the deformation. Finally, the experimental data obtained were used to confirm that our model can accurately perform simulations. Thus, this experiment enabled a reduction in the time required for direct ANSYS modeling in simulation. Furthermore, two different sheet materials, consisting of both glass and carbon fiber prepregs, were tested with the experimental data to design a hand-plot method for comparison and exploration of three materials to demonstrate the feasibility of the experiment.
