本研究依循著達西定律來建立平板實驗的方法，首先透過實驗所得的數據求得纖維布的孔隙率及滲透率，並且逐一與Moldex3D進行模擬比對，發現我們所建立的實驗方法可行，而且比對後的準確度很高。接著我們將大型模具的模型放入Moldex3D中進行模擬，接著嘗試找出最適合的管路佈置位置，最終決定了最佳的管路佈置配置後，最後進行大型模具的實際灌注。
將大型模具灌注的模擬結果以及實驗結果比對後發現結果相差甚遠，在確認材料參數無誤的狀況下，我們針對製程上加以改善並且找出誤差產生的原因，進而發現到當入料管徑不夠大時會造成樹脂供應不及，造成誤差，因此我們加大了入料管徑後發現誤差縮小很多。

This study follows Darcy's law to establish the method of flat plate experiment. First, the porosity and permeability of the fiber cloth are obtained through the data obtained from the experiment, and the simulation comparison with Moldex3D is carried out one by one. It is found that the experimental method we established is feasible, and The accuracy after comparison is very high. Then we put the model of the large mold into Moldex3D for simulation, and then tried to find the most suitable piping arrangement position, and finally determined the best piping arrangement configuration, and finally carried out the actual pouring of the large mold.
After comparing the simulation results and experimental results of large-scale mold filling, it is found that the results are very different. After confirming that the material parameters are correct, we improve the process and find out the cause of the error, and then find that the diameter of the feeding pipe is not enough. When it is large, it will cause insufficient resin supply and cause errors. Therefore, after we increase the diameter of the feeding pipe, we find that the error is greatly reduced.
