本實驗利用真空輔助樹脂轉注成形法配合電腦軟體模擬製作碳纖維複合材料飛機機翼結構肋。實驗中以不同織物層數碳纖維平板灌注來測量其滲透係數差異,並觀察樹脂在預成形物中流動、含浸之情形,及真空輔助時氣泡排除之狀況,配合電腦模擬樹脂在模穴中流動情況,再以所得之結果進行複材結構肋之製作。
由結果發現以真空輔助樹脂轉注成型製作機翼翼肋時,其產品性能及外觀都可以達到所要求的水準,且利用電腦模擬與傳統試誤法相比,可以有效節省過程所花費的時間,經測試後其平均層間剪切強度高於34.48 MPa,平均Tg點在180℃以上,平均Vf超過50%。
In this paper, the carbon fiber composites aircraft rib was fabricated with computational simulation by VARTM. The first step was to find the permeability of perform formed with different number of layers, and observed how the resin flow in the perform. The simulation result between two different setting of resin input gate were compared. The outcome of the simulation could provide the suggestions that about mold designing and VARTM process.
It is shown that no matter the outward appearance or the mechanical properties was satisfied. In this process, time could be saved much more than traditional method (try and error). The testing result present that the short beam shear strength was more than 34.48 MPa, the Tg is above 180 ℃, and the average Vf is 50%.
