摘要

本文嘗試利用品質工程學之田口實驗計劃法探討防彈織物可控因子的影 響。使用田口方法之直交表設計進行實驗規劃'藉由子彈貫穿織物前後所消耗之能量測試其抗彈性能,以S/N比分析測試數據,暸解所選定防彈織物的 可控因子對抗彈性能之影響趨勢,再籍由ANOYA分析計算各可控因子之顯著性,進而選出最佳因子水準組合,並以驗證實驗確認為最佳化設計。結果顯示:子彈入射角度為60° , Kevlar29與Spectra Shield配置比例1 : 2 '排 列方式皆以0°/9°。連續排列之因子水準組合下,其有最佳抗彈性能,並擁有良好之再現性。另外得知子彈入射角度對抗彈性能之影響最為顯著,且發現子彈在低角度(30°以內)入射時,防彈織物之抗彈性能更劣於正面入射。

The thesis is tried to explore the influence on parameters of ballistic fabrics by Taguchi method. The orthogonal array of Taguchi method is used to organize the experiment and calculate the energy which was consuming by the ballistic fabrics, according to the distinct difference between the velocity before and after ballistic penetration. Then analyzing test data to understand the influence of ballistic resistance on control factors of ballistic fabrics with the signal to noise ratio. The percent contribution of each control factors is estimated by analysis of variance. And the optimal factor level combination is chosen, and the Optimization Design is verified by verification experiment to be the best.The result indicated也at the optimal factors of ballistic resistance fabric of shooting angle of bullet were 60° , cross-ply laminate both of Kevlar29, Spootra Shield and the ratio of Kevlar 29 and Spectra Shield were 1 :2, also has the best reproducibility. OtheIWise, the most influence of controllable factors is the shooting angle of bullet. We even found out that when bullet shooting at low angles, the ballistic resistance of fabric is worst than shooting of no angles.
