本研究分為兩部分，第一部分為本實驗延續過去實驗成果使用製程放大的40 wt%剪切增稠流體浸漬於Kevlar 纖維中製備複合材料試片進行彈道測試。並以製程放大40 wt%剪切增稠流體經滾軋機製備成STF/Kevlar 複合材料，進行彈道測試(空氣槍)、落重刀插測試。由研究結果顯示放大製程流體浸漬於四層Kevlar K29 能達到和原製程一樣的防彈效果，加入STF 對子彈的能量吸收效果約提升11%；而兩層Kevlar K129 浸漬STF 效果更明顯，子彈能量消散提升約31%。以放大製程40 wt%剪切增稠流體和滾軋機所製成之4 層STF/Kevlar 複合材料經彈道測試(空氣槍)、抗刀插測試結果顯示彈道測試能達到與浸漬製程的防彈效果；抗刀插測試結果比浸漬製程來的更好。
第二部分為以製程放大40 wt%剪切增稠流體經滾軋製程製備20 層的STF/Kevlar 複合材料並製備成軟性鎧甲和30 層Kevlar 比較，進行彈道測試(實彈)、落塔刀插測試、撓曲度及厚度量測。結果顯示20 層的STF/Kevlar 複材和30層Kevlar 為同為NIJ 0101.04-II 防護等級，但20 層的STF/Kevlar 複材的厚度僅30 層Kevlar 的70%，20 層的樣品撓曲程度也較佳。落塔測試結果顯示以NIJ 0115.00 之S1 刀具衝擊靶材，20 層的STF/Kevlar 複材之抗刀插能力略優於30 層Kevlar。防彈性能的結果顯示兩者的防彈性能也相似，因此添加STF 可以讓複合材料變得更輕，更有可撓性，但不改變其防護性能。

This study reports a “scale up process” of shear thickening fluid (STF). The 40 wt% STF / Kevlar composite was manufactured by two different process. One is impregnating Kevlar fabrics with STF. The other method uses “mangle machine” padding the STF into Kevlar fabrics. The air gun impact test result of the impregnating method showed that STF impregnating with 2 layers Kevlar K129 can significantly increase EDP by 31%. The air gun impact test results of the “mangle machine” method prepared composite is similar with the sample prepared by the impregnating method. However, stab test results showed that sample prepared by the mangle method showed a better resistance than the sample prepared by the impregnating method.
The ballistic impact, drop tower, and flexibility tests were conducted. To determine the performance of 30 layers Kevlar without coating STF and the 20 layers STF/Kevlar coated with STF and made by the “mangle machine” method. The result of ballistic impact tests showed both 20 layers STF/Kevlar and 30 layers Kevlar were of the same protection level. They both meet the requirement of NIJ 0101.04-II protection standard. The thickness of 20 layers STF/Kevlar composites were 70% of 30 layers Kevlar. The flexibility tests showed that 20 layers STF/Kevlar composites possesses better flexibility than 30 layers Kevlar. The drop tower test indicated that the 20 layers STF/Kevlar showed similar protective effect as 30 layers Kevlar. The ballistic impact test also showed similar results. Adding STF made the composites lighter and more flexible than conventional Kevlar.
