摘要

本研究在實驗上使用點30穿甲彈對氧化鋁搭配Dyneema及Goldflex纖維組成之陶瓷複合材料進行抗彈性能評估，並以數值模擬分析，比照實驗結果建立模擬破壞的真實性，陶瓷與纖維具備不同的抗彈特性，陶瓷功能為磨耗投射體並降低其衝擊動能，纖維則是支撐陶瓷並以其拉伸強度吸收彈頭的殘餘動能，彈道測試結果顯示兩者纖維作為背板材料時吸收能量相近，但以變形量而論，Dyneema變形量大於Goldflex，且以Dyneema為背板材料時，陶瓷及纖維板有明顯的脫層現象。

The ballistic resistance capability of composite consisting of ceramics (Al_2O_3) with two kinds of fiber backplate (Goldflex & Dyneema) shot by 0.30 AP bullet was investigated in this project. Ballistic resistance mechanism of ceramics and fiber are different. The front plate of high-hardness ceramic is used to passivate the bullet and limit the bullet’s capacity to puncture in the first. Second, when the bullet hits the metal or high-tensile backing, the backing undergoes plastic deformation and absorbs the bullet’s residual energy. Results of ballistic test showed that the energy absorption of both specimens were similar. However, Dyneema deformed more than Goldflex and delaminated with ceramics.
