中文摘要 | 初步以擷取美國軍規之克維拉纖維板,製作30×30平方公分之大面積標準試片板材自行製作之疊層板,並作為槍擊試驗與分析破壞模式之主要依據。另對克維拉纖維板製作標準試桿之研究分析,發現其室溫之拉伸強度高達352Mpa,0.2% offset之降伏強度亦達347Mpa,最大拉伸長度達8.0%。經浸泡海水測試發現重量增加率隨時間之增長增加,並於浸泡2天後達於最高之吸水量,約為9.74%。耐溫試驗之結果,重量損失率最高達8.95%,其重量損失率隨溫度及浸泡時間之增加而呈現穩定之增減現象。衝擊值介於鋁合金與鑄鐵之間。 各類型結構材料之槍籍試驗已於聯勤205廠及國防大學中正理工學院完成初步驗証。計有Kevlar(克維拉纖維),GRP(玻璃強化塑膠)等測試板,以5.56mm及7.62mm穿甲彈實施槍擊試驗。經計算A積層板動能為1.67 KJ,B積層板動能為1.58 KJ,射入/出試板之動能差愈大,表示試板吸收子彈能量愈大,高性能複合材料皆可被穿甲彈貫穿,從槍擊試驗之結果顯示硬度愈高者,並不代表其抗彈性能愈佳。然後再以光學顯微鏡(OM)觀察,在不同環境測試,克維拉纖維之纖維束與基材間組織變化,並加以分析。 |
英文摘要 | The MIL-STD of the Kevlar Fiber board was manufactured from United States factory. 30×30 cm² plates were cut from the materials described above and in-house hand-made. The anti-ballistic tests and the descriptive models analysis could be identified as good patterns. Analyzing the Kevlar test pieces; the maximum tensile strength was up to 352 Mpa, with 0.2% offset Yield strength was 347 Mpa and the elongation rate was 8.0%. The immersion are rate of the test pieces into the clean sea water were increased as the time-lasted. But the maximum soaking amount about 9.74% was reached after 2-days later. The endurance of the temperature-rising test resulted the weitht loss to the maximum of 8.95%. The steady weight gains losses were followed with the temperature/soaking periods. The impact value was between the aluminum alloy and casting iron. Various structural composite materials were ballistic-tested at 205 factory and National Defense University at Chung-Cheng Institute of Technology. By using 5.56/7.62 mm piercing bullets, the dynamic energies of class A/B composites were 1.67 KJ and 1.58 KJ, separately. The more differences between the input and output dynamic energies, the more absorption of the composite materials. Although, the high performance composite materials were penetrated by the piercing bullets. The hardness of the test pieces could not the higher represent to anti-ballistic performance. The optical microscope observation were focused on the properties of the various composites. |
