摘要
研究钢、陶瓷和UHMWPE纤维3种材料板抗破片侵彻的最佳叠层方式.对同一结构圆柱形破片,采用弹道枪加载方式对钢、陶瓷和纤维为组元材料的5种等面密度复合结构进行等着速度侵彻试验,通过对比复合结构的贯穿情况,掌握组元材料的最佳组合模式为钢/UHMWPE纤维,并以极限面密度吸能为表征参量,进行了钢/UHMWPE纤维层合结构与Q235钢抗破片侵彻性能的对比试验.研究结果表明,钢/UHMWPE纤维层合结构的极限比吸收能是Q235钢板的3.55倍.
The optimal configuration sequence for the anti-fragment penetration performance of steel,ceramic and UHMWPE fiber laminates was studied in this paper.With the same impact velocity,penetration tests of ballistic gun-propelled cylindrical fragments to 5 kinds of composite structures with the same areal density had been carried out to seek the optimal configuration sequence.The comparison of penetration effect between 5 kinds of composite structures showed that steel/UHMWPE composite structure is superior in ballistic resistance.Then,the specific energy absorption was calculated to compare the anti-penetration capability of steel/UHMWPE composite structure with Q235 steel.The results showed that the specific energy absorption of steel/UHMWPE composite structure is 3.55 times as high as that of Q235 steel.
