陶瓷/玻纤复合防护结构层间位置对抗破片侵彻性能的影响规律研究

为研究陶瓷/玻纤复合防护结构的层间位置对抗破片侵彻性能的影响规律,文中采用145 mm弹道枪加载方法进行了30 g破片对18 mm厚陶瓷(含有3 mm厚玻纤包裹层)/20 mm厚玻纤复合板的侵彻试验,并获得了破片的最小贯穿速度.同时,通过数值仿真进一步研究了复合板层间位置对抗破片侵彻性能的影响.结果表明,当靶板总厚度为38 mm左右,30 g破片以1 300 m/s的初始速度侵彻陶瓷/玻纤复合结构时,陶瓷板与玻纤板的厚度比在0.9.~1.7之间时其抗破片侵彻能力较好.

Research on the Influence of Ceramic/glass Fiber Composite Protective Structure Interlayer Position on Anti-penetration Performance

In order to research the influence ceramic/glass fiber composite structure interlayer position on fragment penetration performance, in this paper, the penetration test of 30 g fragment to 18 mm ceramic(Containing 3 mm thick glass fiber coating layer)/20 mm thick glass fiber composite structure was done using 14.5 mm ballistic gun load method and the minimum penetration rate of fragment was obtained.At the same time, the influence of composite plate location on the anti-penetration performance of fragment was studied by numerical simulation.The results showed that, while the tatal thickness of target panel was about 38 mm, and 30 g fragment penetrated ceramic/glass fiber composite structure with 1 300 m/s initial velocity, and the thickness ratio between the ceramic plate and the glass fiber board was between 0.9 and 1.7, the anti-penetration performance of fragment was better.
