不同材料抗金属射流性能的试验研究

Experimental Study on Anti-metal-jet Performance of Different Materials

对陶瓷材料、树脂基纤维复合材料及混凝土复合材料进行了抗金属射流的探索性试验。结果表明 ,聚合物基复合材料在射流作用下产生塑性穿孔 ,其抗金属射流的性能优于普通陶瓷材料 ;材料的结构形式是影响其抗射流性能的重要因素 ,玻璃钢栅板比纯实心玻璃钢板对射流的衰减作用更为有效 ;材料厚度增加较大后 ,金属射流的侵彻性能将大幅度下降。

An explorative test has been made on anti metal jet properties of fiber polymer composites, ceramics and concrete composites. The test results indicate that the polymer composites have better anti metal jet performance in comparison with that of the common ceramics. The composition of materials is the main factor affecting the anti metal jet.The action of the metal jet creates plastic perforation for the polymer composites and brittle break for the common ceramics. The hollow grille plates of glass fiber reinforced plastics have better attenuation effect on metal jet than that of the solid plates, the penetrability of metal jet decreases greatly when sample’s thickness increases.
