摘　　要：采用热压烧结制备的碳化硼陶瓷和发泡法制备的泡沫铝,经环氧树脂黏结后制备得到碳化硼--泡沫铝双层复合材料.通过对材料靶板进行实弹靶试试验,着重研究和分析了该双层复合材料的防弹性能.靶试试验中,使用口径分别为7.62mm和12.7 mm的穿甲燃烧弹,冲击速度约820 m·s^-1,射击距离为10m.试验结果表明：碳化硼--泡沫铝双层复合材料对7.62mm口径穿甲燃烧弹具有较好的防护能力,其防护系数范围为5.06-5.12.Hot-pressed boron carbide and aluminum foams were connected by epoxy resin to prepare bilayer composite materials.The ballistic resistance of the composite materials was investigated by ballistic testing using the materials as target plates. Armor piercing projectiles,7. 62 and 12. 7 mm in caliber,respectively,were used as test projectiles. The impact velocity was probably of the order of 820 m·s^-1and the shooting distance was 10 m. It is found that the composite materials have good ballistic resistance to 7. 62 mm-caliber armor piercing projectiles,with the protecting factor in the range of 5. 06 to 5. 12.
