摘要： 研究了Si3N4/BN层状复合陶瓷的抗冲击破坏及抗穿甲破坏行为. 研究发现: 在射钉枪的作用下, 处于自由状态的Si3N4/BN层状复合陶瓷比Si3N4块体陶瓷具有更好的抗
冲击破坏能力. 在7.62mm口径穿甲燃烧弹的作用下, Si3N4/BN层状复合陶瓷的抗穿透能力比Si3N4块体陶瓷略有下降, 但仍远远高于45号钢材, 而且在实弹冲击后不会像Si3N4
块体陶瓷那样整体破坏.

Abstract: The behaviors of impact resistance and armour pierced-resistance of Si3N4/BN laminated ceramics were studied. The study on the impact resistance indicated that the impact resistance ability of Si3N4/BN
laminated ceramics was more predominate than that of Si3N4 monolith ceramics. The ballistic efficiency factor of the Si3N4/BN laminated ceramics was slightly smaller than that of the monolithic
Si3N4 ceramics, but it was much higher than that of steel. Compared to the smashing behavior of the monolithic Si3N4 ceramics, Si3N4/BN laminated ceramics could keep the integrality
to some extent after impacted by bullet. The destructive mechanism of Si3N4/BN laminated ceramics impacted by bullet was discussed, which provides theoretical analysis basis for its’ bullet-proof structure designing.

Key words: laminated ceramics, armour pierced-resistance, ballistic efficiency factor
