Damage characteristics of sandwich bulkhead under the impact of shock and high-velocity fragments

  • 摘要: 为探讨导弹战斗部近炸下舰船夹芯复合舱壁结构设计方法,采用TNT和预制破片近炸实验研究了典型夹芯复合舱壁结构在冲击波与高速破片联合作用下的破坏效应,分析了冲击波和破片联合毁伤载荷,指出了钢质面板和抗弹层的破坏模式,阐述了夹芯复合舱壁结构的防护机理。结果表明:预制破片装药近炸下,破片能远大于冲击波能,是防护结构的主要设计载荷;前面板主要是抵御冲击波,其变形破坏整体为挠曲大变形,局部为集团破片冲塞破口、破片穿孔和撞击凹坑;背板以挠曲大变形吸能为主;陶瓷材料碎裂严重,部分陶瓷碎片反向飞溅撞击前面板;纤维增强复合材料发生了纤维断裂、基体开裂、整体弯曲大变形及分层等破坏,抗弹层应避免产生穿透性破坏。
