摘要: 碳纤维增强复合材料（carbon fiber-reinforced polymer，CFRP）具有优越的抗侵彻性能，正逐渐应用于舰船抗爆抗冲击防护设计。为了研究钢-CFRP层合板在聚能侵彻体作用下的防护性能，基于任意拉格朗日-欧拉方法建立聚能装药空中爆炸对钢-CFRP层合板破坏的数值模型，探究聚能装药的空中爆炸载荷特性及其对钢-CFRP层合板的毁伤机理。采用等面密度方法，设计了CFRP作为面板、背板和夹芯层时多种钢-CFRP层合板形式，通过侵彻后侵彻体头部降速以及层合板破口大小，讨论了CFRP敷设位置对层合板防护效果的影响，给出了较优的敷设形式。在此基础上，对层合板的厚度进行优化。结果表明：CFRP-钢-CFRP夹芯结构在聚能侵彻体作用下的防护效果最佳，较佳的厚度比为4.0∶1.4∶4.0。Abstract: Carbon fiber reinforced polymer (CFRP) is gradually applied to the design of anti-explosion and anti-shock engineering of warships due to its excellent anti-penetration performance. In order to study the protective performance of steel-CFRP laminates under the action of shaped charge projectile, numerical models of the damage analyses of steel-CFRP laminates under air explosion of shaped charge were established based on the arbitrary Lagrangian-Eulerian (ALE) method. The load characteristics and corresponding damage mechanism to steel-CFRP laminates were investigated. According to equal surface density method, various forms of steel-CFRP laminates with CFRP as face plate, back plate and sandwich core layer were designed. The anti-penetration performance of laminates with CFRP at different positions was compared and analyzed through the deceleration of the shaped charge projectile head and the size of the laminate crevasse, and a better laying form was obtained. On this basis, the thickness of the laminate was optimized. The results show that the three-layer sandwich structure of CFRP-steel-CFRP performs the best protective effect, and its better thickness ratio is 4.0∶1.4∶4.0.
