摘要
[目的]根据舰船轻量化的设计要求,纤维增强复合材料存在着抗冲击性能差等问题,需对其抗冲击性能进行研究.[方法]建立有限元模型,对一种适于海洋环境的玄武岩/钢混杂层板的抗侵彻性能进行研究,并验证其有效性.再对各工况下混杂层板的弹道性能和失效行为进行对比分析.[结果]多数情况下3/2铺层靶板的防护性能最好,复杂的铺层结构能够优化混杂层板的失效形式,使背板附近的铺层更倾向于呈现拉伸断裂的破坏形式.[结论]该破坏形式有利于纤维增强复合材料发挥其性能优势,提升防护效果.
Abstract
[Purposes]According to the lightweight design requirements of ships,fibre-reinforced com-posites have problems such as poor impact resistance,which need to be investigated.[Methods]In this paper,a basalt/steel hybrid laminate suitable for the sea is investigated for its anti-penetration perfor-mance.A finite element model is established and its validity is verified.Then the ballistic performance and failure behaviour of the hybrid laminates under various working conditions are studied compara-tively.[Findings]The results show that the 3/2-layered target plate has the best protection performance in most cases,and the complex layup structure can optimize the failure form of the hybrid laminate,so that the layup near the backing plate is more inclined to show the damage form of tensile fracture.[Con-clusions]This damage from is conducive to the fibre-reinforced composites to give play to their perfor-mance advantages and enhance the protective effect.
