摘要
探究了不同碳纤维/玄武岩纤维(carbon fiber/basalt fiber,CF/BF)配比的混杂层合板在弹道冲击及冲击后压缩(compression after impact,CAI)性能方面的表现,结果表明,玄武岩纤维显著提升了混杂层合板的能量吸收能力。采用C扫描、电子显微镜和扫描电镜分析了材料的损伤机制,揭示了材料性能提升的内在机理。另一方面,混杂层合板的初始压缩强度随玄武岩纤维含量的增加而下降。在混杂层合板的能量吸收能力增强与初始压缩强度下降的共同作用下,CAI测试中受损层合板的残余压缩强度呈局部波动趋势。研究结果可为轻量化、高抗冲击复合材料的结构设计提供指导。
This study examines the ballistic and compression after impact(CAI)performance of carbon fiber/basalt fiber(CF/BF)hybrid laminates with different CF/BF ratios.C-scanning,electron microscopy,and scanning electron microscope were used to investigate the damage mechanisms,providing insights into the mechanism of the improved performance.The results show that the basalt fiber significantly enhances the energy absorption capacity of the hybrid laminates.Although the compression strength of the original hybrid laminates monotonically decreases with the increasing BF content ratio,the residual compression strength measured from CAI tests shows a locally wavy trend due to the competition between the increased energy absorption capacity and decreased original compression strength.This study offers guidance for designing lightweight,impact-resistant composite structures.
