摘要整理
将分级芳纶/氧化锆混杂纤维引入玄武岩纤维增强复合材料（BFRP）的层间区域，以优化其层间性能。通过三点弯曲试验和压缩试验，研究了微纳芳纶短纤维（MNASF）和氧化锆纤维（ZF）在不同质量比下对BFRP复合材料的增强效果。结果表明，当MNASF和ZF的掺入量均为2 wt.%时，BFRP复合材料的性能增强最显著。三点弯曲试验结果显示，与未增强的BFRP复合材料相比，弯曲强度和弯曲模量分别提高了119.2%和62.6%。压缩试验表明，该配方使压缩强度和压缩模量分别提高了257.7%和121.6%。扫描电子显微镜和光学显微镜观察表明，MNASF和ZF的引入有效降低了层间区域树脂富集区的体积分数，主要失效模式从层间脱层转变为剪切失效。总体而言，MNASF和ZF的引入有效结合了两种纤维的增强效应，显著改善了BFRP复合材料的力学性能。
