考察了国产BF-CSH-01玄武岩纤维的耐酸碱性能,对其在80℃2 mol/L盐酸和氢氧化钠溶液中腐蚀不同周期后的质量变化、单丝强度、丝束拉伸性能及复合材料弯曲性能进行了实验研究,并与前期研究的国产BF-CMD-01玄武岩纤维的耐酸碱性进行了对比.结果表明,BF-CSH-01玄武岩纤维耐酸性能优于其耐碱性能,与BF-CMD-01纤维耐酸碱性相反.BF-CSH-01纤维酸碱腐蚀过程中的质量和强度下降规律存在较大差异:在酸性介质中,纤维强度及质量均缓慢降低,而在碱性介质中,纤维质量损失很少时强度即有大幅下降.BF-CSH-01丝束拉伸强度和复合材料弯曲强度受酸碱腐蚀影响较大,与单丝强度的变化规律一致,而模量下降较小.
