利用碳纳米管(CNTs)对酚醛树脂(PF)/玄武岩纤维(CBF)复合材料进行改性。研究了CNTs含量对PF/CBF复合材料力学性能和烧蚀性能的影响。研究表明,CNTs的加入能明显提高复合材料的力学性能,当CNTs质量分数为1.5%时,复合材料的弯曲强度最大,较未加入CNTs的复合材料提高约39.5%;当CNTs质量分数为0.5%时,复合材料的压缩强度最大,较未加入CNTs的复合材料提高约23.4%。 Phenolic resin (PF) / basalt fiber (CBF) composites were modified by carbon nanotubes (CNTs). The effects of CNTs content on the mechanical properties and ablation properties of PF / CBF composites were investigated. The results show that the addition of CNTs can significantly improve the mechanical properties of the composites. When the CNTs content is 1.5%, the flexural strength of the composites is the highest, which is about 39.5% higher than that of the composites without CNTs. When the CNTs mass fraction is 0.5% , The compressive strength of the composites is the largest, about 23.4% higher than the composites without CNTs.
