本文采用羧甲基纤维素钠(Sodium Carbonxymethyl Cellulose,CMC)与硅微粉(Fine Silica Fumes,SF)作为复合分散剂对PAN基炭纤维进行协同分散来制备炭纤维增强水泥复合材料(Carbon Fiber Reinforced Cement Composites,CFRCC),研究了炭纤维用量、分散剂配比及水灰比对其强度的影响.试验结果表明,此法对纤维具有良好的分散效果.经过对各个掺量进行优选发现,在炭纤维为水泥掺量的1%,CMC和SF的分别为0.05%和15%,水灰比为0.30～0.32时效果最好,所得CFRCC7d(7天)的抗折和抗压强度分别提高了31.22%和41.25%.
