以乙炔为碳源、二茂铁为催化剂,通过雾化辅助化学气相沉积法(AACVD)制备多尺度杂化材料CNT/CF.利用扫描电镜(SEM)、透射电镜(TEM)表征所制CNr/CF的形貌及其微观结构.结果表明:在反应温度750℃～800℃、沉积30min的条件下,碳纳米管(CNTs)能够以较高的密度均匀生长在炭纤维表面形成多尺度杂化材料CNr/CF.单纤维拉伸测试表明:在700℃～800℃、沉积30min的条件下所制CNT/CF的单纤维拉伸强度降低幅度小于13％；在反应温度750℃、沉积40 min的条件下、单纤维拉伸强度降低幅度小于10％.纤维悬挂液滴法研究表明:所制CNT/CF比原始炭纤维对环氧树脂有更好的浸润性能.
