摘　　要：碳纤维增强水泥基复合材料因其优异的力学和物理化学特性而具有广泛的应用前景,但却面临纤维与水泥基体间界面性能薄弱的瓶颈问题。本文尝试将氧化石墨烯和石墨烯分别吸附在碳纤维表面,并用吸附后的碳纤维来增韧水泥基复合材料。研究发现,氧化石墨烯对碳纤维水泥基复合材料的界面性能和力学特性具有显著的增强作用,而石墨烯因其表面含氧官能团缺乏,则对其力学性能改善并不明显。Due to their excellent mechanical,physical and chemical properties,carbon fiber reinforced cement composites have great prospects in many fields,but face the bottleneck of weak interface performance between the fiber and the cement matrix.In this paper,graphene oxide and graphene are used to improve the interfacial properties of the composites.It is found that graphene oxide has remarkable reinforcing effects on the interfacial and mechanical properties of the composites.However,because of the lacking of oxygen groups in graphene,the improvement of the mechanical properties of graphene is extremely slight.
