摘要：以碳纤维为增强相制备分散均匀的碳纤维增强水泥基（CFRC）复合材料，研究了碳纤维长度、掺量和成型工艺对CFRC复合材料性能的影响。结果表明：掺入碳纤维后，CFRC复合材料的力学性能有所提高，电阻率明显降低；采用10 mm碳纤维、掺量为0.6%时，CFRC复合材料的抗压强度最大提高了22.6%；碳纤维掺量相同时，碳纤维越长，电阻率越小；采用振动压实法成型试件，更有利于提高CFRC复合材料的导电率。

Abstract：Carbon fiber reinforced cement（CFRC） composites were prepared with carbon fiber as reinforcing phase. The effects of carbon fiber length，content and molding process on the properties of CFRC composites were studied. The results show that compared with ordinary cement，the mechanical properties of carbon fiber reinforced cementitious composites are improved and the resistivity decreases obviously. In CFRC composites，when 10 mm carbon fiber is used by 0.6%，the compressive strength of CFRC composites is increased by 22.6%. When the carbon fiber content is the same，the longer the carbon fiber，the smaller the resistivity is. And the test specimen molded by vibration compaction method can improve the conductivity of CFRC composites.
