摘　　要：碳纤维混凝土是在普通混凝土中均匀地加入短切碳纤维而构成的纤维增强水泥基复合材料,与普通混凝土相比,它不仅抗拉强度高、极限抗拉应变大,而且还具有温度和压力的自感知及电磁屏蔽等特性,是土木工程界新型的功能材料,在大型土木工程结构和基础设施的健康监测以及电子设备的电磁屏蔽等领域具有广泛的应用前景。Concrete with equably dispersed short carbon fibers is carbon fiber reinforced concrete (CFRC). In comparison with normal concrete, CFRC not only has higher tensile breaking strength and bigger maximum tensile strain, but also has the function of temperature and pressure sensing and electromagnetic radiation reflecting, and it has become a new functional material for civil engineering. CFRC has potential applications in the field of health monitoring of large civil engineering and basal establishment and electromagnetism shielding of electronic equipment.
