综述了碳纤维增强水泥基复合材料(CFRC)电学特性的研究进展,探讨了CFRC的电磁屏蔽性能和导电性能研究中的相关问题,阐述了原材料、配合比和表面处理对CFRC电磁屏蔽性能的影响,明确了碳纤维分散性和试验方法对CFRC导电性能的影响规律以及CFRC在工程结构中的应用状况,展望了CFRC的发展方向,指出碳纤维分散性、测试方法、温度和应力等多因素条件是CFRC电学特性将来的研究重点.

The advances of electricity characteristics of carbon fiber reinforced cement based composites (CFRC) are presented. Some problems in study on electromagnetic shielding and conductivity are discussed. Inf-luences of raw materials, proportion and surface treatment on electromagnetic shielding effectiveness of CFRC are ana-lyzed. Influence rules of carbon fiber dispersion, test methods, etc on electrical conductivity and utilities of CFRC in engineering structure are pointed out. The developments of CFRC are viewed and the study keys of electricity charac-teristics, such as carbon fiber dispersion, test methods, multi factor conditions such as temperature and stress, and so on are put forward.
