This paper studies the interface bonding performance of carbon-fabric-reinforced cementitious matrix (C-FRCM) composites with the impressed current cathodic protection (ICCP) technique. Single shear tests and pull-out tests on the C-FRCM composites are launched. Three current densities of 0, 100 and 150 mA/m² in the ICCP technique are considered. The resistance–slip relationships for all the composites are presented. It is found that the maximum resistance of the specimens in the pull-out tests decreases significantly with the increase of current density in the ICCP technique. Moreover, numerical analyses are conducted to obtain a simplified interface bonding stress–slip relationship of the specimens in the pull-out tests.

ICCP技术对碳纤维增强水泥基复合材料的界面行为

本文研究了外加电流阴极保护（ICCP）技术对碳纤维增强水泥基（C-FRCM）复合材料的界面结合性能。C-FRCM复合材料的单剪试验和拉拔试验启动。考虑了 ICCP 技术中 0、100和 150 mA/m ^{2的三种电流密度。}给出了所有复合材料的阻力-滑移关系。发现ICCP技术中，随着电流密度的增加，拉拔试验中试样的最大电阻显着降低。此外，进行数值分析以获得在拔出试验中试样的简化界面粘合应力-滑移关系。
