Single Fiber Testing Study the Mechano-Electric Behavior between Carbon Fiber and Cement

Abstract:

Article Preview

The mechano-electric behavior between carbon fiber and cement matrix was revealed by single fiber testing. The resistance between fiber and matrix was found to increase when the interfacial bonding force increased and decrease when the interfacial bonding force decreased under dynamic load, which exhibited good reversibility except the first loading. The irreversibly increasing resistance is associated with interface debonding due to the interfacial defect, and the reversibly increasing resistance is attributed to elastic deformation of interfacial structure. The interfacial shear stresses cause the change of interfacial structure, which produce an effect on conductive network of the complex, and lead to the change of resistance between fiber and matrix.
