Fiber Surface Treatment

Using orthogonal experimental design, the influence of water-to-cement ratio, silica fume content, and fiber surface treatment on the electrical and mechanical properties of carbon fiber reinforced cement was studied. Moreover, the surface appearance of fibers with and without surface treatment was investigated by means of scanning electron microscopy. The results show that the effect of water-to-cement ratio on conductivity is the largest among all the three factors. Fiber surface treatment plays an important role in the mechanical properties of CFRC and the optimum way is HNO3 treatment. By adopting the method of efficiency coefficient, the best combination can be determined effectively.

Fiber Surface Treatment

The effect of carbon fiber surface treatment on interfacial mechano-electric properties of carbon fiber reinforced concrete is studied by single fiber pull-out testing. As-received carbon fiber is with poor surface polarity, and the fiber-matrix interface bonding strength is low. Surface treatment of the carbon fiber improves both the interfacial bonding strength and the interfacial ductility. The interfacial bonding force and interfacial resistance increased linearly with increasing displacement until the fiber-matrix debonding was completed. The superior interfacial mechanical properties can help improve the strain-sensing ability relates to the better repeatability and reliability. But the sensitivity decreases to some extent.
