This paper presents a inter-ply hybrid fiber sheet C/BFS (carbon/basalt fiber sheet) in order to solve the problems encountered in the application of FRP in the present strengthening engineering, such as inconvenient transportation, not ideal adhesive interface and low tension control stress. Interval impregnated inter-ply hybrid method was adopted to enhance the performance of C/BFS, not only increases the adaptability to the structure shape but also raises the utilization ratio of fiber strength. Mechanical tensile tests were conducted on interval impregnated C/BFS with different lengths (2m/5m/10m). Test results show that the prestress degree of C/BFS can be over 50% of its design stress after interval impregnation.
