Compared with single-layer CFRP, double-layer CFRP bears higher tensile stress, so it needs higher performance colloid to ensure the overall force.

Structural strengthening can not only improve the bearing capacity and durability of the structure, but also improve the seismic capacity. So can it be considered that conventional structural strengthening can simultaneously enhance the bearing capacity and seismic capacity, the two can be treated the same?

The tensile strength of the tow is very stable, the dispersion is small, and the coefficient of variation is below 5%. It is easy to control the performance and quality of the tow effectively in the process of production and use.

At present, it is very common to use carbon fiber reinforced polymer (CFRP) composite to reinforce bridges, especially when the structure is in corrosive environment, it is more suitable to use this kind of composite material to reinforce bridges.

Cut the precured FRP laminate according to the design size. When cutting, some carbon fiber laminate should be lengthened about 150 mm for normal tensile bond strength test, taking into account the need of field inspection.

If the area of a single empty drum is less than 10,000 mm2, it can be repaired by filling glue with borehole injection method; if the area of a single empty drum is more than 10,000 mm2, it should be removed and re-pasted steel plate with structural bonding adhesive, and re-checked and accepted.
