FRP material has become a new type of structural material for its light weight, high strength, durability and corrosion resistance. At present, there are two main application ways of FRP materials in construction engineering.

1. Repair and reinforcement of structural materials

2. Replace steel bars or steel pipes and apply them directly to new structures.

Through calculation, in the engineering structure, the tensile strength of the same section is achieved, and the price of GFRP reinforcement is 0.52 of the prices of ordinary reinforcement. That is to say, using GFRP Bars instead of ordinary bars, only considering the tensile strength of materials or the section tensile strength achieved, the price of materials will be reduced by nearly half.
