Audited Supplier FRP( Short of Fiber Reinforced Plstic) is one kind of composite material made through the composite process with polymer resin as the matrix such as E-glass/basalt fiber or carbon fiber as the reinforcement. It has the advantage of high tensile strength, low weight, corrosion resistance and non-conductive than the steel rebars.
Glassfiber reinforced polymer rebar (GFRP) is made from high technical performance resin (UP/VE/EP/PU)and glass fiber by pultrusion process.
Compared with steel rebars, GFRP Fiberglass Rebar/Basalt Fiber Rebar have many advantages:
1. High tensile strength.
-Its strength is approximately double of steel bar, And when you bend it, it will bounces back quickly, that make the building more stable.
2. High corrosion resistance.
-Fiberglass rebar is waterproof and resistant to seawater corrosion, it never rust even stay in the concrete or building wall for many many years.
3. Low density and light weight.
-The meter weight is only 1/4 of steel bar, the worker can carry it easily, And also the transportation cost can be reduced much more.
4. Electrical insulation, without static electricity
-It has no electrical conductivity, and no sparks will be produced when being cut, it's particularly suitable for high risk gas zones; like Coal mines, oil fields.
5. Easy Cutting.
-Easy to cut, very suitable for construction of tunnels and subway projects, It avoids damages to cutter heads and does not delay excavation.
Applications:
Сonstruction,
subway tunnel,
coal mine tunnel,
rock surface anchoring,
sea wall,
parking structures,
slope support,
transportation industry and dam etc.
In marine engineering, reinforced concrete structures often cause steel corrosion, structural failure, and reorganization due to the intrusion of chloride ions. Because of its good performance, FRP tendons are considered to be the most effective material to replace steel in marine engineering.
we have studied the mechanical properties of GFRP bar material after corrosion in 60ºC and 40ºC water, acid, seawater, alkali, alkali+seawater and other five solutions through laboratory simulation. The results show that it has an impact
on the corrosion resistance of GFRP bar. The most serious is the alkali+seawater solution, but the tensile strength of GFRP tendons does not drop more than 30%, and the elastic modulus does not change more than 12%, showing good corrosion resistance. On this basis, the GFRP bar has been tested for its resistance to dry and wet cycles for 4 cycles. The test shows that the GFRP bar has good resistance to dry and wet cycles. The microscopic morphology of GFRP bars after corrosion was observed by SEM, and it was analyzed that the intrusion of moisture and OH- was an important factor that caused the decline of the mechanical properties of GFRP bars.
In order to simulate the actual environment of GFRP bars in the project, through self-made invention patents, the durability research of GFRP bars under the action of corrosive environment/stress was carried out, which filled the gaps in this research in China. The test results show that the tensile strength of GFRP bars has a small attenuation under this condition, and the tensile strength does not decrease by more than 11% under the 15% stress condition and the corrosive liquid for 1000h.
The test results meet the Canadian ISIS certification system's requirements for the durability of GFRP bar D1. Combining the Canadian ISIS system and the model proposed by Micelli in the United States, it is inferred that the service life of the GFRP bar exceeds 60 years. Based on the test data and the Arrhenius equation, curve
fitting and calculation are carried out, and it is predicted that the life of the GFRP bars selected for this project in the coastal area which will exceed 50 years, which can meet the actual needs of marine reclamation projects.
