Fiberglass rebar production uses pultrusion molding process. It’s mainly longitudinal enhancement. Fiber content is 50% ~ 65%. In the past 10 years, fiberglass reinforced rebar has effectively replaced steel rebar in many projects, especially with the price advantage, its application is increasing.
Because the fiberglass reinforced rebar structure and corrosion resistance, which is especially suitable for underground engineering, offshore concrete structures and area. For some special building facilities, such as magnetic resonance imaging room in the hospital or by radio frequency technology to identify prepaid customers highway toll station channel, FRP rebar is the best choice. The FRP rebar has excellent electromagnetic wave permeability. In addition, the light weight property (approximately 1 / 4 of steel rebar) and adiabatic also makes it more and more popular.
Fiberglass reinforced rebar is generally made of E glass fiber and vinyl ester resin. There are also examples of the use of ECR glass fiber. In addition to vinyl ester, polyester, epoxy and phenolic resin also can be used for production.
