Description

Fiberglass reinforced plastic (FRP) composite rebar (FRP rebar) are by combining the pultrusion process and an inline winding and coating process for the outside sand surface. The FRP composite rebar is made from high strength glassfibers along with an extremely durable vinyl ester resin. The glass fibers impart strength to the rod while the vinyl ester resin imparts excellent corrosion resistance properties in harsh chemical and alkaline environments. (Φ3mm-32mm)
FRP rebar significantly improves the longevity of civil engineering structures where corrosion is a major factor.


Features and Benefits:

Corrosion-resistance:will not rust, and are impervious to the action of salt ions, chemicals, and the alkalinity inherent in concrete.

High tensile strenghth:better than steel bar.(480-1000MPa).
lightweight:weigh approximately one-quarter the weight of an equivalent size steel bar, The density is 1.5-1.9(g/cm3).

High bond strength: thermal expansion coefficient is close to cement, better than steel bar in concrete.
electromagnetic neutrality:contain no metal, and will not interfere with the operation of sensitive electronic devices such as medical MRI units or electronic testing devices.
thermal insulator:highly efficient in resisting heat transfer, such as from building exteriors to interiors.

Excellent Fatigue Resistance:performs very well in cyclic loading situations


Application:

FRP composite rebar has cost effective application as a concrete reinforcing bar in the following markets when analyzed on a life-cycle cost basis:freeway;bridge;subway;tunnel;

railway station; airport; jetties; undergroud engineering; sewage treatment plant;chemical plant; electrolytic bath;manhole cover; reinforced concrete exposed to deicing salts; retaining walls and foundations; civil building; swimming pools; Applications subjected to other corrosion environment.
