FRP composite rebars 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 glass fibers 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. For improved stiffness and mechanical properties a carbon/vinyl ester product is available.
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.
Lightweight:weigh approximately one-quarter the weight of an equivalent size steel bar, offering significant savings in both placement and use.
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
High tensile strenghth:better than steel bar
High bond strength:better than steel bar in concrete
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:
Reinforced Concrete Exposed to Deicing Salts; Parking structures; bridge decks; Jersey barriers; parapets; curbs; retaining walls and foundations; roads and slabs on grade.
Structures Built in or Close to Sea water: Quays; retaining wall; piers; jetties; caissons; decks; piles; bulkheads; floating structures; canals; roads and buildings; offshore platforms; swimming pools and aquariums.
