CFRP Carbon Rebar

CFRP carbon rebar (code  CRRTM) is one of the alternative materials for steel rebars that can maintain its durability well in corrosive environments with high magnetic degrees. Carbon reinforcement with sufficient strength can be well used in corrosive soil environments and as stabilizing materials for soil excavations. Having a very high tensile strength, makes the most use of CFRP carbon rebars in the use of retracted and active soil systems for well stabilization such as anchorage system.


Carbon Fiber Reinforced Polymer Rebar (code  CRRTM) is a high strength and low weight polymer which contains carbon fiber. Carbon fiber rebar can be used as a replacement for steel reinforcement in concrete structures such as parking structures, bridge decks, highways under extreme environments, and structures highly susceptible to corrosion and magnetic fields. As a result of its excellent properties, CFRP Rebar is used primarily in the construction industry to assist in building structures such as condominiums, office buildings, and shopping malls.

FRP carbon rebars are composite materials that are a combination of carbon fiber and heat-resistant polymer resin (epoxy hardener or polyester resin). The use of steel rebars in structures that are at risk of severe corrosion has been a major concern due to rust and concrete failure, and there are other solutions such as galvanized coatings, polymer-impregnated concretes and epoxy coatings. In the meantime, the use of FRP rebars, especially rebars made of carbon materials, has become more popular due to its mechanical strength and excellent curing. Object resistance and modulus of elasticity of carbon rebars are produced by various factors such as fiber volume percentage, type of epoxy resin or polyester resin, for fiber placement and carbon control during production. Common sizes for this type of FRP reinforcement are grade sizes 6, 8, 10, 12, 14 and even up to 25.

Frequently Asked Questions

What are the individual characteristics of carbon rebars?

Carbon rebars with very high tensile strength are mostly used in pre-stretched concrete systems and retaining walls to stabilize the pit such as the anchorage system. Carbon rebars also have good resistance to corrosion and chemical reactions.

What sizes of carbon rebars are available?

Common sizes for carbon rebars are grade sizes 6, 8, 10, 12, 14 and even up to 25.

What do you know about carbon rebars?

These types of rebars are rods made of carbon or composite resin that are prefabricated and have high strength and are used as internal or external reinforcement to create more strength and higher tensile warp.

How much is the tensile strength of carbon rebars?

The tensile strength is 2068MPa.
