What is CFRP Rebar?

Carbon fiber rebar (CFRP rebar): Carbon fiber rebar (CFRP rebar) is one kind of FRP rebar with carbon fiber as reinforcement. Taking advantage of the high strength and high modulus of carbon fiber, the obtained bar has the characteristics of high specific strength and specific modulus, and excellent mechanical properties, and is widely used in prestressed structures, such as prestressed beams, earthquake-proof houses, bridge cables, etc. Carbon fibres compared to AFRP’s can stand more heat and they do not absorb moisture. They have a very low thermal coefficient, which makes them desirable to be used in structures that are exposed to extreme temperatures. Carbon fibres are more attractive to be used in structural concrete reinforcement due to their high tensile strength and durability.

FRP (Fiberglass Reinforced Polymer) Rebar is a spiral wrapped structural reinforcing rod, it is one kind of composite material in market, Fiber reinforced composite is made of high performance fiber, synthetic resin (epoxy resin, vinyl resin, unsaturated polyester resin, etc.) matrix and curing agent. The fiber used are continuous fiber with high strength and high stiffness, FRP rebar can be used as an alternative to conventional steel reinforcement in structural concrete.

Fiber is reinforcement material and synthetic resin is matrix material. Fiber has high tensile strength, is the main provider of fiber reinforced composite strength, mainly play a load bearing role, mainly divided into carbon fiber, Arlene fiber, basalt fiber, glass fiber and so on. The matrix material has the function of bonding and transferring shear force, and its physical properties can affect the physical properties of fiber reinforced materials.The polymeric matrix binds the fibres and protects their surface from damage during handling, transporting, manufacturing, and the service life of the composite bars. In addition, the matrix plays an important role in the strength of the bars because it transfers the stress to the fibres through the matrix. Therefore it should be compatible with the fibres in terms of its thermal and chemical properties. The most common types of resin are epoxy, vinylesters and polyesters.

It has the characteristics of light weight, high strength, corrosion resistance, easy cutting and non-magnetic. It is widely used in subway tunnel (shield), expressway, bridge, airport, wharf, station, pavement, bridge deck paving, foundation pit construction, coastal engineering, tunnel new method construction, TBM construction.

Basalt fiber rebar (BFRP REBAR) is a KIND of FRP rebar reinforced with basalt fiber, Raw material is natural basalt made of green fiber, is an environmental protection product, its strength and modulus are better than ordinary glass fiber.

It is a relatively new material to the field of structural engineering. Using basalt fibres as reinforcement within a polymer matrix (FRP) has become more popular in the past decade. They have been used as reinforcement in concrete directly and as FRP for internal reinforcement as bars and external strengthening as sheets. They have excellent chemical resistance which are environmentally and ecologically harmless. Also they have no adverse reactions with water and are not flammable.

What is GFRP Rebar?

GFRP rebar is a plastic matrix composite material composed of organic non-metal (resin) and inorganic non-metal (inorganic fiber), which includes two parts: matrix and reinforcement. Through the pultrusion process, two kinds of composite materials with different forms and properties of fiber and resin are compounded together, and the composite material is formed by curing. Among them, resin is the matrix of GFRP bars, which is an organic non-metallic thermosetting plastic, which plays a bonding role, accounting for 65% to 75% of the total weight; continuous inorganic fibers are called reinforcements, which play a reinforcing role in composite materials. The main load-bearing component.
