Carbon Fiber Rebars & Tapes




Pulwell CFRP rebars and tapes are made of high strength carbon fiber and epoxy resin, which can provide superior tensile strength, shear strength and modulus。




Pulwell CFRP rebars and tapes are typically used to strengthen  existing structural members (concrete, wood, stone or masonry) in flexural and shear. Structures, which are deficient due to either a structural flaw, deterioration or because of a change in use can often be brought to a useful capacity using Pulwell series CFRP rebars. 


Due to their extremely high strength and stiffness, along with the fact that theywill not rust or corrode and are very light weight, Pulwell CFRP rebars and tapes are often added to the concrete cover of  an  existing structure using a technique called “Near Surface Mount”  or NSM strengthening. The method is analogous to adding “band aid” rebar to the structure.


When combined with a proprietary factory applied anchorage, the CFRP rebars can be used as pre- stressing or un- bonded post tension tendons or earth anchors.  


Occasionally, the CFRP rebars are used as traditional concrete reinforcing bars, typically in restoration or repair situations.


Benefits of  Pulwell CFRP Rebars and Tape


• Impervious to Chloride Ion and chemical attack ~ Will NOT Corrode  
• Tensile strengths greater than steel 
• Modulus approaching that of steel & much greater than GFRP
• Can withstand greater sustained loads 
• 1/5th  the weight of steel rebar
• “Consumable” by excavating equipment
• Much higher bond strength with concrete than steel ,by external
helical wrap along with a sand coating of CFRP rebar, as well as
peel-ply rough surface of CFRP Tape
