Carbon Fibre Fabric / Wrap

High strength carbon fibre fabric for external structural strenghthening

durafibre CFW is a high strength carbon fibre fabric, ready-to-use,incorporating durafibre CFW resin for impregnating, laminating the fabric by the wet lay-up technique. The carbon fibre laminate system offers outstanding tensile strength for bending loads, deformation, or increased stress and E-modulus for the structural strengthening of reinforced concrete elements.

    • Increase load requirements:

Increased traffic
Heavy machinery installed in buildings
External reinforcing flat structures like slabs and beams
Building/structure use change
Column confinement (bridges, parking garages and buildings)
Reinforcement of beams and slabs

    • Damage to structures through:

Corrosion of steel
Seismic activity
Durability reduction by fire

    • Durability:

Reduced stress in rebar
Prevention of further cracking
Suppression of crack width due to expansion
Reduce deformation
Satisfy design change requirements

    • Design or construction defects/changes:

Structures having insufficient reinforcing
Structures with insufficient element dimensions
New openings in structure to accommodate changes

  • Easy-to-apply
  • Carbon fibre offers exceptional tensile strengths and E-Modulus
  • Light weight, hardly no additional weight to the structure
  • Increase in bending moment
  • Increase in shear strength
  • Excellent static and dynamic fatigue properties
  • Composite system offer outstanding fatigue properties
  • Quick turn-around time for repair work
  • Corrosion resistant
  • Reliable structure repair system
  • Quality and performance is uniform due to pre-manufactured components
  • Can be overcoated

Surface Preparation

See durafibre CFW resin product data sheet.


See durafibre CFW resin product data sheet.

Cut the carbon fibre fabric to the required dimensions. The side and end laps are to be at least 100 mm respectively.

Note: Ensure adequate ventilation is available and prohibit open flames at the site. Protect from any wind pressure in tunnels or underground rail tracks that may cause the carbon fibre layup to detach from the concrete surface before curing.

Design Work

Consultation with a structural engineer is imperative when the design criteria and application configurations are required subject to load calculations of the various elements that are under consideration.


Protect outdoor applications from rain, dust and debris using a suitable plastic covering.

Allow the carbon plate adhesive to cure for 24 hours or more (increase the curing time when low ambient temperature is experienced).

Note: The use of any thinning solvent with the coating roller or brush is strictly prohibited. All relevant data sheets need to be read for additional information.


As per roll dimensions offered in the table above.

These calculations are theoretical and exclude waste or surface or element profile irregularities.

Protection on Completion

All applied product needs to be protected for at least 24 hours against the weather and high winds.


It is desirable to apply a polyurethane paint to the carbon fibre plate system for protection against ultra-violet rays and or subsequent environmental conditions. See “coating types”.

Painting should be performed in not less than 24 hours after the application of the carbon plate lay-up process.

Coating Types

UV protection – abecote® tough PU paint

 Damp/wet conditions – duraflex®, abe® silocoat

 Submerged conditions – duraflex®

 Chemical spill environments – abecote® SF 356 or SF 217

Model Specification

A high strength, carbon fibre fabric, incorporating an epoxy resin applied as a wet lay-up system to be used for structural strengthening.

The system shall be durafibre CFW high strength carbon fibre fabric including the impregnating durafibre CFW resin applied in accordance with the structural engineers detail and the recommendations of a.b.e.®


durafibre CFW is supplied in 100 m rolls.

500 mm wide x 100 m length (50 m2)
