High-performance carbon fibre plate reinforcement for structural strengthening

Product Features

About this Product

webertec force carbon plate is high-performance, corrosion-resistant carbon fibre laminate. Manufactured by S&P, Switzerland, these laminates have a fibre volumetric content up to 70% in an epoxy resin matrix. When used with webertec EP structural adhesive, the laminates form part of the webertec force composite strengthening system. For use in accordance with Concrete Society Technical Report 55 Design Guidance for Strengthening Concrete Structures.

Features and Benefits

  • Can be used in conjunction with the webertec force CD design software package
  • Precise performance with high strength and high modulus of elasticity in quality controlled manufacture
  • Various strengths and modulus available for selection
  • No corrosion, excellent durability and minimal maintenance
  • Lightweight and easy to apply
  • Range of dimensions for designer to choose from
  • Available in any length
  • Factory lamination with 70% carbon fibre content
  • Good fire resistance of CFRP
  • High fatigue strength of unidirectional laminate
  • Excellent creep strength of CFRP over other fibre composites
  • S&P can manufacture any special width for specific projects

Preparation & Application

Preparation

Tensile forces are transferred from the carbon fibre plate through the adhesive into the bearing substrate. The substrate should therefore have an inherent surface tensile strength greater than 1.5 N/mm2. Testing of the tensile strength fctm of the substrate should be carried out prior to application of carbon fibre plate by a bond test.

The surface of the substrate must be roughened by grinding or sandblasting to remove any weak surface laitance or deleterious friable material. In order to prevent peeling due to deviation forces, the evenness of the prepared surface must be tested with a 2 m straight edge. Maximum allowable deviation is 5 mm over a 2 m length.

If the substrate is uneven, then it will need to be re-profiled using webertec EP highbuild or webertec EP structural adhesive. If the substrate is poor and the tensile bond strength is less than 1.5 N/mm2, the surface may need to be primed. Please contact Technical Services for recommendations.

Immediately prior to the application of webertec EP structural adhesive, solventwipe the carbon fibre plate with webertec solvent 1 to remove carbon dust and any contaminants. Wait until surface is dry before applying adhesive.

Application

Apply mixed webertec EP structural adhesive to the prepared concrete at 2 mm thickness and carbon fibre plate at 2 - 3 mm thickness within the pot life of the adhesive.

Place the carbon fibre plate onto the prepared substrate with the two adhesive layers in contact. Use a hard rubber roller to press the laminate onto the substrate until adhesive squeezes out from both sides of the laminate. Roller along the centre of the plate to achieve a void-free bond line of approximate thickness of 2 - 4 mm.

Remove the surplus adhesive from the sides of the laminate.

After 24 hours, when the adhesive has cured, test for voids by lightly tapping the laminate with a small hammer.

Cleaning

Clean tools and remove any uncured adhesive using webertec solvent 3.

Packaging, Health & Safety

Packaging

Supplied in 150 m rolls ready for use. The webertec force trestle is available seperately to safely unroll the carbon fibre plate laminate. The laminate can be pre-cut at the factory to suit the project needs.

Please advise at the time of order whether the laminate is required in cut lengths or in a roll.

Storage and Shelf Life

Store in dry conditions.
Protect from exposure to direct sunlight.

Unlimited shelf life.

Health and Safety

Carbon-fibre reinforced plate.

Loose fibres are sharp, strong and irritating. Always wear leather gloves when handling carbon-fibre plates and avoid contact with the skin.

Laminate plate is naturally flat, and when delivered in roll form, is under significant tension. To avoid injury to personnel, unroll and dispense CFRP laminates with a purpose made weber trestle.
