About this Product
webertec force carbon sheet is a uni-directional sheet for structural confinement reinforcement, manual wrap lamination and tensile strength reinforcement to structural members. Manufactured by S&P, Switzerland, the sheet is available in two grades and applied with webertec force EP primer and webertec force EP bonding adhesive to form part of the webertec force composite strengthening system.
Features and Benefits
- Lightweight and easy to apply
- High strength to weight ratio
- Minimal applied thicknesses
- Very flexible for details and easy to mould in situ around complex shapes
- Corrosion resistant
- Two grades of carbon fibre enabling selection in design
- Impact and blast resistant
- Factory produced with consistent mechanical properties
- Small, easy-to-handle rolls allowing precise location and embedment
- Unidirectional fibres allowing utilisation of high-strength fibres
- Special widths can be manufactured for specific projects
weber's Customer Services Department has a team of experienced advisors available to provide on-site advice both at the specification stage and during application. Detailed specifications can be provided for specific projects or more general works. Site visits and on-site demonstrations can be arranged on request.

Material Safety Datasheet
Preparation & Application
Before the application of S&P C sheets, the quality of the substrate has to be checked. The tensile strength has to be tested with a pull-off bond test. For load to be transferred from the carbon sheet into the bearing substrate a tensile surface strength of at least 1 N/mm2 is required.
The bearing substrate must be roughened by light grit blasting or sand blasting or grinding. Any unevenness must be tested with a straight edge. Maximum deviation is 5 mm per 2 metre.
The edges of the structural member must be rounded by grinding to acheive a minimum radius of 15 mm.The substrate must be cleaned of any dust and the moisture content must be less than 4%. Ensure all surfaces are clean and free from any contamination.
webertec force EP primer
The epoxy resin primer must be mixed in accordance with the product data sheet and applied to the prepared substrate. Allow to go tacky - normally up to 2 hours, but do not allow to dry.
webertec force EP bonding adhesive
The epoxy resin adhesive must be mixed in accordance with the data sheet and applied evenly to the primed substrate as a first coat.
Immediately after the adhesive is applied, the first layer of carbon fibre sheet is applied by hand and pressed into the surface with a rubber roller and squeegee.
Another layer of adhesive is applied by brush or roller over the carbon fibre sheet and is pressed into the sheet with a squeegee. Additional layers are applied in the same way onto uncured, wet epoxy resin adhesive.
For the C sheet 640, a wet lay-up lamination process will need to be employed. Pre-wet the sheet with webertec force EP bonding adhesive and place the wetted-out sheet onto the first coat of adhesive. Encapsulate this layer with a second coat of webertec force EP bonding adhesive. For multiple layers repeat the above steps.
Pre-wetting of the carbon fibre sheet can be achieved by either:
- 1 Manual lamination on a table protected with plastic sheeting.
- 2 Machine lamination using the webertec force laminator, details available on request.
For multiple layers of C240 sheet, use the wet lay-up process described above.
Allow the epoxy resin adhesive to fully cure.
Clean tools carefully, using webertec solvent 3.
Packaging, Health & Safety
S&P C Sheets are supplied in 150 m length rolls at 300 mm width and come with a protective plastic film for ease of handling.
Coverage / Yield
Area coverage is 45 m2 per roll.
Storage and Shelf Life
Store the carbon fibre sheets in dry conditions and protect from exposure to direct sunlight.
Unlimited shelf life if stored correctly.
Health and Safety
Sheet reinforcement material. Loose fibres may be sharp, strong and irritating. Always wear gloves when handling fibre sheets and avoid contact with the skin. Cut the rolls by applying adhesive tape across the width of the roll and cut with industrial scissors through the tape to avoid fraying loose fibres.
