Alkali-resistant glass fibre sheet for impact resistance and containment reinforcement

Product Features

About this Product

webertec force glass sheet is a bi-directional 50/50 or 90/10 woven glass-fibre sheet used for reinforcement and column wrapping. Manufactured by S&P,Switzerland, the sheet is ideal for impact resistance and containment of structural members under sudden impact.

Applied with webertec force EP primer and webertec force EP bonding adhesive to form part of the webertec composite strengthening system.

Features and Benefits

  • Low modulus fibre allows larger deformation leading to redistribution of the tension force
  • Containment fabric preventing loss of section during deformation
  • Versatile and easy to handle
  • Lightweight and easy to apply
  • Flexibility in applying the sheet allows it to be moulded around different shapes
  • Easy to handle and easy to cut to shape on site

Preparation & Application

Preparation

Before the application of the S&P G Sheet, 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 glass fibre sheet into the bearing substrate a tensile surface strength of at least 0.4 N/mm2 is required.

The bearing substrate shall be roughened by light grit blasting or sand blasting or grinding. Any unevenness must be tested with a straight edge. Maximum deviation shall be 1 mm per 300 mm.

The edges of the structural member must be rounded by grinding to acheive minimum radius of 15 mm.The substrate shall be cleaned of any dust and the moisture content shall be less than 4%.
Ensure all surfaces are clean and free from any contamination.

Application

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 touch-dry - normally up to 2 hours.

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.

Immediately after the adhesive is applied, the first layer of glass fibre sheet is applied by hand and pressed into the surface with a rubber roller and squeege.

Another layer of adhesive is applied by brush or roller over the first layer and is pressed into the sheet with a squeege. Additional layers are applied in the same way onto uncured, wet epoxy resin adhesive.

For multiple layers, use the wet lay-up process. Pre-wet the aramid sheet with webertec force EP bonding adhesive and place the wetted-out sheet onto the first coat of adhesive.

Roller and squeege into position, taking care to align the fibres correctly.

Encapsulate this layer with a second coat of webertec force EP bonding adhesive.

For multiple layers, repeat the above steps.

Pre-wetting of the glass 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.

Allow the epoxy resin adhesive to fully cure.

Cleaning

Clean tools carefully, using webertec solvent 3.

Packaging, Health & Safety

Packaging

S&P G Sheets are supplied in 50 m length rolls at 680 mm width.

Coverage / Yield

Area coverage is 34 m2 per roll.

Storage and Shelf Life

Store the glass 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.

For further information, please request the Material Safety Data Sheet for this product.Always wear gloves when handling fibre sheets, avoid contact with the skin.
