Technical data
Preparation
The carbon plates as supplied have a layer of peel ply release fabric on all external surfaces. The purpose of this material is to ensure that the bonding surface (and all other surfaces) remains clean and uncontaminated.
The peel ply layer is a glass or polyester scrim material which to all intensive purposes looks to be an integral part of the panel. The resin from the panel manufacturing process will have flowed into the fabric, effectively binding it to the panels surface.
Before removing the peel ply, all other preparation work on the mating surface should be completed.
Where possible apply the adhesive to the beam before removing the peel ply from the panel.
To remove the peel ply fabric, tear the entire layer from the surface of the panel making sure that any overlapping areas have been removed and that no fibres or small areas remain. At all times ensure that only the peel ply surface material is being removed and not the adjacent carbon/glass layers.
After the peel ply has been removed, great care must be taken not to contaminate the panel’s surface.
Application
After the peel ply has be removed and the panel inspected, the panel is ready to be bonded. Ideally the panel should be bonded within 2 to 3 hours of the peel ply being removed.
Adhesive should be applied to the carbon panel and the surface to be bonded to unless otherwise stated.
Finishing
Unless the panels have become contaminated no cleaning of the panel is required by the contractor.
If the panels have become contaminated then specific advice must be obtained from the manufacturer as to an acceptable cleaning/preparation regime.
Storage and Shelf life
The panels should remain crated and be stored in cool dry conditions. The panels must be stored in these conditions until immediately prior to installation.
Stored correctly the panels will have an almost indefinite shelf life.

Packaging
The general packing of the panels is bubble wrapping of individual plates followed by wooden crate.
In addition, the exposed carbon surface is covered in peel ply release glass cloth, which appears to be an integral part of the surface of the panel. At all times the plates should be supported adequately over their entire length. When lifting/jacking/bracing in position, spreader plates/packers should be used to avoid point loading of the plate. Under no circumstances should the plates be subjected to any form of either local or systemic shock loading. When lifting into position it should be remembered that the plates can be of a fairly significant mass depending on their size. At all times clean leather gloves should be worn to ensure that the plates remain clean and that any sharp panel edges do not cut hands
