In this tutorial we demonstrate how to create a forged carbon fiber cured sheet with a double sided satin finish using non-porous Teflon coated peel ply, glass plates and vacuum bagging. The material used here is Gold Standard Forged Carbon Fiber Fabric, but this method can be used with any of our forged carbon dry fabrics.

Details
1. Forged fabric is cut to the size of the tempered glass plates using a rotary cutter. The non-porous Teflon coated peel ply is cut slightly larger to prevent breather cloth sticking to the edges of the carbon/glass.
2. Deep Set Epoxy Resin has been degassed in a vacuum chamber to remove air bubbles, and then a heat gun is used to reduce bubbles introduced during the application process. Amount of resin mixed for this project was approximately 1.2 x the weight of the dry fabric.
3. Glass should be coated with a release agent such as wax to protect against excess resin squeeze out.
4. Peel ply and glass must be free of dust when placed together as even a small particle between the surfaces will create a dimple in the finished plate.
5. This method generally yields a pinhole free, lightly textured surface. Surface imperfections can typically be avoided by thoroughly pressing/rolling the sheets before adding the glass backing plates. Also, reducing the vacuum level to approximately 8" Hg may reduce voids while still providing adequate compression. If necessary, imperfections can also be filled after initial cure by spreading a thin coat of resin over the surface, adding peel ply, rolling to remove air pockets, topping with glass and allowing to cure.
