I have a problem, which i do not know how to solve. For my application i need a thin sheet of carbon fiber that is perfect finish on both sides.




I am using one layer of deltapreg 200g prepreg and vacuumed between two glass panells and than baked in autoclau on 4bar. The problem is no matter what i try i get pinholes on both sides, which are not acceptable. I have also tried with drg carbon with resin and the result is similar.




What can i do to get rid of the pinholes on both sides and get a perfect finish?

Are you making your carbon the same size as your glass panel ?,don't have any gap at the sides and flash tape all round the edge to stop any resin bleed
