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?

It would be mostly down to the cure cycle you are using. Here I had to make a couple of single layer sheets.
