Hi,

I make carbon fiber fins for freediving
with OOA prepreg twill 200 gsm
I use a mold and a counter mold in press
and a heating system under the mold

The issue I am having:
Sometimes my part comes out curved lengthwise instead of being perfectly flat.

If anyone has an idea of to solve this issue it will help me a lot.

Thanks

Hi,

Thanks for you advices.

I'm using Twill 0 90° only (9 plies)
There is a temperature controller on the mold.

I will check the temperature on each side this week-end .
