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, 
The mold was hotter on the ends than in the middle.
I changed the position of the heating elements.

The parts are now perfectly flat :-)

Thanks a lot for the help.
