I have been working with carbon fiber since this year so I'm still a rookie I would say. I doing some CF myself and I'm wondering if I could use pre preg to do laminations of the nterior trim ?

I have tried this. Sometimes it works and most times it does not.

The main issue is that the plastics expand a lot with heat, when the plastic parts have different thickness they expand different amounts so this will bend and change the shape of your parts.
