I'm new and just getting into carbon fiber work. I did my first mold and ended up with little success. My carbon fiber ended up gluing to my mold. This time i put 4 heavy coats of pva release agent to try and avoid this. What I really want to find out is making split moulds. Many of the parts i want to produce carbon fiber copies of have plastic parts on the back. Was thinking of 3d printing these and gluing them on or a split mold of some sort. any advice is welcomed.

Welcome to the Forum!

Sticking parts in your mould is a common early mistake so in a way its good to have got that out the way now!  Good application of release agents is vital to releasing your parts.  It's good you learned that lesson now on a small part rather than a much bigger expensive part!

3D printing and bonding on the reverse fixings is a good way to finish the panels. The reverse fixings are a common issue for many when laminating and need to be considered on a case by case basis.  Some people will take a cast of the fixings, then bond them in place, others will fabricate a new fixing from scratch.  You can even bond in "big head" fasteners which will give you threaded studs/captive nuts etc which can help with refitting the panel.

Thanks. I found out if you use a heat gun on the plastic part when trying to take it out of the mold it shrinks the plastics and pops right out. Will this work when removing the carbon fiber piece from the mold?
