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.

You shouldn't need to use a heat gun on a composite part to remove it from the mould. Too much heat on a part is likely to make it soften (if it hasn't been post cured yet) which may well ruin the part.

I got the part out last night. but a lot of the blue release agent is on the mold piece. and area's that are coned upwards didn't get enough epoxy. I will upload a picture.
