Composites noob plaster mold question
(OP)
Hello all. I'm very interested in working with carbon fiber for automotive applications. My goal is to produce aesthetic and structural pieces. I think I've decided on vacuum infusion since I can't afford a large autoclave for pregreg. But before I go out and buy equipment and materials, I want to practice making molds first. I would very much like to use plaster molds versus fiberglass, but I'm not sure whether or not it is a suitable material for vacuum-infusion carbon fiber. If it is, what type would you recommend?
Any information you have would be greatly appreciated!

Fibre glass moulds will be a lot lighter and stronger than plaster.
It will be difficult to get good mould release from a plaster mould, so a lot of mould release wax might be needed. This might reduce the surface gloss and therefore require more effort in the finishing of the part.
