Default DIY Carbon Fiber Parts Info Needed.

So I'm trying to figure out certain methods as far as making carbon fiber Parts & what everyone is using. Wax, PVA, modeling Clay, Gel, Resins, Carbon twill, etc...

I'm fairly new to the whole mold making process, and any info would be much appreciated as far as going about on how to. I know of Vacum pressing it, Pre-preg and that's about it.

Making a mold for my 06 Wagon Center Console then going to DIY and make some Carbon pieces for my interior if all goes well.

Thanks - Ben

Been covered on here before.
Some depends on how big a part.
Some depends on doing one or many.

Straight up copy, just doing in CF is the same as fiberglass. I sometimes wrap the original part in saranwrap, then cover with plaster of Paris. Let cure, remove part.
Smooth out "mold", clearcoat, let cure, then start my layup.
Bigger parts I may use GreatStuff foam instead, then a filler to get a good surface, then layup.

Polyester resin can be cheaper/easier, epoxy resin is usually stronger but costs more.

Interesting, I've never seen or heard about the saranwrap method. How does that hold up?

What's the point of clear coating it? It to leave that glossy looking finish? Or just used as a extra protectant?

Plastic wrap makes it easier to remove the "mold", especially on a textured surface like plastic interiors where you want to save the original piece. Wax or mold release can be a PITA to clean up later.
The plastic wrap may have small folds when you make the mold, so these need to be filled and smoothed before using the mold.
The clear (or really almost any paint, usually enamel) just gives a smooth finish to the mold that you can put mold release on.

Although not ideal, for one off smaller parts, you can use sheet metal. Just can't bag it unless you figure out how to reinforce it. On a new mold, apply at least 3-5 coats of mold release wax followed by a few good coats of pva. You should try to spray the pva if possible and will need a larger tip gun to do so. For making fiberglass molds I suggest you find the salty old guy on youtube that makes a trunk for a harley. You'll need tooling gel coat (also should be sprayed and thoroughly mixed. requires special gun to spray) woven cloth, chopped strand mat, poly resin, tools.

Use epoxy resin for carbon.

Edit: youtube guy is GasserGlass. You'll learn a lot.
