If you want carbon bits for your car, you need to speak to these guys:

http://www.fluke-motorsport.co.uk

Anything you want that isn't listed, they can probably get made for you.

They are guys. They have just packed their slightly special Westfield off to Barbados to compete in the Barbados Rally Carnival over there for the 3rd year in a row.

Their car has an R1 bike engine and is pre-preg carbon fibre all over.

Cold molding is pretty easy to do.
We make up parts (for boats) using a vacuum bagging technique and E-glass or carbon fiber and West Epoxy.

Youll need a vacuum pump that can pull about 10" of vacuum. Kits occasionally appear on Ebay for this exact purpose or you can build your own with PVC pipe, beverage tubing and a small pump.
Make sure you make it pressure adjustable though, and you might want to add a manifold that you can fill with cotton batting to catch any epoxy that the tubes might suck up so you dont wreck your pump (not that I've ever done that).

We buy carbon fiber in bulk but I'm not sure where from right now, I could find out tomorrow.
It'd be in the US though.

Excellent you got any websites or books i could get to give me an idea on how i do it.

I intend to make up moulds for the parts i have on the car at the moment but after that i have not got a clue on how to proceed.

Do you put the whole moulding in a bag and then pull a vacuum on that bag. Do you need speacil bags or can you use anything.

I haven't got a vacum pump but can probably cobble something together to pull 10" of vacuum can't remeber what that is in Kpa as that is what i am more used to.

Don't suppose you have a Massachusetts source for prepeg?

Well you dont really use a bag per-se. We just use poly plastic sheeting cut to fit. One piece on the workbench and the other piece over the top of the part, with some batting/breather fabric and another fabric called peel-ply. You stick the two pieces of poly together with something that we call "monkey-[censored]" but is just a sticky kind of dope. Kinda like what you would use to seal up leaky windows on your house.

I haven't got a vacum pump but can probably cobble something together...
We've got a nice homebuilt one that one of the guys put together. Ill see if I can take a couple of pics of tomorrow, and get the specs for the pump too.

I cant think of any websites off the top of my head, but we have this book by the Gougeon brothers at school, and its really good at describing the different processes for using epoxy and glass. Gets a little technical in regards to boat construction though.
The Gougeon brothers (innovated epoxy/glass techniques founders of WEST System epoxies) also have a couple of short paperback pamphlet/manual type books on glasswork. The one that comes to mind is called "Vacuum Bagging Techniques". That would be a really good one to start with. (Its listed about half to 3/4 of the way down the page in the link below)

This site that I just found has everything you'd need to get started.
Never shopped there myself, but the page above has everything that we use everyday.

Ill take a walk around the shop tomorrow and see if anybody's got anything laid up.

Hmm...
We're in Maine so I'm not sure where we get ours.
I can check for you though.
