Be very careful when working with carbonfiber. Use a good resperator and gloves. Carbonfiber will never leave your body once in.

Thanks for the link for the CF supplier, that is a great price. :thumbs:
The finish of your parts is only going to be as good as the finish of your mold (if using a female mold). The more time you spend making sure your mold is perfect the better your finished parts will look.
The main reason for vacuum bagging a layup is to eliminate excess resin and make the finished part as lightweight as possible. A side benefit of this process is that it will sometimes help the fabric comform to complex shapes in the mold better than it would otherwise, but this is limited by the elasticityof the bagging material. If the cloth is not layed up correctly in the first place vacuum bagging will not eliminate voids and air bubbles.
The only way to get good at fiberglass and carbon fiber layups is to do it, talk to as many experienced people as you can and learn what techniques work for them. Try them all and find out what works for you. Practice, practice, practice. :smash:

I used to work for a company that mad multilayer flexible circiutry. We used a vacuum bug inside an autoclave. A couple of hundred PSI on the outside 0 on the inside and believe me there was no delamination :smash:
One trick we used was to cover the whole backside with this loose unwoven cloth ( we called it monkey fur ) this let us pull an even vacuum. Without it you would get air trapped in the bag, that doesn't work at all! A person could use a thin felt or polyester stuffing.
Get a good vacuum pump and make sure it pulls hard for a while before curing the prepeg.
Personally I think vacuum only is barely enough to do lamination...
