dry carbon is pre-preg. That means the resin is impregnated into the carbon. You put it in an autoclave that adds heat and pressure. Most of the resin is then baked off. There is 2 type of wet layup. Open molding and closed molding. Most hood companies use open molding. Which is the cheapest and easiest way to make them but they are also not that light. Closed molding could be normal vacuum bagging which will make a lighter piece and then their is vacuum infusion which is the process we use. Everything is put in the mold dry then immense vacuum pressure is added. Then you inject the resin into it. This makes an air free lighter then most laminate. This is pretty much the closest to dry. There is pre-preg fiberglass as well so you can do carbon and fiberglass dry parts.
