Contour you refer to curing carbon fiber. In all my years of building race kayaks (that's what I did for work) with carbon fiber cloth, I never heard of a person paying attention to moisture content. The stuff comes in a roll from the factory. It takes on whatever the relative humidity of the work shop is (in time). I would not worry about curing. Unless you are talking about the curing of the epoxy used to bind the fibers. Then you should just read the manufacturers literature. For any natural fiber like wood, sisal, hemp, you can not go far wrong with WEST SYSTEMS epoxy. It's formulated for wood boats. There are other equally good products available however. In time you will find there is very little magic in working with composites, natural or man made.
