theres two ways of doing it:

1 layer of carbon fibre twill matting at 120g/sm impregnated with epoxy is mega strong (at least as strong as 2 or 3 layers of polyester and chopstrand glass) and also very light for exanple a side panel would weigh about 500g. This is 'proper' structural carbon fibre like f1 parts etc. This is pretty expensive because epoxy is a pig to work with and because its so sticky and horrid the only way to get a perfect finish is to vac-bag everything, the tape and bags cost a fortune, and there is alot of wasted materials, another way is to use an autoclave which again pushes up the cost to the customer.

or

1 layer of carbon fibre twill impregnated with polyester, but due to the structural properties of polyester resin with cloth it would have to be backed up with chopped strand matting to give it some rigidity, so cosmetically its real carbon fibre, but its reinforced behind. This is the cheaper way to do it because no expensive epoxy is required, its alot easier to work with than epoxy and there is no need on most items for the vacumn pump. The weight works out about the same, if not a little lighter because you are replaceing say 1kg of gelcoat with the equivilent of 120-150gram of twill.
