i didnt think you could get carbon fibre see-through, a light plastic?
Polycarbonate.
Been used on a couple of trackday and sprint specials. Most successfully the Lotus Expose - which is one of the coolest cars I've seen for a long time.
Apply thin paint and it's perfectly possible to be seethrough in certain conditions. It may not be strong enough to cope with F1 loads though. It can be used in a composite with Carbon fibre, but then it wouldn't be transparent.
