I don't think Louis meant a laid-up resin cloth composit. I assumed he
meant the cloth itself--I used to use asbestos cloth as a heat shield, but,
of course, that's no longer considered acceptable. If you're going to buy
cloth, I would think glass cloth would be preferable. A few strands might
melt in a direct flame, but the stuff wouldn't catch fire. Carbon fibre is
carbon, is it not? Even diamond (also carbon) burns up in a fire.
