We kow carbon fibar it's very expansive. Expansice to produce the fabric sheets, and expansive (slow time consuming) way to work with.
Bu I remambered about two interesting news about carbon fiber, about possible dramatically reduce cost of manufacture and cost of working labor, one from my country Brazil, and other from EUA ands other researchs.
The brazilian research developed a carbon fiber made from petroleum tar, with very reduced cost,
about 15 dollar per kg.

(I didn't found a english news about it, so use translator)
The other research is finding ways to better and faster place and shape layers of carbon fiber, by using powerfull infrared lasers. Article from 2016, but since 2010 or so they talk about use of lasers.

If both researches get succcess, we can predict a near future with a lot of carbon fiber being used in many more aplications. Let's cross fingers.
I know carbon fiber aone it's not ideal, since it's not very eleastic and bracks suddenly insteadof bend first. But it can be used combined with other materials for reach specific goals.
