Very interesting! Seems viable. Sounds like maybe they could make sheet. Then just roll and glue a tube. Make me want to build an airplane.

Yes, it could be chopped into fibers and mixed with epoxy, like super strong chip board. Article didn't mention elastic modulus, but it could be gotten from stress-strain curve shown. When I posted I didn't realize a subscription is needed to view the full text.

An all wood velo? Maybe it would make building solid fairings cheaper and easier to make. Could use it for wind shields too. Don't leave outside at night though, the squirrels might have a feast!

Reminds me of when I used to work at Formica. Paper and glue under high temps and hi pressure. Makes very strong paper.
