WOW! Impressive. But I thought that NTPT was not
unidirectional - rather the leaves were layered at 45 degree angles to one another in a rotational form. Hence giving that extra rigidity?
Could have that wrong, but sure that is what I was shown and told in Switzerland. Hence the similarity with the Lotus use of the same materials.
However, I do know that NTPT in unidirectional form is used in sails.
Thanks for the interesting class!
