Carbon nanotubes is not best armor material on earth

[nick87720z]

I just discovered carbon nanotubes could be not best armor material against alien weaponry (even today).
Hope it will make sence to be noted here .

This link is from CNT wiki page:
https://en.wikipedia.org/wiki/Boron_nitride_nanotube

It's claimed to have same mechanical properties (or at least tensile strength - not sure if it same about others, including pressure resistance), but higher thermal stability - CNT is claimed to fail at 400°C with BNNT at 90°C.

One publication clames BNNT is even stronger than CNT.

Yet during previous search I noticed SiC nanotubes mentioned, but can't find anything about it with unrestricted read access. Everything I could find requires some login (for begining... did not try to go any further).
