What's the density of carbon nanotubes?

02 February 2018 0 7K Report

I want to run simulation about carbon nanotubes, and I found the density info of CNTs from the website(https://www.cheaptubes.com/product/multi-walled-carbon-nanotubes-8-15nm/).

I was wondering what is bulk density, and what is true density. Which density should I use for FEA simulation?

Thanks!
