Figure 3: Mechanical properties of FIBER NFAs with various densities.

From: Ultralight nanofibre-assembled cellular aerogels with superelasticity and multifunctionality

Figure 3

(a) The relative modulus (defined as the measured Young’s modulus, E, divided by the Young’s modulus of the constituent solid, Es) of selected cellular materials at low relative densities. (b) A 20-cm3 FIBER NFA (ρ=0.12 mg cm−3) stands on the tip of dyed feathers. (c) Photographs demonstrate that the ultralight FIBER NFAs (ρ=0.12 mg cm−3) can even float on cold air.
