  Schwarzites are crystalline, 3D porous structures with stable negative
curvature formed of sp2-hybridized carbon atoms. These structures present
topologies with tunable porous size and shape and unusual mechanical
properties. In this work, we have investigated the mechanical behavior under
compressive strains and energy absorption of four different Schwarzites,
through reactive molecular dynamics simulations, using the ReaxFF force field
as available in the LAMMPS code. We considered two Schwarzites families, the
so-called Gyroid and Primitive and two structures from each family. Our results
also show they exhibit remarkable resilience under mechanical compression. They
can be reduced to half of their original size before structural failure
(fracture) occurs.
