Abstract
A shock resistant body comprises a non-metallic lattice structure having a first region with a first foam density in a first region and a second foam density in a second region that is lower from the first foam density. The first region has solid lattice members of a larger cross-sectional area than those in the second region and the first region has smaller interstices between solid lattice members than those in the second region.
Claims7
A shock resistant body comprising:
- a non-metallic lattice structure having a first foam density in a first region and a second foam density in a second region that is lower than the first foam density;
- wherein the first region comprises a constant foam density, wherein the second region comprises a constant foam density, and
- a transition region between the first and second regions, wherein the transition region has a foam density that transitions from the first foam density to the second foam density in a direction from the first region to the second region forming a density gradient.
