An Nylon lattice structure with improved mechanical property and energy absorption capability

Abstract

To study the mechanical behavior and energy-absorption capability, different lattices structures were designed and fabricated by using SLS technology with a raw material of Nylon. The quasi-static compression experiment and finite element simulation revealed the mechanical response and deformation mechanism of these structures. Meanwhile, the energy absorption capacity of the lattices structure was assessed by the impact resistance and corresponding calculations of specific energy absorption. The different design schemes were compared and analyzed under the same conditions. The results show that a minimal surface structure (MSS) has the best performance of compression properties. The designed composite scheme composed of the MSS and the BCC structures effectively enhances the impacting-bearing capability and improves the energy absorption performances.
