Abstract

Triply periodic minimal surface (TPMS) structures can produce tailored complex structures for various applications and serve as substitutes for polymeric foams. In this study, six different types of TPMS structures (Neovious, gyroid, Schwarz P, Lidinoid, split P, and diamond) were examined under quasi-static compression in terms of their energy absorption capabilities, mechanical properties, and weights, which were compared with those of expanded polystyrene foam and the original printing material Z-Ultra. It was found that the Neovious, diamond, and Lidinoid structures were most suitable for substituting expanded polystyrene foam, especially in safety helmets requiring high specific energy absorption capabilities.

三重周期最小表面 (TPMS) 结构可以为各种应用生产定制的复杂结构，并作为聚合物泡沫的替代品。在这项研究中，对六种不同类型的 TPMS 结构（Neovious、gyroid、Schwarz P、Lidinoid、split P 和 diamond）在准静态压缩下的能量吸收能力、机械性能和重量进行了检查，并进行了比较与发泡聚苯乙烯泡沫和原始印刷材料 Z-Ultra 相结合。发现 Neovious、金刚石和 Lidinoid 结构最适合替代发泡聚苯乙烯泡沫，特别是在需要高比能量吸收能力的安全头盔中。
