Abstract

Metal lattice structures fabricated by additive manufacturing (AM) processes combined with polymers provide hybrid materials with unexpected mechanical properties. In particular, this article investigates the increased capability of absorbing elastoplastic energy of the composite material, which is up to 75% higher than the sum of energies absorbed by each constituent material. Furthermore, the fabrication process to obtain reliable and repeatable hybrid components by filling the 316 L metal lattice with polymer is introduced and validated.

基于具有能量吸收能力的聚合物填充 AM 钢格的混合材料

摘要

通过与聚合物相结合的增材制造 (AM) 工艺制造的金属晶格结构为混合材料提供了意想不到的机械性能。特别是，本文研究了复合材料吸收弹塑性能的能力增加，该能力比每种组成材料吸收的能量总和高出 75%。此外，还介绍并验证了通过用聚合物填充 316 L 金属晶格来获得可靠且可重复的混合组件的制造工艺。
