摘要

三维晶格结构由连接的片段网络组成,可根据需要对基材进行定位,同时保持开孔特性。这些结构是高性能夹芯板的理想轻质芯材。这项研究首次展示了使用拉挤碳纤维增强聚合物(CFRP)棒材通过间接增材制造方法制造的基于网格的芯材的性能。对 CFRP 夹层板进行了平面外压缩测试,并通过分析和有限元分析预测了其压缩性能和失效模式,随后与机械测试进行了对比。最后,该研究与文献中发现的类似芯材进行了比较。

Compressive behavior of Body-Centered-Cubic (BCC)-like ultra-lightweight Carbon Fiber Reinforced Polymer (CFRP) lattice-based sandwich structures

3D lattice structures comprise a connected network of segments that allow positioning of the base material where needed while maintaining an open-cell characteristic. These structures represent an ideal lightweight core material for high-performance sandwich panels. This work presents, for the first time, the performance of lattice-based cores fabricated via indirect additive manufacturing using pultruded Carbon Fiber Reinforced Polymer (CFRP) rods. The CFRP sandwich panels were tested under out-of-plane compression, and their compressive properties and failure modes were predicted via analytical and FE analyses, later contrasted with mechanical testing. Finally, the study compares favorably with similar core materials found in the literature.
