Abstract

Over time, natural materials have evolved to be lightweight, high-strength, tough, and damage-tolerant due to their unique biological structures. Therefore, combining biological inspiration and structural design would provide traditional materials with a broader range of performance and applications. Here, the application of an ink-based three-dimensional (3D) printing strategy to the structural design of a Lunar regolith simulant-based geopolymer (HIT-LRS-1 GP) was first reported, and high-precision carbon fiber/quartz sand-reinforced biomimetic patterns inspired by the cellular sandwich structure of plant stems were fabricated. This study demonstrated how different cellular sandwich structures can balance the structure–property relationship and how to achieve unprecedented damage tolerance for a geopolymer composite. The results presented that components based on these biomimetic architectures exhibited stable non-catastrophic fracture characteristics regardless of the compression direction, and each structure possessed effective damage tolerance and anisotropy of mechanical properties. The results showed that the compressive strengths of honeycomb sandwich patterns, triangular sandwich patterns, wave sandwich patterns, and rectangular sandwich patterns in the Y-axis (Z-axis) direction were 15.6, 17.9, 11.3, and 20.1 MPa (46.7, 26.5, 23.8, and 34.4 MPa), respectively, and the maximum fracture strain corresponding to the above four structures could reach 10.2%, 6.7%, 5.8%, and 5.9% (12.1%, 13.7%, 13.6%, and 13.9%), respectively.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
