“…Two materials were used to verify the performance of this model: Lunar Mare Simulant 1 (LMS-1) (Exolith Lab) and dry sand (40-100 mesh, CAS: 14808-60-7, Fischer Scientific). LMS-1 is a readily available lunar regolith simulant which is commonly used in research (Stupar et al, 2021;Isachenkov et al, 2022;Meurisse et al, 2022). It was chosen for this work due to its well documented physical properties (Long-Fox et al, 2023), including the density, cohesion and friction parameters required for this model.…”

Introduction: Physical regolith simulants are valuable tools for developing In-Situ Resource Utilisation hardware. However, using virtual models of regolith instead can reduce costs, limit exposure to hazardous materials, and offer a practical method of testing the effects of reduced gravity.Methods: We verify a virtual model of regolith as macroparticles against physical tests. Using space partitioning techniques to identify neighbouring particles, we present a scalable model of regolith, in which the computation time increases roughly proportionally with the number of particles. We evaluated the performance of this virtual simulant vs. a physical simulant (Exolith LMS-1) by comparing the flow rate through funnels of various diameters, and the resultant angle of repose of material on both large (500 g) and small (16 g) scale tests.Results: For large scale tests, the flow rates were within the predicted range for macroparticles with radii 3–7 mm, with the greatest accuracy achieved for radii 4–5 mm. However, the macroparticles blocked the simulated funnels more easily than in the physical trials, due to their high cohesion. The angle of repose was not accurately represented by this model for either of the tests.Discussion: The high efficiency of this model makes it best suited for applications which require large scale approximations of regolith with real-time execution, such as virtual training for robot operators or providing visual and haptic feedback in model-mediated teleoperation systems. The results of this model in reduced gravity could be further verified against data from upcoming lunar missions in future work.

“…The raw materials for the fabrication of HIT-LRS-1 included basalt powder (Hebei Runhuabang New Material Technology Co., Ltd., China), plagioclase powder (Shijiazhuang Shuoheng New Material Technology Co., Ltd., China), forsterite powder (Henan YanXi Mineral Products Co., Ltd., China), albite powder (Shijiazhuang Shuoheng New Material Technology Co., Ltd., China), ilmenite powder (Qinghe County Benyu Metal Material Co., Ltd., China), hematite powder (Shanghai Macklin Biochemical Co., Ltd., China), silica powder (Shanghai Macklin Biochemical Co., Ltd., China), alumina powder (Shanghai Macklin Biochemical Co., Ltd., China), and cristobalite powder (Shanghai Macklin Biochemical Co., Ltd., China) [37]. The main chemical compositions of the Lunar regolith simulant are based on SiO 2 , Al 2 O 3 , Fe 2 O 3 , MgO, Na 2 O, TiO 2 , etc., and the content of the amorphous phase is about 30% or more [8]. The Lunar regolith simulant synthesis is referred to Refs.…”

“…As a potential alternative to cement, geopolymers have attracted widespread attention due to their low density, low thermal conductivity, and the possibility of using a wide range of raw materials for their fabrication [5,6]. The most outstanding advantage of using geopolymers for the Moon construction is that the raw materials can be obtained from Lunar regolith, avoiding the high transportation costs of transporting cement from the Earth to the Moon (in situ synthesis of geopolymers on the Moon can be accomplished with only little quantities of extra materials delivered from the Earth) [5,7,8]. Related studies [5,9] have demonstrated that active substances in Lunar regolith are suitable for geopolymerization, as they provide the necessary Si and Al sources for the thermodynamically favorable formation of amorphous aluminosilicate networks, once subjected to alkaline attack.…”

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.

“…The resin is stored in a tank (Vat) which is exposed to ultraviolet (UV) light to turn the liquid layer into a solid. The object is created initially using any modelling software and then the printer uses digital light processing technology to project the model with the help of UV light onto the liquid photopolymers layer by layer [71][72][73]. The build platform will move downwards after every layer is formed.…”

Thin-walled energy absorbing structures based on hybrid structural concepts have a lightweight benefit along with great potential of enhancing the crashworthiness characteristics. Inspired by the huge number of research investigations performed on novel additively manufactured hybrid metal-composite configurations and their latest developments, the current review article extensively reports the latest advances along with promising outcomes of the impact response of various additively manufactured hybrid metal-composite structures for crashworthiness applications. Specific consideration is given to the crushing performance of the hybrid structures fabricated from Fused deposition modelling technique. The significant additive manufacturing techniques, their material selections and exceptional customized structural designs explored in recent times are discussed elaborately. Crushing patterns obtained by hybrid energy absorbing structures under various loading conditions are recognized. Furthermore, comparison of various hybrid structures and their latest advances revealed the efficiency of the thin-walled hybrid configuration based on 3D printing techniques in terms of weight reduction, crashworthiness and energy absorption behaviour. This review article will serve as a catalyst to boost the scientific improvement of hybrid energy absorbing structures utilized as passive safety protective devices in modern vehicles.
