论文摘要
在设计航空航天和防御区域的高负载结构时,特定的强度(强度/密度)是至关重要的因素。通过与高强度成分混合,或通过高强度填充剂组合,可以增强材料的强度,但两种选项都有局限性,例如在某些负载下,由于填充较差和矩阵相互作用而导致材料失败。因此,研究人员有兴趣通过使用拓扑/几何形状来增强材料的强度,因此自然是模仿结构的最佳选择,而复杂性限制了模仿结构的自然界。在本文中,我们探索了沸石启发的结构,以实现载荷能力。沸石启发的结构是从分子动力学模拟获得的,然后通过融合沉积建模制造。使用3D打印实验合成了来自模拟的原子量表复杂拓扑。沿不同方向测试了制造结构的可压缩性,并与模拟结果进行了比较。这种复杂的建筑可用于超轻型航空航天和汽车零件。
Specific strength (strength/density) is a crucial factor while designing high load bearing architecture in areas of aerospace and defence. Strength of the material can be enhanced by blending with high strength component or, by compositing with high strength fillers but both the options has limitations such as at certain load, materials fail due to poor filler and matrix interactions. Therefore, researchers are interested in enhancing strength of materials by playing with topology/geometry and therefore nature is best option to mimic for structures whereas, complexity limits nature mimicked structures. In this paper, we have explored Zeolite-inspired structures for load bearing capacity. Zeolite-inspired structure were obtained from molecular dynamics simulation and then fabricated via Fused deposition Modeling. The atomic scale complex topology from simulation is experimentally synthesized using 3D printing. Compressibility of as-fabricated structures was tested in different direction and compared with simulation results. Such complex architecture can be used for ultralight aerospace and automotive parts.
