摘要:

比强度(强度/密度)是设计航空航天和国防领域高承载建筑的关键因素。材料的强度可以通过与高强度组分共混或通过与高强度填料复合来增强,但这两种选择都有局限性,例如在某些负载下,材料由于填料和基质相互作用差而失效。因此,研究人员有兴趣通过玩拓扑/几何来增强材料的强度,因此自然是模仿结构的最佳选择,而复杂性限制了自然模仿的结构。在本文中,我们探讨了沸石启发结构的承载能力。通过分子动力学模拟获得了类似于沸石的结构,然后通过熔融沉积建模进行了制备。使用3D打印实验合成来自模拟的原子尺度复杂拓扑。测试了不同方向的压缩性能,并与模拟结果进行了比较。这种复杂的结构可用于超轻航空航天和汽车部件。

英文摘要:

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.
