论文摘要
使用盐水夹的火星和月球岩石模拟物的圆柱标本模制，并在各种温度下烧结，以比较微观结构，机械性能和收缩。使用光学显微镜报告了材料显微结构，并使用MTS通用测试机进行材料测试。使用MARS Global Simulant（MGS-1），并使用Lunar Mare Simulant（LMS-1）执行了两次实验协议。标本是通过注射模制方法制造的，该方法旨在复制典型的梅森植物单元以及粘合剂喷气技术的绿色阶段，这是一种重要的添加剂制造（AM）技术。结果表明，对于火星和月球岩石，最佳的烧结温度在1100 c至1200 c之间。火星和月球森林样品的抗压强度都确定为最佳的烧结条件，被确定为建造外星人的构造。这项工作表明，火星和月球雷果均表现出有可能用作额外的陆地梅森氏菌，并用作额外的陆地BJT增材制造过程的父材料。
Cylindrical specimens of Martian and Lunar regolith simulants were molded using a salt water binder and sintered at various temperatures for comparing microstructure, mechanical properties and shrinkage. Material microstructure are reported using optical microscope and material testing is done using an MTS universal testing machine. The experimental protocol was executed twice, once using Mars global simulant (MGS-1), and once using Lunar mare simulant (LMS-1). The specimens were fabricated via an injection molding method, designed to replicate typical masonary units as well as the green stage of Binder Jet Technique, an important additive manufacturing (AM) technique. Results show that for both the Martian and Lunar regolith that the optimal sintering temperature was somewhere between 1100 C and 1200 C. The compressive strength for both the Martian and Lunar masonary samples, that received optimal sintering conditions, was determined to be sufficient for construction of extraterrestrial structures. The work demonstrates that both the Martian and Lunar regolith show potential to be used as extra terrestrial masonary and as parent material for extra terrestrial BJT additive manufacturing processes.
