Abstract

This study attempted the spark plasma sintering (SPS) method to consolidate lunar soil simulants and evaluated the SPS parameters such as sintering temperature and pressure on densification behavior and mechanical properties. Toward that end, a lunar simulant FJS-1 was selected, and the simulant was sintered at different temperatures and pressures. Test results of density, microstructure, and nanomechanical properties were compared to investigate the effects of varying sintering conditions. In general, it appeared that the SPS method could successfully densify the FJS-1 simulant at proper conditions, and the level of densification and development of microstructure and mechanical properties were dependent on SPS conditions (such as temperature, pressure). Mechanical tests results along with the microstructural characteristics imply that the SPS can be considered a promising in situ resource utilization (ISRU) method to densify lunar soils for potential space construction and architecture.
