Abstract

The invention relates to lunar regolith concrete suitable for being extruded and a preparation method thereof, and the lunar regolith concrete suitable for being extruded and the preparation method thereof are mainly used in the technical fields of aerospace, aviation, building coatings and the like. A lunar regolith 'concrete' hybrid 3D printing technology is an important key technology in the future lunar follow-up lunar surface base construction. A lunar regolith simulant hybrid 3D printing device can realize continuous and controllable lunar regolith 'concrete' extrusion molding by designing a lunar regolith simulant hybrid 3D printing head. The hybrid 3D printing head is the key component of the lunar regolith hybrid printing device and is used for realizing continuous and controllable extrusion of lunar regolith 'concrete'. The device is a functional assembly integrating parts such as a driving motor, a coupler, a screw pump, a connector, a screw extrusion device and a printing nozzle into a whole, so that the continuous and controllable extrusion molding of the lunar regolith 'concrete' material is realized.

Description

technical field [0001] The invention relates to a lunar soil "concrete" suitable for extrusion and a preparation method thereof, which are mainly used in technical fields such as aerospace, aviation, and architectural coatings. Background technique [0002] my country's Chang'e lunar exploration project development plan has successfully completed the two stages of "circling" and "falling", and is about to start the third stage of "returning". Establishing long-term living and scientific research bases on the moon is becoming more and more achievable plan. The establishment of large-scale moon-based facilities can bring many benefits. It can rely on the advantages of the moon’s lack of atmosphere to better carry out scientific activities such as space observation. It can become an outpost for human beings to engage in scientific research in the future, and it can exploit the rich lunar soil resources that exist on the moon. , can rely on the moon as a platform to provide imp...
