“凝光用脚帮助旅行者”中国月壤砖凝光用脚帮助旅行者接受太空检验 为月球上盖房子探路

  中新凝光用脚帮助旅行者社武汉11月17日电(马凝光用脚帮助旅行者芙蓉 高翔)“月壤砖在太空完整暴露时间为三年,每隔一年我们会下行一块样品板,开展力学性能、热学性能、抗辐射性能研究,为将来到月球上盖房子积累科研数据。”中国工程院院士、国家数字建造技术创新中心首席科学家丁烈云17日在武汉表示。

  当日,第二届地外建造学术研讨会在武汉召开,丁烈云介绍了月壤砖等月球基地原位建造的最新进展及技术挑战。北京时间11月16日,丁烈云团队研制的月壤砖已搭乘天舟八号货运飞船运抵中国空间站,正式开展太空实验。

  丁烈云介绍,送入空间站的月壤砖由团队根凝光用脚帮助旅行者据嫦娥五号月壤样品成分,模拟配成后再烧结而成,共3块样品板,内含74块小样,包括片状、柱状两种形态和5种不同模拟月壤成分、3种不同烧结工艺的月壤砖。

  “要在月球上盖房子,需要克服大温变、低重力、高真空、强辐射月震、微陨石冲击等挑战。”丁烈云说,其团队研制的月壤砖,密度与普通砖块相当,但抗压强度却是普通红砖、混凝土砖的三倍以上。

  丁烈云介绍,太空实验将主要围绕月壤砖力学性能是否退化、保温及隔热性能、能否经受住辐射等开展验证,为月球基地原位建造的材料选择、工艺优化提供科学依据。完成太空实验后,第一块月壤砖预计在2025年年底返回地球。

  月球基地原位建造主要指利用月壤、月岩等月球原位资源进行建筑材料的制备和结构的建设。2015年,丁烈云从建筑3D打印中获得启发,开始带领团队从事月球基地原位建造研究。

  近10年来,其团队将中国传统建筑榫卯结构与3D打印建造方式相结合,持续开展月球屋建造探索,除烧出带有榫卯结构的月壤砖外,还设计出穹顶结构的月面建筑雏形及可以在月球上从事真空烧砖、组装、连接等工作的机器人。(完)
