摘要
月球基地建设是人类开展深空探测的初步任务,原位利用月球资源对于实现月球基地建设具有重要意义.本文以月球基地建设中对高性能材料的需求为出发点,研究了模拟月壤的组成、晶相结构、熔融特征和成纤行为.研究结果表明,月壤与地球玄武岩矿石具有相近的化学成分和矿物相组成,模拟月壤在1332℃完全熔融并在淬冷后转化为非晶态玻璃体.采用熔融-牵引法获得了单丝拉伸强度超过1400 MPa的月壤基连续纤维,该强度接近目前商业化的玄武岩纤维.研究结果证实原位利用月壤制备连续纤维具有一定的可行性,基于月壤纤维增强的复合材料有望为未来月球基地建设提供原材料保障.
The construction of a lunar base is considered to be a giant step for the deep-space exploration by human beings. The in situ utilization of lunar resource is essential for the realization of this ambitious plan. In this study, the composition, crystal structure,melting, and fiberization behaviors of lunar soil simulant were investigated in an effort to develop a continuous fibre to address the material requirements for building a lunar base. The results showed that the chemical and mineral composition of the lunar soil simulant were similar to those of basalt roes on the Earth, and the material could be completely melted at 1332℃. The crystal structure of the simulant was homogenized and transformed into the amorphous glass state when the melted material was quenched by water. Using a fibre spinning facility, continuous filaments were obtained using the melted lunar soil simulant as the raw material. The obtained fibre showed the tensile strength of more than 1400 MPa, which is comparable with that of a commercial basalt fibre. These results confirmed the feasibility of using lunar soil to prepare a continuous fibre for the construction of a lunar base.
