Abstract

In order to explore the dynamic splitting mechanical properties of fiber reinforced lunar soil simulant, polypropylene fiber and basalt fiber were used to prepare fiber reinforced lunar soil simulant based geopolymer disk specimens. Split Hopkinson pressure bar (SHPB) device was used to carry out impact splitting test, and the distribution and arrangement of fibers at the fracture surface of geopolymer were observed by scanning electron microscope. The test results show that when the polypropylene fiber content is 0.4%, the splitting tensile strength of the specimen reaches the maximum, which is 22.9% -27.3% higher than that of the undoped specimen. Under the same fiber content, the gain effect of polypropylene fiber on the splitting tensile strength of the specimen is better than that of basalt fiber; when the fiber content is constant, the dynamic splitting tensile strength of the specimen is positively correlated with the impact pressure, and the gain effect of the fiber on the splitting tensile strength is negatively correlated with the impact pressure. The test block splits into two relatively complete halves along the axial direction under the impact load. The incorporation of the fiber reduces the damage degree of the specimen and improves the brittle failure. The average particle size of the splitting fragmentation of the specimen increases with the increase of the fiber content. The research results provide a reference for the selection of construction materials for future lunar bases.
