Description

Composite wall structure applied to moon building
Technical Field
The invention relates to a composite wall structure applied to a moon building, and belongs to the technical field of moon building engineering.
Background
The moon is the first choice target for human beings to carry out deep space exploration, and the unique environment and resources of the moon make the moon an ideal place for carrying out basic researches on space astronomy, space physics, planet science, material science and the like. The development of manned moon exploration and the construction of moon buildings on the moon surface are important means and inevitable ways for realizing moon residence and moon resource development and utilization in the future of human beings.
The lunar surface living cabin can be divided into a rigid cabin and a deployable cabin according to different structural forms. The rigid cabin is usually made of metal materials, is processed, manufactured and assembled on the earth and then is conveyed to the surface of the moon through a moon transportation system, the maturity is high in the whole view, the technical difficulty is low, but the work and living space provided by the rigid cabin is limited, and if the cabin section needs to be expanded, material transportation between the earth and the moon needs to be carried out for many times, and the construction cost is increased. The expandable living cabin can be used after being expanded on the surface of the moon, and specifically, the expandable living cabin can be expanded by inflation or by machinery. The deployable capsule may be stowed in a collapsed configuration and is therefore less constrained in size to transport. Compared with a rigid cabin, the expandable cabin has lighter weight, better expansibility and more flexible application under the same cabin volume, but has higher requirements on materials and structures. If the expandable living cabin is adopted, multiple protection is needed to be carried out aiming at severe environmental factors such as space radiation, lunar surface high and low temperature, micro-fluid and the like from two aspects of material selection and structural design.
At present, the general protection means for space radiation, debris and micro-fluidic star impact in the aerospace engineering is to increase the thickness of the skin, and the biggest defect of the mode is to increase the weight of the cabin and the emission cost. For an expandable lunar building, at present, no composite wall structure scheme of a lightweight lunar building, which can comprehensively consider radiation, high and low temperature and micro-fluid protection and can combine lunar in-situ resource utilization, exists.

Detailed Description
The first embodiment is as follows: the embodiment is described by combining with figure 1, a composite wall structure applied to a lunar building comprises an optical fiber system prefabricated layer 8, a flexible inner film layer 7, an inflatable structure reinforced layer 6, a flexible heat insulation layer 5, a flexible protective layer 4, a lunar soil filling layer 3, a lunar soil reinforced layer 2 and a flexible solar energy surface layer 1 which are sequentially arranged, wherein the optical fiber system prefabricated layer 8, the flexible inner film layer 7, the inflatable structure reinforcing layer 6, the flexible heat-insulating layer 5 and the flexible protective layer 4 are prefabricated on the ground, the lunar soil filling layer 3, the lunar soil reinforcing layer 2 and the flexible solar energy surface layer 1 are all built in the moon, optical fibers are buried in the optical fiber system prefabricating layer 8 and are connected with indoor equipment through connectors, under the action of pressure, the inner membrane of the flexible inner membrane layer 7 surrounds to form a cavity and continuously forms a pressure keeping shape, and the aeration structure reinforcing layer 6 is made of polymer foam doped with simulated lunar soil and boron-containing compounds through foaming. The lunar soil filling layer 3 is a filling layer with equal density of lunar soil or simulated lunar soil (such as lunar soil bags or lunar soil bricks), and each layer of structure prefabricated on the ground is attached to the surface of the inflatable living cabin.
The optical fiber system prefabrication layer 8 is used for embedding the optical fiber in the coating layer, and the polyimide coating is used for the coating layer, so that the optical fiber can still be normally used at 300 ℃. The light external interface adopts PC model. The connector for connecting the indoor equipment and the optical fiber is a standard connector and is arranged on the surface of the prefabricated layer 8 of the optical fiber system. The thickness of the optical fiber system preform layer 8 is about 300-.
The flexible inner film layer 7 is a spacing layer between the aerogel-like insulation layer and the optical fiber system prefabricated layer 8.
The flexible protective layer 4 mainly plays a protective role, so that the monthly construction of the external layer is facilitated, and the abrasion damage of a machine to the flexible heat-insulating layer 5 is prevented when the external layer is constructed monthly; secondly, the lunar soil filling layer 3 can be fixed more tightly.
The solar surface layer positioned on the outermost side of the wall body mainly has the functions of absorbing sunlight and converting solar radiation energy into electric energy for the lunar building.
The lunar soil reinforcing layer 2 is made by 3D printing to form a high-strength and high-density shell, and the lunar soil reinforcing layer mainly plays a role in protecting an inner layer structure and bearing energy of space meteorite impact.
The lunar soil filling layer 3 has low thermal conductivity and mainly plays a role in heat preservation and radiation resistance. The material is lunar soil or simulated lunar soil, such as lunar soil bags or lunar soil bricks, and the lunar soil is prepared by utilizing collected lunar soil in the moon by a lunar robot.
The inflatable structure reinforcing layer 6 plays a role in structural reinforcement by utilizing the self-reaction principle of a foaming agent after inflation, and can play a role in secondary radiation protection and meteorite impact buffering through the application of aerogel materials. The boron-containing compound is boric acid and the polymer foam is polyimide foam. The particle size of the simulated lunar soil is 100 microns. After the inflatable cabin is inflated and unfolded, all the components are uniformly mixed, and foaming is carried out in the cavity of the cabin to form the inflatable structure reinforcing layer 6.
The flexible insulating layer 5 is used for protecting the inner space of the building against extreme high-low temperature alternating environments in the daytime and at night.
The flexible insulation layer 5 is preferably an aerogel-like insulation layer, which is made of a light-weight insulation material.
By using the multilayer flexible composite material and the structure and utilizing lunar soil, multiple protection on space high-energy radiation, lunar surface high and low temperature and micro-fluidic stars can be realized, and a better protection effect is realized at the cost of smaller emission weight.
The utility model provides a composite wall structure can adapt to the folding and the expansion demand in the moon face deployable cabin of living. The inflatable structure reinforcing layer 6 in the wall body is filled by a moonface in-situ foaming process after the inflatable cabin body is completely unfolded, so that the launching weight can be effectively reduced, and the launching cost can be reduced.
After the organic foam material is doped with lunar soil and a boron-containing compound, the combined shielding effect of the high atomic number and low atomic number combined material and the efficient absorption of boron element to neutrons can form better protection effect on cosmic ray high-energy particles and a large amount of secondary neutrons generated by the effect of cosmic ray and lunar surface.

The flexible inner film layer 7 is made of Kevlar composite materials, and an aluminum layer is attached to the surface of the flexible inner film layer 7. After the inflatable structure is unfolded, the stability of the film layer is ensured by a layered aluminum curing mode.
The reinforcing layer 6 of the inflatable structure is prepared by using the simulated lunar soil, the boron-containing compound and the polymer foam material in a ratio of 15:4: 31.
The flexible heat-insulating layer 5 is made of silicon dioxide aerogel.
The flexible protective layer 4 comprises a plurality of layers of high strength textile material. The high-strength fabric is Kevlar fabric or Vectran fabric, and the structural layers are prefabricated on the ground.
