Description

Technical Field

[0001] This invention relates to the field of space station protection technology, and more specifically, to a manufacturing method for a space station protection structure and a space station protection structure. Background Technology

[0002] As a large, complex, and long-duration manned spacecraft, the space station has always been a key project in the aviation field.

[0003] However, due to the high cost of building large space stations, a space station often needs to remain in service for more than a decade. During this time, various micrometeorites and space debris can damage the space station's modules and solar panels. Each extravehicular activity (EVA) is a challenge to the astronauts' abilities and lives, and frequent maintenance can also affect the space station's various functions. Summary of the Invention

[0004] The problem this invention addresses is: how to achieve protection for a space station.

[0005] To address the aforementioned problems, in one aspect, the present invention provides a method for manufacturing a protective structure for a space station, comprising:

[0006] Shape memory composite material scaffolds are fabricated using chiral tensile metamaterial cells, wherein the chiral tensile metamaterial cells include multiple annular arrays of wavy ligaments and circular nodes. The wavy ligaments can be curled and relaxed through a shaping process, and the circular nodes can be expanded and contracted through a shaping process.

[0007] 3D-printed ceramic composite panels were manufactured on the space station using 3D printing technology.

[0008] A polyimide film is attached to the 3D-printed ceramic composite plate;

[0009] The 3D-printed ceramic composite plate is mounted on the shape memory composite material bracket, and the shape memory composite material bracket is used for installation on the space station.

[0010] Optionally, the shaping process includes:

[0011] Under external stimulation, the temperature of the shape memory material is heated to above the glass transition temperature to prepare the target configuration; then the temperature of the shape memory material is lowered to the glass transition temperature to maintain the target configuration.

[0012] Optionally, the external excitation methods include, but are not limited to, thermal drive, magnetic drive, radio frequency drive, microwave drive, optical drive, or a combination of drive.

[0013] Optionally, the shape memory composite material bracket is manufactured on-site, and the manufactured shape memory composite material bracket is folded into a compressed shape.

[0014] Optionally, the 3D printed ceramic composite plate is composed of lattice metamaterial unit cells.

[0015] Optionally, the material of the 3D printed ceramic composite plate may be resin.

[0016] Optionally, the process of manufacturing 3D-printed ceramic composite panels on the space station using 3D printing technology further includes:

[0017] Fibers are incorporated into 3D printed ceramics using vertical 3D printing technology.

[0018] Optionally, the manufacturing method for the protective structure of the space station further includes adjusting the raw materials used to make the polyimide film to change the emissivity and heat resistance of the polyimide film.

[0019] Optionally, the manufacturing method for the protective structure of the space station further includes: when the 3D printed ceramic composite plate is damaged, the astronauts prepare a new 3D printed ceramic composite plate in the space station according to the shape of the damaged 3D printed ceramic composite plate, and after preparing the polyimide film, remove the damaged 3D printed ceramic composite plate and install the new 3D printed ceramic composite plate.

[0020] Compared with existing technologies, the manufacturing method for a space station protective structure of the present invention comprises a shape memory composite material bracket, a 3D-printed ceramic composite plate, and a polyimide film. The shape memory composite material bracket, made from chiral tensile metamaterial cells, can be deformed and expanded through a shaping process using the wavy ligaments of the chiral tensile metamaterial cells, reducing its space occupation and facilitating portability. By manufacturing the 3D-printed ceramic composite plate on the space station using 3D printing technology, the 3D-printed ceramic composite plate 2 can be manufactured on-site, enabling immediate use. The polyimide film is attached to the 3D-printed ceramic composite plate... On the 3D-printed ceramic composite plate, the 3D-printed ceramic composite plate is installed on the wavy ligament of the shape memory composite material bracket. When external excitation is applied to the circular joint point outside the space station, the circular joint point expands and then contracts. The circular joint point is easy to install on the space station through connectors, thus facilitating the installation of the shape memory composite material bracket outside the space station. The shape memory composite material bracket can serve as a basic support, ensuring the stability of the 3D-printed ceramic composite plate and polyimide film on the space station. The shape memory composite material bracket, 3D-printed ceramic composite plate and polyimide film can form a protective shell on the space station, avoiding damage to the space station caused by collisions with various micrometeorites and space debris, and improving the space station's impact resistance.

[0021] On the other hand, the present invention also provides a protective structure for a space station, manufactured by the manufacturing method for a protective structure for a space station as described above, comprising a shape memory composite material bracket, a 3D printed ceramic composite plate and a polyimide film, wherein the shape memory composite material bracket is used for installation on the space station, the 3D printed ceramic composite plate is installed on the shape memory composite material bracket, and the polyimide film is attached to the 3D printed ceramic composite plate.

[0022] The protective structure for the space station has all the beneficial effects of the manufacturing method for the protective structure for the space station, which will not be elaborated here. Attached Figure Description

[0036] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in sequences other than those illustrated or described herein.

[0038] Combination Figures 1 to 6 As shown, the present invention provides a method for manufacturing a protective structure for a space station, comprising:

[0039] Step S100: A shape memory composite material scaffold 1 is fabricated using chiral tensile metamaterial cells. The chiral tensile metamaterial cells include multiple annular arrays of wavy ligaments 11 and circular nodes 12. The wavy ligaments 11 can be curled and relaxed through a shaping process, and the circular nodes 12 can be expanded and contracted through a shaping process.

[0040] Step S200: Manufacture 3D printed ceramic composite plate 2 using 3D printing technology on the space station;

[0041] Step S300: Attach the polyimide film 3 onto the 3D printed ceramic composite plate 2;

[0042] Step S400: Install the 3D printed ceramic composite plate 2 onto the shape memory composite material bracket 1, and use the shape memory composite material bracket 1 to install it on the space station.

[0043] Specifically, the shape memory composite scaffold 1 is fabricated using chiral tensile metamaterial cells. These cells comprise multiple annular arrays of wavy ligaments 11 and circular nodes 12. The shape of these chiral tensile metamaterial cells can be adaptively adjusted as needed, such as... Figure 5 As shown, the shape of the cell element in a chiral tensile metamaterial can be... Figure 5 The triangle represented by 'a' can also be... Figure 5 The quadrilateral represented by b in the middle can also be... Figure 5 The 'c' represents a pentagon, etc. Taking the shape of a quadrilateral as the cell element of a chiral tensile metamaterial as an example, the cell element includes four annular arrays of wavy ligaments 11, with circular nodes 12 connecting adjacent annular arrays of wavy ligaments 11. In use, the wavy ligaments 11 can curl and relax after a shaping process, and the circular nodes 12 can expand and contract after a shaping process. The 3D-printed ceramic composite plate 2 is manufactured in the space station using 3D printing technology. After the 3D-printed ceramic composite plate 2 is manufactured, a polyimide film 3 is attached to the 3D-printed ceramic composite plate 2 using specific mechanical equipment, such as... Figure 3 , Figure 4 and Figure 6 As shown, in the direction of the arrow, the components are, in sequence, a polyimide film 3, a 3D-printed ceramic composite plate 2, and a shape memory composite material support 1. During installation, a riveting groove can be pre-reserved in the wavy ligament 11 of the shape memory composite material support 1. After the wavy ligament 11 relaxes, the groove opens, allowing the edge of the 3D-printed ceramic composite plate 2 to be inserted into the groove. After the wavy ligament 11 curls, the edge of the 3D-printed ceramic composite plate 2 is connected to the groove by static friction, thus riveting the groove and the edge of the 3D-printed ceramic composite plate 2 together, forming a shape memory composite material support 1. Figure 6The connection method shown ensures the stability of the 3D-printed ceramic composite plate 2. Of course, the installation method of the 3D-printed ceramic composite plate 2 and the shape memory composite material support 1 is not limited to mortise and tenon joints; other installation methods are also possible. After installing the polyimide film 3, the 3D-printed ceramic composite plate 2, and the shape memory composite material support 1, a structure like... Figure 4 The space station protective structure shown can be adjusted in number as needed. When the protective structure needs to be installed on the space station, an external excitation is applied to the circular joint 12. After the circular hole of the circular joint 12 temporarily expands, a connector such as a pin or bolt (or a connector plug installed on the outside of the space station) passes through the circular hole of the circular joint 12 and connects to the space station. Then, by applying another external excitation to the circular joint 12, the circular hole of the circular joint 12 contracts, and the circular joint 12 is tightly fitted onto the pin or bolt, thereby installing the shape memory composite material bracket 1 on the space station. Ultimately, it can form a shape memory composite material bracket on the outside of the space station. Figure 2 The protective casing shown.

[0044] Therefore, in this embodiment, the space station protective structure manufactured by this method includes a shape memory composite material support 1, a 3D-printed ceramic composite plate 2, and a polyimide film 3. The shape memory composite material support 1, made of chiral tensile metamaterial cells, can be deformed and expanded by the wavy ligaments 11 of the chiral tensile metamaterial cells through a shaping process, thus reducing the space occupied by the shape memory composite material support 1 and making it easy to carry. By manufacturing the 3D-printed ceramic composite plate 2 on the space station using 3D printing technology, the 3D-printed ceramic composite plate 2 can be manufactured on-site, making it ready to use immediately. By attaching the polyimide film 3 to the 3D-printed ceramic composite plate 2, the 3D-printed... The ceramic composite plate 2 is installed on the wavy ligament 11 of the shape memory composite material support 1. When an external excitation is applied to the circular joint 12 outside the space station, the circular joint 12 expands and then contracts. The circular joint 12 is easy to install on the space station through the connector, thus facilitating the installation of the shape memory composite material support 1 outside the space station. This allows the shape memory composite material support 1 to serve as a basic support, ensuring the stability of the 3D printed ceramic composite plate 2 and polyimide film 3 on the space station. The shape memory composite material support 1, the 3D printed ceramic composite plate 2, and the polyimide film 3 can form a protective shell on the space station, preventing damage to the space station caused by collisions with various micrometeorites and space debris, and improving the space station's impact resistance.

[0045] Based on the above embodiments, the 3D printed ceramic composite plate can be replaced with other lightweight and strong materials; the polyimide film can be replaced with other heat-resistant and highly reflective materials.

[0046] Optionally, the shaping process includes: heating the shape memory material to above the glass transition temperature under external excitation to prepare the target configuration; and then lowering the temperature of the shape memory material to the glass transition temperature to maintain the target configuration.

[0047] Specifically, when the temperature of a shape memory material is above its glass transition temperature, the material is in a highly flexible state and easily deforms under external loads. The specific process involves heating the shape memory material above its glass transition temperature under external excitation (such as heating), then applying a load to achieve the target configuration; finally, lowering the temperature to the glass transition temperature allows the material to maintain this temporary configuration and independently withstand external loads, thus achieving structural shaping.

[0048] Thus, based on the state of shape memory materials at different temperatures, astronauts can heat the shape memory materials to above the glass transition temperature to prepare the target configuration and realize the preparation of the shape memory material shape; then lower the temperature of the shape memory materials to the glass transition temperature to maintain the target configuration. In this way, in the space environment, astronauts can prepare shape memory composite material scaffolds 1 of different shapes as needed in the space station, improving the convenience of preparing shape memory composite material scaffolds 1.

[0049] Optionally, the external excitation methods include, but are not limited to, thermal drive, magnetic drive, radio frequency drive, microwave drive, optical drive, or a combination of these.

[0050] Specifically, if thermal drive is used, a resistive thin-film heater is attached to the lower surface of the thermal protection structure; if electric drive is used, the shape memory composite material should be doped with one or more of the following conductive reinforcing phases: single-walled or multi-walled carbon nanotubes, graphene, carbon black, carbon nanopaper, carbon nanofibers, chopped carbon fibers, continuous carbon fibers, or mixed particles, and an external power supply should be connected to the doped phases to form a circuit; if microwave drive is used, the shape memory composite material should be doped with nanoparticles such as carbon nanotubes, graphene oxide, and silicon carbide; if radio frequency drive is used, the shape memory composite material should be doped with radio frequency sensitive particles such as carbon nanotubes; if optical drive is used, optical fibers or other materials should be embedded in the shape memory composite material; if combined drive is used, the reinforcing phases doped in the shape memory composite material should include two or more of the above combinations.

[0051] Thus, by using external excitation methods including but not limited to thermal drive, magnetic drive, radio frequency drive, microwave drive, optical drive, or a combination of drive, a variety of external excitation methods are provided to improve the forming efficiency of the shape memory composite material bracket 1.

[0052] Optionally, combined Figure 7As shown, the shape memory composite material support 1 is manufactured on-site, and the manufactured shape memory composite material support 1 is folded into a compressed shape.

[0053] Specifically, Figure 7 In the diagram, a to b represents the shrinking process of the shape memory composite scaffold 1, while b to a represents the expansion process of the shape memory composite scaffold 1. After preparation, the shape memory composite scaffold 1 can be a quadrilateral structure. The prepared shape memory composite scaffold 1 can be folded into a compressed shape by using a wave-shaped ligament 11.

[0054] Thus, the shape memory composite material bracket 1 is manufactured on-site, and the manufactured shape memory composite material bracket 1 is folded into a compressed form. The shape memory composite material bracket 1 manufactured on-site can be folded into a compressed form, greatly reducing its size, which is convenient for storage and rocket transportation. It can also be driven into an unfolded form in space and installed on a spacecraft that needs protection.

[0055] Optionally, combined Figure 8 and Figure 9 As shown, the 3D printed ceramic composite plate 2 is composed of lattice metamaterial unit cells.

[0056] Specifically, Figure 8 In the text, a, b, and c represent 3D printed ceramic composite plates of different shapes. Figure 9 In the diagram, a, b, c, and d represent the shapes of different lattice metamaterial unit cells. Lattice metamaterial unit cells of the same shape are arrayed and sorted to form a 3D-printed ceramic composite plate. Each lattice metamaterial unit cell can be adjusted in size as needed, or it can be cut to fit the shape of the outer wall of the space station.

[0057] Thus, since the 3D printed ceramic composite plate 2 is composed of lattice metamaterial unit cells, it is convenient to adjust the size of the 3D printed ceramic composite plate 2 and also convenient to cut the shape of the 3D printed ceramic composite plate 2.

[0058] Optionally, the material of the 3D printed ceramic composite plate 2 can be resin.

[0059] Specifically, the raw material of the 3D printed ceramic composite plate 2 is composed of resin. After being initially shaped by photopolymerization technology, it is sintered outside the chamber using special heating materials and finally installed.

[0060] Thus, the material of the 3D printed ceramic composite plate 2 can be resin, which enables the 3D printed ceramic composite plate 2 to be sintered outside the cabin, facilitating the external installation of the 3D printed ceramic composite plate 2.

[0061] Optionally, manufacturing 3D-printed ceramic composite panels 2 on the space station using 3D printing technology also includes: incorporating fibers into the 3D-printed ceramics using vertical 3D printing technology.

[0062] Specifically, vertical 3D printing technology can be used to directly incorporate fibers into 3D printed ceramics to improve the composite effect and enhance their physical properties. For example, carbon fiber can reduce the weight of 3D printed ceramics.

[0063] Thus, by incorporating fibers into 3D printed ceramics using vertical 3D printing technology, the physical properties of 3D printed ceramic composite plates can be improved.

[0064] Optionally, the manufacturing method for the protective structure of the space station also includes adjusting the raw materials used to make the polyimide film 3 to change its emissivity and heat resistance. Thus, by adjusting the raw materials used to make the polyimide film 3 to change its emissivity, heat resistance, and other properties, the polyimide film 3 can be applied to different environments, thereby improving its applicability.

[0065] Optionally, combined Figure 10 As shown, the manufacturing method for the protective structure of the space station also includes:

[0066] When a 3D-printed ceramic composite plate is damaged, astronauts prepare a new 3D-printed ceramic composite plate in the space station according to the shape of the damaged plate. After preparing a polyimide film, the damaged plate is removed and the new plate is installed.

[0067] Specifically, the shape of the 3D-printed ceramic composite plate 2 can be cut, such as... Figure 8 As shown, the 3D printed ceramic composite plate 2 is cut into different shapes as needed. Figure 10 The a, b, and c in the diagram represent, in order, the damage to the 3D-printed ceramic composite plate 2, the removal of the damaged 3D-printed ceramic composite plate 2, and the installation of a newly prepared 3D-printed ceramic composite plate 2. Specifically, when the 3D-printed ceramic composite plate 2 is damaged, it can be detected in time by a camera carried by the robotic arm outside the space station. After the astronauts print the 3D-printed ceramic composite plate 2 according to the corresponding size and shape and prepare the polyimide film 3, they first remove the damaged 3D-printed ceramic composite plate 2 and then install the newly printed 3D-printed ceramic composite plate 2, eliminating the need to print it from the ground and transport it to space.

[0068] Thus, when the 3D-printed ceramic composite plate is damaged, astronauts can prepare a new 3D-printed ceramic composite plate and a polyimide film in the space station according to the shape of the damaged 3D-printed ceramic composite plate. After that, the damaged 3D-printed ceramic composite plate can be removed and the new 3D-printed ceramic composite plate can be installed. There is no need to print it from the ground and transport it to space, which reduces the transportation time of the 3D-printed ceramic composite plate 2 and improves the ease of use of the 3D-printed ceramic composite plate 2.

[0069] Another embodiment of the present invention provides a protective structure for a space station, manufactured by the manufacturing method for a protective structure for a space station as described above, comprising a shape memory composite material bracket 1, a 3D printed ceramic composite plate 2, and a polyimide film 3. The shape memory composite material bracket 1 is used for installation on the space station, the 3D printed ceramic composite plate 2 is installed on the shape memory composite material bracket 1, and the polyimide film 3 is attached to the 3D printed ceramic composite plate 2.

[0070] Specifically, in use, the wavy ligament 11 can curl and relax after a shaping process, and the rounded node 12 can expand and contract after a shaping process. The 3D-printed ceramic composite plate 2 is manufactured using 3D printing technology within the space station. After the 3D-printed ceramic composite plate 2 is manufactured, a polyimide film 3 is attached to it using specific mechanical equipment, such as... Figure 3 , Figure 4 and Figure 6 As shown, in the direction of the arrow, the components are, in order, polyimide film 3, 3D printed ceramic composite plate 2, and shape memory composite material support 1. Before installing the 3D printed ceramic composite plate 2 onto the shape memory composite material support 1, as follows... Figure 6 As shown, a riveting structure can be pre-reserved on the shape memory composite material support 1. Because the wavy ligaments 11 of the shape memory composite material support 1 can relax, when installing the 3D printed ceramic composite plate 2, the 3D printed ceramic composite plate 2 can be inserted into the pre-reserved riveting structure through the relaxation process of the wavy ligaments 11, ensuring the stability of the 3D printed ceramic composite plate 2 after the wavy ligaments 11 curl. After installing the polyimide film 3, the 3D printed ceramic composite plate 2, and the shape memory composite material support 1, a structure like... Figure 4The space station protective structure shown can be adjusted in number as needed. When installing this protective structure on the space station, an external excitation is applied, causing the circular hole of the circular link 12 to temporarily expand. A pin or bolt (or an external connector) is passed through the circular hole of the circular link 12. Then, by applying another external excitation to the circular link 12, the circular hole contracts, and the circular link 12 tightly fits onto the pin or bolt, thus installing the shape memory composite material bracket 1 on the space station. Ultimately, this creates a shape memory composite material bracket on the exterior of the space station. Figure 2 The protective casing shown.

[0071] Thus, the shape memory composite material support 1 can serve as a basic support to ensure the stability of the 3D printed ceramic composite plate 2 and polyimide film 3 on the space station. The shape memory composite material support 1, 3D printed ceramic composite plate 2 and polyimide film 3 can form a protective shell on the space station to prevent damage to the space station caused by collisions with various micrometeorites and space debris, thereby improving the space station's impact resistance.

[0072] The protective structure for the space station has all the beneficial effects of the manufacturing method for the protective structure for the space station, which will not be elaborated here.

[0073] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
