[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

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

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

[0039] Step S100: a shape memory composite material stent 1 is manufactured by a chiral tensile mechanical metamaterial cell, wherein the chiral tensile mechanical metamaterial cell comprises a plurality of wavy ligaments 11 and ring nodes 12 in a ring array, the wavy ligaments 11 can be curled and relaxed through a shaping process, and the ring nodes 12 can be expanded and contracted through a shaping process;

[0040] Step S200: manufacturing a 3D printed ceramic composite plate 2 by 3D printing technology in the space station;

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

[0042] Step S400: installing the 3D printed ceramic composite plate 2 on the shape memory composite material bracket 1, and installing the shape memory composite material bracket 1 on the space station.

[0043] Specifically, the shape memory composite material support 1 is made of a chiral tensile mechanical metamaterial cell, which includes a plurality of annular arrays of wavy ligaments 11 and ring nodes 12. The shape of the chiral tensile mechanical metamaterial cell can be adaptively adjusted as needed, such as Figure 5 As shown, the shape of the chiral auxetic metamaterial cell can be Figure 5 The triangle represented by a can also be Figure 5 The quadrilateral represented by b can also be Figure 5 The pentagon represented by c in the figure. Taking the shape of the chiral tensile metamaterial cell as a quadrilateral as an example, the chiral tensile metamaterial cell includes four annular arrays of wavy ligaments 11, and the ring nodes 12 are connected between the adjacent annular arrays of wavy ligaments 11. When in use, the wavy ligaments 11 can be curled and stretched after the shaping process, and the ring nodes 12 can be expanded and contracted after the 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, the polyimide film 3 is attached to the 3D printed ceramic composite plate 2 through specific mechanical equipment, such as Figure 3 , Figure 4 and Figure 6 As shown, along the direction of the arrow, there are the polyimide film 3, the 3D printed ceramic composite plate 2 and the shape memory composite material bracket 1 in sequence. During installation, a rivet groove can be reserved in the wavy ligament 11 of the shape memory composite material bracket 1. After the wavy ligament 11 is relaxed, the notch of the rivet groove is opened, so that the edge of the 3D printed ceramic composite plate 2 is inserted into the rivet groove. After the wavy ligament 11 is curled, the edge of the 3D printed ceramic composite plate 2 is connected to the rivet groove by static friction, that is, the rivet groove and the edge of the 3D printed ceramic composite plate 2 are riveted together to form a shape as shown in FIG. Figure 6The connection form shown can ensure 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 bracket 1 is not limited to mortise and tenon installation, and other installation methods can also be used; after the polyimide film 3, the 3D printed ceramic composite plate 2 and the shape memory composite material bracket 1 are installed, it can be made into Figure 4 The number of space station protection structures shown can be adjusted according to the needs. When the space station protection structure needs to be installed on the space station, external excitation is applied to the ring node 12. After the circular hole of the ring node 12 is temporarily expanded, a connecting piece such as a latch or a bolt (or a connecting plug provided outside the space station) is used to pass through the circular hole of the ring node 12 and connect to the space station. Then, external excitation is applied to the ring node 12, and the circular hole of the ring node 12 is contracted. The ring node 12 is tightly sleeved on the connecting piece such as the latch or the bolt, thereby installing the shape memory composite material bracket 1 on the space station, and finally being able to form a shape memory composite material bracket 1 on the outside of the space station. Figure 2 Protective housing shown.

[0044] Therefore, in this embodiment, the space station protection structure manufactured by the method includes 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 made of a chiral tensile mechanical metamaterial cell can use the wavy ligaments 11 of the chiral tensile mechanical metamaterial cell to curl and relax through a shaping process, so that the shape memory composite material bracket 1 can change its shape, reduce the space occupied by the shape memory composite material bracket 1, and facilitate carrying; by manufacturing the 3D printed ceramic composite plate 2 by 3D printing technology in the space station, the on-site manufacturing of the 3D printed ceramic composite plate 2 can be realized, and the 3D printed ceramic composite plate 2 can be used 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 bracket 1. When external excitation is applied to the ring node 12 outside the space station, the ring node 12 is easily installed on the space station through a connector by utilizing the process that the ring node 12 first expands and then contracts, thereby facilitating the installation of the shape memory composite material bracket 1 outside the space station, so that the shape memory composite material bracket 1 can be used as a basic support to ensure the stability of the 3D printed ceramic composite plate 2 and the polyimide film 3 on the space station. The shape memory composite material bracket 1, the 3D printed ceramic composite plate 2 and the polyimide film 3 can form a protective shell on the space station to prevent various micrometeorites and space debris from colliding with the space station and causing damage to the space station, thereby improving the impact resistance of the space station.

[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: under external stimulation, heating the temperature of the shape memory material to above the glass transition temperature to prepare a 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 the shape memory material is higher than the glass transition temperature, the shape memory material is in a highly flexible state and is easily deformed under external loads. The specific process is: under external stimulation (such as heating), the temperature of the shape memory material is heated to above the glass transition temperature, and then a load is applied to make it reach the target configuration; the temperature is lowered to the glass transition temperature, so that the shape memory material remains in the temporary configuration and can independently withstand external loads, thereby achieving structural shaping.

[0048] In this way, according to the state of the shape memory material at different temperatures, astronauts can prepare the target configuration by heating the temperature of the shape memory material to above the glass transition temperature, thereby realizing the preparation of the shape of the shape memory material; then lower the temperature of the shape memory material to the glass transition temperature and maintain it in the target configuration. In this way, in the space environment, astronauts can prepare shape memory composite material brackets 1 of different shapes as needed in the space station, thereby improving the convenience of preparing the shape memory composite material bracket 1.

[0049] Optionally, the external excitation form includes but is not limited to thermal drive, magnetic drive, radio frequency drive, microwave drive, optical drive or a combination of drive.

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

[0051] In this way, through external excitation forms including but not limited to thermal drive, magnetic drive, radio frequency drive, microwave drive, optical drive or combined 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 bracket 1 is manufactured on site, and the manufactured shape memory composite material bracket 1 is folded into a compressed shape.

[0053] Specifically, Figure 7 a to b in the figure represents the contraction process of the shape memory composite material support 1, and b to a represents the expansion process of the shape memory composite material support 1. The shape memory composite material support 1 can be a quadrilateral structure after preparation, and the prepared shape memory composite material support 1 can be contracted to a compressed state through the wavy toughness 11.

[0054] In this way, by manufacturing the shape memory composite material bracket 1 on site and folding the manufactured shape memory composite material bracket 1 into a compressed form, the shape memory composite material bracket 1 manufactured on site can be folded into a compressed form, and the volume size is greatly reduced, which is convenient for storage and rocket transportation, and can be driven in space to form an expanded form and installed on an aircraft that needs to be protected.

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

[0056] Specifically, Figure 8 a, b, and c in the figure represent 3D printed ceramic composite panels 2 of different shapes, Fig. 9 a, b, c, and d in the figure represent the shapes of lattice metamaterial cells of different shapes, respectively. The lattice metamaterial cells of the same shape are arranged in an array to form a 3D printed ceramic composite plate 2. Each lattice metamaterial cell can be adjusted in size as needed, and can also be cut in shape according to the shape of the outer wall of the space station.

[0057] In this way, the 3D printed ceramic composite plate 2 is composed of lattice metamaterial unit cells, which facilitates the size adjustment of the 3D printed ceramic composite plate 2 and the cutting of the shape of the 3D printed ceramic composite plate 2.

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

[0059] Specifically, the raw material of the 3D printed ceramic composite panel 2 is composed of resin. After preliminary forming by light curing technology, it is sintered and formed with special heating materials outside the cabin, and finally installed.

[0060] In this way, the material of the 3D printed ceramic composite plate 2 can be resin, and the sintering and forming of the 3D printed ceramic composite plate 2 can be realized outside the cabin, which is convenient for the installation of the 3D printed ceramic composite plate 2 outside the cabin.

[0061] Optionally, manufacturing the 3D printed ceramic composite plate 2 by 3D printing technology in the space station also includes: adding fibers into the 3D printed ceramic by vertical 3D printing technology.

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

[0063] In this way, the physical properties of the 3D printed ceramic composite board 2 can be improved by adding fibers into the 3D printed ceramics through vertical 3D printing technology.

[0064] Optionally, the manufacturing method for the space station protection structure further includes adjusting the raw materials for making the polyimide film 3 to change the emissivity and heat resistance of the polyimide film 3. In this way, by adjusting the raw materials for making the polyimide film 3 to change the emissivity, heat resistance and other properties of the polyimide film 3, the polyimide film 3 can be used in different environments to increase the application range of the polyimide film 3.

[0065] Optionally, combined Fig.10 As shown, the manufacturing method for the space station protection structure also includes:

[0066] 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, they remove the damaged 3D printed ceramic composite plate and install a new 3D printed ceramic composite plate.

[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. Fig.10 abc in the figure represent the damage of 3D printed ceramic composite plate 2 - removal of the damaged 3D printed ceramic composite plate 2 - 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 the camera carried by the external mechanical arm of 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 printed 3D printed ceramic composite plate 2, without the need to print it from the ground and then transport it to space.

[0068] In this way, 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 prepare a polyimide film, then remove the damaged 3D printed ceramic composite plate and install a new 3D printed ceramic composite plate. There is no need to print it from the ground and then transport it to space, which reduces the transportation time of the 3D printed ceramic composite plate 2, thereby improving the convenience of using the 3D printed ceramic composite plate 2.

[0069] Another embodiment of the present invention also provides a protective structure for a space station, which is manufactured by the manufacturing method for a protective structure for a space station as described above, and includes 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 to be installed 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, when in use, the wavy ligament 11 can be curled and relaxed after the shaping process, and the ring node 12 can be expanded and contracted after the shaping process. The 3D printed ceramic composite plate 2 is manufactured in the space station by 3D printing technology. After the 3D printed ceramic composite plate 2 is manufactured, the polyimide film 3 is attached to the 3D printed ceramic composite plate 2 by a specific mechanical device, such as Figure 3 , Figure 4 and Figure 6 As shown, along the arrow direction, there are the polyimide film 3, the 3D printed ceramic composite plate 2 and the shape memory composite material bracket 1 in sequence. Before the 3D printed ceramic composite plate 2 is installed on the shape memory composite material bracket 1, as shown in FIG. Figure 6 As shown, a riveting structure can be reserved on the shape memory composite material bracket 1. Since the wavy ligaments 11 of the shape memory composite material bracket 1 can be expanded, when the 3D printed ceramic composite plate 2 is installed, the wavy ligaments 11 can be expanded so that the 3D printed ceramic composite plate 2 can be inserted into the reserved riveting structure, so that the stability of the 3D printed ceramic composite plate 2 can be ensured after the wavy ligaments 11 are curled; after the polyimide film 3, the 3D printed ceramic composite plate 2 and the shape memory composite material bracket 1 are installed, the following can be made Figure 4The number of space station protection structures shown can be adjusted according to the needs. When the space station protection structure is installed on the space station, external excitation is applied to put the circular hole of the ring node 12 in a temporary expanded state, and a connecting piece such as a latch or a bolt (or a connecting plug outside the space station) is passed through the circular hole of the ring node 12. Then, by applying external excitation to the ring node 12, the circular hole of the ring node 12 shrinks, and the ring node 12 is tightly sleeved on the connecting piece such as the latch or the bolt, so that the shape memory composite material bracket 1 is installed on the space station, and finally a shape memory composite material bracket 1 can be formed outside the space station. Figure 2 Protective housing shown.

[0071] In this way, the shape memory composite material bracket 1 can serve as a basic support to ensure the stability of the 3D printed ceramic composite plate 2 and the polyimide film 3 on the space station. The shape memory composite material bracket 1, the 3D printed ceramic composite plate 2 and the polyimide film 3 can form a protective shell on the space station to prevent various micrometeorites and space debris from colliding with the space station and causing damage to the space station, thereby improving the impact resistance of the space station.

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

[0073] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
