Abstract

[0002] Composite panels integrate the excellent properties of two metals. For example, titanium-steel composite panels possess both the corrosion resistance of titanium and the excellent weldability, formability, and thermal conductivity of steel. Furthermore, titanium-steel composite panels can significantly reduce the amount of precious titanium used, resulting in high economic value and promising application prospects. Currently, they are used in pressure-bearing chemical containers, deep-sea metal pressure-bearing structures, and impact-resistant metal structures. These working environments are difficult to monitor manually in real time, so it is crucial to prevent sudden damage to the composite panels that could lead to structural failure.

[0035] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0036] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.
[0037] In the description of this invention, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features or their sequential relationship.
[0038] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.
[0039] In related technologies, various sensors are typically added to composite panels for remote monitoring. These sensors can monitor the panel's status parameters in real time and provide feedback via electrical signals. Because the status of composite panels in pressurized chemical containers, deep-sea metal pressure structures, and impact-resistant metal structures is difficult to monitor manually in real time, any abnormalities or damage could lead to overall structural failure. Therefore, real-time monitoring of the composite panel's status parameters is necessary to prevent accidents. Currently, commonly used composite panels include titanium-steel composite panels, which are hot-rolled composites of titanium and steel plates. Titanium-steel composite panels possess both the corrosion resistance of titanium and the excellent weldability, formability, and thermal conductivity of steel. However, manufacturing titanium-steel composite panels requires heating both the titanium and steel plates to a high temperature range before hot rolling. If sensors are placed directly between the titanium and steel plates, they are easily damaged and fail after hot rolling. If external sensors are placed after the composite panel is manufactured, the status parameters acquired by the sensors are not accurate enough.
[0040] Reference Figures 1 to 3 As shown, an embodiment of the intelligent composite panel of the present invention includes a first metal plate 100, and a groove 110 is formed on the surface of the first metal plate 100.
[0041] The container 200 has multiple protective chambers 210, each of which is equipped with a fixing mechanism. The container 200 is placed in the groove 110.
[0042] Multiple sensors are placed inside the protective chamber 210 and connected to the container 200 via a fixing mechanism.
[0043] The second metal plate 300 and the container 200 are sandwiched between the second metal plate 300 and the first metal plate 100, and the second metal plate 300 and the first metal plate 100 form a composite plate;
[0044] The melting point and hardness of container 200 are higher than those of the first metal plate 100 and the second metal plate 300.
[0045] The sensor is placed in the protective chamber 210, and one sensor is placed in each protective chamber 210. Different types of sensors can be selected according to the requirements of monitoring status parameters.
[0046] Because the melting point and hardness of container 200 are higher than those of the first metal plate 100 and the second metal plate 300, container 200 can protect the sensor from damage during hot rolling when the sensor is placed in protective chamber 210.
[0047] Taking titanium and steel plates as examples, the first metal plate 100 is a steel plate, and the second metal plate 300 is a titanium plate. A groove 110 is formed on the steel plate for placing the container 200. The container 200 can be made of tungsten metal or a tungsten alloy. Tungsten has a higher melting point and hardness than steel and titanium. During heating and hot rolling of the steel and titanium plates, the container 200 will not soften or deform, maintaining its original shape and protecting the sensor inside the protective chamber 210 from damage.
[0048] It is understandable that multiple protective chambers 210 are arranged in an array, and the outer contour of the groove 110 matches the outer contour of the container 200.
[0049] The purpose of the groove 110 is to provide clearance for the container 200, allowing the container 200 and sensors to be positioned between the first metal plate 100 and the second metal plate 300, ultimately fixed within the composite plate's interlayer. The array arrangement of the protective chambers 210 facilitates the design and manufacture of the container 200 and also makes the creation of the groove 110 easier. The outer contour of the groove 110 matches the contour of the container 200, minimizing the gap between the container 200 and the groove 110 and preventing voids from forming within the composite plate after hot rolling.
[0050] Reference Figure 2 As shown, it can be understood that the container 200 includes multiple arrays of metal tubes 220, and the protective chamber 210 is opened in the metal tubes 220.
[0051] The metal tube 220 can be manufactured using selective laser melting (SLM) technology, preferably using tungsten alloy. SLM is an additive manufacturing technology, or a 3D printing technology. Using SLM to manufacture the metal tube 220 eliminates the need to create a protective chamber 210 by removing material; the protective chamber 210 can be preserved before slicing the model.
[0052] It is understood that the fixing mechanism includes a pressing zone disposed on the metal tube 220, wherein the wall thickness of the pressing zone is less than the wall thickness of the other areas on the metal tube 220.
[0053] The container 200 is composed of multiple arrays of metal tubes 220. Since metal materials can undergo plastic deformation under stress, controlling the reduction of the wall thickness in the extrusion zone of the metal tubes 220 makes it easier to apply pressure to the extrusion zone to change the shape of the metal tubes 220. Specifically, after the sensor is placed in the protective chamber 210 of the metal tubes 220, pressure is applied to the extrusion zone of the metal tubes 220. (Refer to...) Figure 4 and Figure 5 As shown, the metal tube 220 has a thinner wall in the extrusion zone. After being deformed by force, it shrinks inward to clamp the connecting wire of the sensor, or it can directly clamp the sensor to fix the sensor.
[0054] It is understandable that each metal tube 220 has 2 to 5 extrusion zones, and the multiple extrusion zones are arranged along the axial direction of the metal tube 220.
[0055] Multiple compression zones are provided, allowing for the application of external force at appropriate locations based on the sensor size and insertion depth into the protective chamber 210, thereby adjusting the clamping position of the sensor or connecting wires. The compression zones are arranged along the axial direction of the metal tube 220, which is also the axial direction of the protective chamber 210. When the sensor is placed in the protective chamber 210, the insertion depth of the sensor within the protective chamber 210 is adjusted along its axial direction.
[0056] It is understandable that the sensors include temperature sensors and strain sensors.
[0057] Temperature sensors can monitor the temperature changes of the composite plate in real time and generate temperature gradient maps, while strain sensors can monitor the strain of the composite plate and generate strain gradient maps.
[0058] A method for manufacturing a smart composite panel according to an embodiment of the present invention includes the above-described smart composite panel, and the manufacturing is completed through the following steps:
[0059] Step S1: Fabricate container 200 and open multiple protective chambers 210 on container 200;
[0060] Step S2: Select the sensor and fix it inside the protective chamber 210;
[0061] Step S3: A groove 110 is formed on the surface of the first metal plate 100, and the container 200 is placed in the groove 110.
[0062] Step S4: The second metal plate 300 is stacked with the side of the first metal plate 100 with the groove 110, and a composite plate is formed after hot rolling.
[0063] The sensor is placed in the protective chamber 210, and one sensor is placed in each protective chamber 210. Different types of sensors can be selected according to the requirements of monitoring status parameters.
[0064] Because the melting point and hardness of container 200 are higher than those of the first metal plate 100 and the second metal plate 300, container 200 can protect the sensor from damage during hot rolling when the sensor is placed in protective chamber 210.
[0065] Taking titanium and steel plates as examples, the first metal plate 100 is a steel plate, and the second metal plate 300 is a titanium plate. A groove 110 is formed on the steel plate for placing the container 200. The container 200 can be made of tungsten metal or a tungsten alloy. Tungsten has a higher melting point and hardness than steel and titanium. During heating and hot rolling of the steel and titanium plates, the container 200 will not soften or deform, maintaining its original shape and protecting the sensor inside the protective chamber 210 from damage.
[0066] In step S1, tungsten material can be used to fabricate container 200, and selective laser melting (SLM) technology is employed for additive printing. Specifically, a three-dimensional model of container 200 is input, sliced by software, and then a laser is used as an energy source to irradiate a bed of tungsten metal powder to ultimately obtain container 200.
[0067] It is understood that step S4 also includes step S4.1, where the second metal plate 300 and the first metal plate 100 are stacked and placed in a sleeve, and the sleeve is vacuumed; step S4.2, where the first metal plate 100 and the second metal plate 300, together with the sleeve, are heated to a set temperature; and step S4.3, where the first metal plate 100 and the second metal plate 300 are hot rolled until a composite plate is formed.
[0068] A sleeve is used to hold the first metal plate 100 and the second metal plate 300, providing a sealed space for them, and then the sleeve is evacuated. During subsequent heating and hot rolling processes, the first metal plate 100 and the second metal plate 300 are in a vacuum environment, isolated from air, preventing oxidation and retaining their original physical properties. Hot rolling can be performed in a single operation or multiple operations until the composite plate reaches the design thickness.
[0069] It is understood that in step S1, the container 200 is a plurality of metal tubes 220, each metal tube 220 having a compression zone. In step S2, the sensor is placed on the metal tube 220, and then pressure is applied to the compression zone to clamp the sensor’s connecting wire.
[0070] The container 200 is composed of multiple arrays of metal tubes 220. Since metal materials can undergo plastic deformation under stress, the wall thickness of the metal tubes 220 is reduced in the extrusion zone, making it easier to apply pressure to the extrusion zone and change the shape of the metal tubes 220. Specifically, after the sensor is placed in the protective chamber 210 of the metal tubes 220, pressure is applied to the extrusion zone of the metal tubes 220. The wall thickness of the metal tubes 220 is thinner at this point, and after deformation under stress, it contracts inward to clamp the sensor's connecting wires, or it can directly clamp the sensor, thus fixing the sensor in place.
[0071] Furthermore, multiple compression zones can be configured along the axial direction of the metal tube 220. This allows for the application of external force to the compression zones at appropriate locations based on the sensor's size and insertion depth into the protective chamber 210, thereby adjusting the clamping position of the sensor or connecting wire. The compression zones are arranged along the axial direction of the metal tube 220, which is also the axial direction of the protective chamber 210. When the sensor is placed in the protective chamber 210, the insertion depth of the sensor within the protective chamber 210 is adjusted along its axial direction.
[0072] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
