Description

Technical Field

[0001] This invention belongs to the field of materials processing technology, specifically relating to the structure and manufacturing method of a non-material reinforced wall panel component. Background Technology

[0002] The design and manufacturing concepts of lightweight, long-life, and low-cost vehicles place higher demands on traditional aircraft manufacturing forming technologies and structural designs. New component structures are evolving towards larger size, integration, and functionality, while also requiring higher forming precision. Compared to early metal panel components, fiber-reinforced resin-based composite panels are widely used in aircraft structural component manufacturing due to their lightweight and design flexibility. Traditionally, fiber-reinforced resin-based composite stiffener panels are formed by stacking fiber prepregs in a tooling mold, covering them with a vacuum bag, and then curing them in an autoclave to complete the main structure manufacturing. Both the panels and stiffeners are made of composite materials. However, during the curing process, the resin matrix in the stiffener panel undergoes changes from viscous flow to rubber and glass states. Under high temperature and pressure, this can easily cause the stiffeners to shift position, reducing the overall forming precision of the stiffened panel. To address the issue of stiffener misalignment during the forming of stiffened panels, traditional methods employ stiffener positioning fixtures for fixation, completing the stiffener positioning before curing in the autoclave. This increases the complexity and manufacturing difficulty of the stiffener panel forming process. Furthermore, stiffener misalignment still frequently occurs when the fixture is clamped and is affected by environmental factors, becoming a bottleneck for product quality improvement. In addition, the stiffener positioning fixtures also lead to higher equipment costs, longer process cycles, and higher overall process costs. Summary of the Invention

[0003] In view of the problems existing in the forming technology of reinforcing ribbed panels, the purpose of this invention is to provide a structure and manufacturing method for a dissimilar material reinforcing ribbed panel component, which is achieved by using a fiber-reinforced resin matrix composite panel combined with metal material reinforcing ribs. This invention uses metal materials to replace the traditional fiber composite material reinforcing ribs. The dissimilar material panel, consisting of a fiber-reinforced resin matrix composite panel and a metal reinforcing rib thin sheet web, is manufactured using an autoclave curing process, combined with a welding connection process using vertical reinforcing ribs to achieve an integrally reinforced panel component. This invention broadens the adjustment range of the relative position of the vertical ribs and the panel, effectively solves the problem of reinforcing rib misalignment, improves the manufacturing accuracy and mechanical load-bearing capacity of the reinforcing ribbed panel, reduces the manufacturing process difficulty, manufacturing and tooling costs, and the weight of the reinforcing ribbed panel, achieving high-quality, low-cost manufacturing of the reinforcing ribbed panel component.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows:

[0005] The structure of the dissimilar material reinforced wall panel component includes a fiber-reinforced resin matrix composite matrix, a metal T-joint web, and metal reinforcing ribs. The fiber-reinforced resin matrix composite matrix and the metal T-joint web are bonded together by one-time curing or two-time bonding to form a dissimilar material wall panel structure, while the metal T-joint web and the metal reinforcing ribs are connected by a connection process to form a T-shaped, I-shaped, or L-shaped reinforcing structure.

[0006] The reinforcing fibers in the fiber-reinforced resin-based composite material are continuous fibers or continuous fiber fabrics. The fiber material can be inorganic or organic fibers such as carbon fiber, glass fiber, aramid fiber, and basalt fiber. The resin matrix can be a polymer material such as epoxy resin, bismaleimide resin, cyanate ester resin, phenolic resin, vinyl ester resin, polyurethane resin, and unsaturated polyester resin.

[0007] The metal material for the T-shaped, I-shaped, or L-shaped reinforcing structure can be lightweight, high-strength materials such as aluminum alloy or titanium alloy;

[0008] The aforementioned metal T-shaped, I-shaped, or L-shaped reinforcing structure is composed of a metal T-shaped joint web and metal material reinforcing ribs. The composition of the dissimilar material reinforcing rib wall panel structure is as follows: the web of the T-shaped, I-shaped, or L-shaped reinforcing structure and the fiber-reinforced resin matrix composite material matrix are first integrally formed by using an autoclave or other equipment that can simultaneously apply pressure and high temperature, and then connected to the reinforcing rib structure to form the final dissimilar material reinforcing wall panel.

[0009] The T-shaped, I-shaped or L-shaped reinforcing structure web is a long strip of thin metal plate or sheet, or a metal structural component with serrated or needle-shaped bends, which can improve the connection with the fiber-reinforced composite wall panel while ensuring the integrity of the fiber wall panel.

[0010] The reinforcing rib structure is a flat straight rib or has unidirectional or bidirectional bent edges, or other structural forms that enhance the rigidity of the reinforcing rib.

[0011] The connection between the dissimilar material wall panel and the reinforcing rib structure adopts either a single-sided heat source corner connection or a double-sided heat source corner connection for the vertical rib.

[0012] The preferred heat source is a high-energy beam heat source such as a laser or electron beam. During the connection process, welding wire of the same metal material as the T-shaped, I-shaped or L-shaped reinforcing structure should also be inserted. Alternatively, low-heat-input arc welding connection processes such as cold metal transition welding can be selected.

[0013] The present invention also provides a forming process for realizing the above-mentioned dissimilar material reinforced wall panel, characterized in that:

[0014] The dissimilar material reinforced wall panel structure is a dissimilar material wall panel with fiber-reinforced resin matrix composite material as the matrix and embedded metal T-shaped, I-shaped or L-shaped reinforcement structure, which is cured and formed by autoclave or other equipment that can simultaneously apply pressure and high temperature.

[0015] The aforementioned metal T-shaped, I-shaped, or L-shaped reinforcing structure consists of a web and reinforcing ribs;

[0016] The forming method of the dissimilar material reinforced wall panel is as follows: the web of the T-shaped, I-shaped or L-shaped reinforcing structure and the fiber-reinforced resin matrix composite material are first integrally formed by using an autoclave or other equipment that can simultaneously apply pressure and high temperature in the form of inlay or surface covering bonding. Then, it is connected with the reinforcing rib structure to form the final dissimilar material reinforced wall panel.

[0017] The T-shaped, I-shaped, or L-shaped reinforcing structure web is a long strip of thin metal plate or sheet, or a metal structural component with serrated or needle-shaped bends, which can improve the connection with the fiber-reinforced composite wall panel and ensure the integrity of the fiber wall panel.

[0018] The reinforcing rib structure is a flat straight rib or has unidirectional or bidirectional bent edges, or other structural forms that enhance the rigidity of the reinforcing rib.

[0019] The connection between the dissimilar material wall panel and the reinforcing rib structure adopts either a single-sided heat source corner connection or a double-sided heat source corner connection for the vertical rib.

[0020] The preferred heat source is a high-energy beam heat source such as a laser or electron beam. During the connection process, welding wire of the same metal material as the T-shaped, I-shaped, or L-shaped reinforcing structure should also be inserted.

[0021] A method for manufacturing dissimilar material reinforced wall panel components includes the following steps:

[0022] 1. Fabrication of web plates for T-shaped, I-shaped, or L-shaped joints

[0023] 1.1 Determine the shape of the web. The web can be a long strip of thin metal plate or sheet. To improve the bonding force when the web is connected to the fiber-reinforced composite wall panel, the web can also be a thin-walled component with features such as serrated edges to enhance bonding force. Its length should be consistent with the length of the fiber-reinforced composite wall panel to be installed, and its width is approximately 10mm to 40mm.

[0024] 1.2 Fabrication of web shape: Metal flat strips or thin sheets can be fabricated using metal cutting technology, while thin-walled components with characteristic structures need to be fabricated by sheet metal forming process after the blank is pre-placed using metal cutting process.

[0025] 2. Fabrication of dissimilar material wall panels

[0026] 2.1. Based on the product shape and structure requirements, design and determine the geometric shape of the fiber composite wall panel and its size. Then, design and determine the selection of continuous fiber prepreg or fabric and parameters such as layup direction, number of layups, and layup thickness.

[0027] 2.2 Tooling and mold preparation: Based on the product shape and structure requirements and the technical requirements of the dissimilar material wall panel process, design and determine the tooling and mold structure and function for preparing fiber composite wall panels, and prepare the tooling and mold required for fiber composite wall panels.

[0028] 2.3 Preparation of dissimilar material wall panels: The raw materials for fiber composite wall panels, such as continuous fiber prepreg or fabric, are precisely positioned and laid on the mold surface according to the determined layup parameters. Then, the metal web is laid on the prepreg or fabric according to the positioning requirements. Finally, the dissimilar material wall panels are co-cured and formed according to the technical requirements of autoclave molding or liquid molding process. Alternatively, the above-mentioned fiber composite wall panels without metal webs can be cured and formed first, and then the metal webs can be connected to the fiber composite wall panels by secondary bonding.

[0029] 3. Fabrication of reinforcing rib structure

[0030] 3.1 The design determines the shape of the reinforcing rib. The reinforcing rib can be a flat straight rib, or a unidirectional or bidirectional bent edge, or other structural forms that enhance the rigidity of the reinforcing rib. The specific shape is determined based on the stress state of the component. When the stress state is simple and the stress level is low, a flat straight rib structure is selected; when the stress state is complex or the stress level is high, a structural form that enhances the rigidity of the reinforcing rib is selected, such as a bent edge vertical rib, a reinforcing rib with a bent edge, etc., and its length should be consistent with the length of the web at the installation location.

[0031] 3.2 Fabrication of reinforcing ribs: Flat straight ribs can be fabricated using metal cutting technology, while for reinforcing ribs with rigid reinforcement features, it is necessary to use metal cutting technology to pre-place the blank and then fabricate it using sheet metal forming technology.

[0032] 4. Connection between dissimilar material wall panels and reinforcing rib structures

[0033] Based on the heat source distribution pattern used in T-shaped, I-shaped, or L-shaped joint connections, they can be divided into single-sided heat source filler corner joint connection process and double-sided heat source filler corner joint connection process.

[0034] 4.1 Single-sided heat source filler wire corner connection of vertical reinforcement

[0035] 4.11. For T-shaped, I-shaped or L-shaped joint repair, the reinforced ribs after pickling and the web plate after mechanical grinding shall be repaired by mechanical scraping. The edges of the reinforced ribs should be kept after scraping and repair, and no chamfers should be made.

[0036] 4.12 Step 2: Adjusting the attitude of the heat source. The welding attitude of the heat source is adjusted and the welding path is taught by adjusting the spatial attitude of the robotic arm with the welding heat source installed. After aligning the extension line of the heat source axis with the contact line of the corner joint, it is adjusted upward by 0.5mm.

[0037] 4.13. Setting connection parameters and forming connection: Adjust the heat source parameters and control the connection molten pool so that when the heat source melts the vertical ribs and web on one side, the back of the molten pool simultaneously forms the excess height to form a joint. In addition, in order to compensate the metal on the heat source side and suppress the formation of undercut, welding wire of the same material as the T-shaped, I-shaped or L-shaped joint should be fed into the heat source side in real time to achieve the compensation of the metal on the heat source side and finally complete the forming of the connection joint.

[0038] 4.2 Double-sided heat source filler angle connection of vertical reinforcement

[0039] 4.21. For T-shaped, I-shaped or L-shaped joint repair, the reinforced ribs after pickling and the web plate after mechanical grinding shall be repaired by mechanical scraping. The edges of the reinforced ribs should be kept after scraping and repair, and no chamfers should be made.

[0040] 4.22. Heat source attitude adjustment: The welding attitude of the heat source and the welding path are adjusted by adjusting the spatial attitude of the robotic arm equipped with the welding heat source. After aligning the extension lines of the heat source axes on both sides with the contact line of the corner joint, adjust upward by 0.5mm. During path teaching, the heat sources on both sides should be in a spatial out-of-position mode along the heat source travel path, with an out-of-position distance of about 10mm to 20mm. This avoids oxidation of the molten pool caused by the inert gas acting towards each other at the connection starting point due to synchronous and co-position.

[0041] 4.23. Setting connection parameters and forming the connection: Adjust the heat source parameters to achieve simultaneous melting of the vertical ribs and web to form a molten pool. In order to compensate for the metal loss on the heat source side and suppress the formation of undercut, welding wire should be fed into the heat source side in real time to achieve metal compensation on the heat source side and finally complete the forming of the connection joint.

[0042] Compared with the prior art, the present invention has the following advantages:

[0043] Compared to fiber-reinforced composite reinforced wall panels, dissimilar material reinforced wall panels fully utilize the flexibility and adaptability of the split structure, improving the relative positional adjustability of the vertical ribs and the dissimilar material wall panels. This enhances the positional accuracy of the reinforcing ribs in dissimilar material reinforced wall panels and eliminates the manufacturing and associated costs of complex positioning fixtures required for fiber-reinforced composite reinforced wall panels. Furthermore, the preparation process of dissimilar material reinforced wall panels is simpler and more efficient, significantly shortening the manufacturing cycle and reducing manufacturing costs compared to the manufacturing process of fiber-reinforced composite reinforced wall panels.

[0044] The dissimilar material wall panels and reinforcing ribs are connected by a high-energy beam heat source, which can achieve high-speed connection of T-shaped, I-shaped or L-shaped joints while controlling the heat accumulation at the connection point to be lower than the thermal damage tolerance of the fiber-reinforced composite material, thus suppressing material failure caused by overheating of the resin matrix in the fiber-reinforced composite material.

[0045] The heterogeneous material reinforced wall panel also makes full use of the high strength and high elastic modulus of metal materials. Compared with fiber-reinforced resin matrix composites, the volume of the reinforcing part is significantly reduced and the weight is significantly reduced, thus realizing the weight reduction of the reinforced wall panel component.

Detailed Implementation

[0059] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings.

[0060] like Figure 1 As shown, the fiber-reinforced resin matrix composite stiffener wall panel is manufactured using processes such as fiber laying, tape laying, bonding, and autoclave curing. Due to the fluidity of the resin matrix, the stiffeners of the manufactured components often shift under pressure, making it difficult to guarantee the dimensional accuracy of the components. At the same time, since the stiffeners and wall panel are integrally formed, positioning tooling is required, which increases the process difficulty and manufacturing cost.

[0061] To address the aforementioned issue of stiffener misalignment, this invention provides a structure and manufacturing method for a dissimilar material stiffened panel. It replaces the stiffener portion of the fiber-reinforced resin-based composite material with a metal T-shaped structure and employs an appropriate connection process to ultimately form the metal stiffener structure. This enhances the flexibility and adaptability of component manufacturing, broadens the tolerance range of the component, and improves the manufacturing precision of the component.

[0062] like Figure 2 As shown, the structure of the dissimilar material reinforced wall panel is achieved by replacing the metal material in the reinforcing part of the fiber-reinforced resin matrix composite wall panel with the metal material, completing the curing and forming of the fiber-reinforced resin matrix composite matrix 1, and manufacturing the dissimilar material wall panel 3 with the metal T-shaped joint web plate 2, and completing the welding connection with the metal metal reinforcing rib 4 by the connection process.

[0063] The reinforcing fibers in fiber-reinforced resin-based composites can be continuous fibers or continuous fiber fabrics, and the fiber material can be inorganic or organic fibers such as carbon fiber, glass fiber, aramid fiber, and basalt fiber. The resin matrix can be a polymer material such as epoxy resin, bismaleimide resin, cyanate ester resin, phenolic resin, vinyl ester resin, polyurethane resin, and unsaturated polyester resin. The material of the metal T-joint can be a lightweight, high-strength material such as aluminum alloy or titanium alloy.

[0064] The web of a T-joint can take many forms, including a long, thin metal plate or sheet, a metal component with serrated or needle-like bends, or a metal component that can improve the connection with fiber-reinforced composite wall panels. Figure 3 shows several typical web structures: Figure a shows a long, thin metal plate; Figure b shows a web structure with bends, the size of which is determined by the bonding force with the fiber-reinforced resin composite wall panel; Figure c shows a structure with serrated bends, the characteristic size of which is determined by the bonding force with the fiber-reinforced resin composite wall panel.

[0065] The shape of the T-shaped joint reinforcing rib can take many forms, such as a flat straight rib, a unidirectional bent edge, or other structural forms that enhance the rigidity of the reinforcing rib. Figure 4 shows several typical reinforcing rib structures: (a) a straight rib; (b) a reinforcing rib with a bent edge.

[0066] The connection process for T-joints can choose high-energy beam connection technologies such as laser and electron beam, or low-heat-input connection technologies such as cold metal transition welding. There are two main connection process principles for heat sources. Figure 5 shows the corresponding connection process diagrams: (a) single-sided heat source filler corner joint connection for vertical ribs; (b) double-sided heat source filler corner joint connection for vertical ribs. According to different connection process methods, the connection principles corresponding to each process method are shown in Figure 6. Among them, (a) is a schematic diagram of the single-sided heat source filler corner joint connection principle for vertical ribs. The connection principle is that when the single-sided heat source 5 melts the vertical rib and web, the back of the single-sided weld pool 6 simultaneously forms the excess height to form a joint; (b) is a double-sided heat source filler corner joint connection for vertical ribs. The connection principle is that the high-energy beam heat sources 7 on both sides of the vertical rib heat and melt the vertical rib and web on their respective sides, and simultaneously melt them to form their respective weld pools 8. Then, the solidified weld pools overlap to complete the connection.

[0067] The present invention is illustrated below with classic embodiments:

[0068] Example 1. Manufacturing of a component based on a dissimilar material stiffener panel made of aluminum alloy:

[0069] use Figure 2The given structural form involves prefabricating a fiber-reinforced resin matrix matrix 1 using wire laying, followed by embedding a 2mm thick aluminum alloy T-shaped joint web 2 onto the surface of the matrix 1. This is then cured in an autoclave to form a dissimilar material panel 3. A 1.5mm thick aluminum alloy reinforcing rib 4 is fabricated using sheet metal forming combined with machining. The aluminum alloy T-shaped joint reinforcing rib and web are fitted and positioned according to required dimensions. The final T-shaped joint is formed using a single-sided heat source filler wire corner joint connection process. Welding parameters include a laser power of 2000W, a welding speed of 3000mm / min, a defocusing amount of 1mm, a welding wire diameter of 1.2mm, and a wire feed speed of 3000mm / min. Results show that the joint has good internal and external quality, with the positional accuracy deviation of the reinforcing rib less than 0.5mm, meeting the usage requirements.

[0070] Example 2. Manufacturing of components with dissimilar material stiffeners based on titanium alloy:

[0071] use Figure 2 The given structural form involves prefabricating a fiber-reinforced resin matrix matrix 1 using tape laying, then embedding a 2mm thick titanium alloy T-shaped joint web 2 onto the surface of the matrix 1, followed by curing in an autoclave to form a dissimilar material panel 3. A 1.5mm thick titanium alloy metal reinforcing rib 4 is fabricated using sheet metal forming combined with machining. The titanium alloy T-shaped joint reinforcing rib and web are fitted and positioned according to the required dimensions and locations. The final T-shaped joint is formed using a double-sided heat source filler wire corner joint connection process. Due to the extremely reactive high-temperature chemical properties of titanium alloy, a coaxial inert gas, coaxial with the laser incident axis, is used to protect the high-temperature molten pool during welding. Furthermore, during welding path teaching, the heat sources on both sides of the vertical rib should maintain a 10mm gap along the welding direction to prevent oxidation of the molten pool at the welding start point. The welding parameters selected were: laser power 2000W, welding speed 3000mm / min, defocusing amount 1mm, welding wire diameter 1.2mm, wire feed speed 3000mm / min, and coaxial inert gas flow rate 10L / min. Results showed that the joint formed good internal and external quality, and the positional accuracy deviation of the vertical ribs was less than 0.5mm, meeting the usage requirements.
