Description

Technical Field

[0001] This invention relates to the field of composite material manufacturing technology, and in particular to a process cover structure for a co-cured fuselage panel and its manufacturing method. Background Technology

[0002] In the manufacturing process of composite co-cured wall panels, the skin is often formed using a male mold. To ensure the quality of the skin forming, a process cover plate is needed to assist in the forming of the skin surface, ensuring that the skin fits the male mold surface and the forming accuracy meets the design requirements. The process cover plate has become a key auxiliary tooling component in the forming process of such composite material components, and is widely used, especially in the manufacturing of high-end composite material structures in aerospace and other fields.

[0003] However, in actual production, due to the structural complexity and dimensional specifications of the composite co-cured wall panels, there are significant technical and cost drawbacks to using an integral process cover plate design and manufacturing. On the one hand, the manufacturing cost of integral process cover plates is high, and their large size and strong structural rigidity significantly increase the difficulty of their application. Specifically, this manifests as inconvenience in handling and assembly during operation, and the difficulty in matching the positioning surfaces of the cover plate with the male mold and skin, which can easily lead to positioning deviations and thus affect the skin forming accuracy. On the other hand, for some composite co-cured wall panel parts with special shapes and structures, due to factors such as their structural contours and curvature variations, integral process cover plates cannot be used for auxiliary molding. The process cover plates must be designed, manufactured, and applied in sections to adapt to the special structural requirements of the parts.

[0004] Currently, conventional modular composite material process covers require each individual cover to undergo prepreg application, curing, and subsequent machining processes using its own independent molding fixtures. The manufacturing processes of each cover are independent of each other. In practical applications, these cover sections need to be assembled for skin-assisted molding. Existing assembly methods often use locating pin holes to connect the cover sections, but this method has significant shortcomings: dimensional deviations and surface errors are easily generated during the independent manufacturing of each cover section, and the precision of the fit between the locating pin holes and the locating pins is difficult to control. This leads to difficulties in positioning and aligning the cover sections during assembly, making it difficult to place them quickly and accurately. Furthermore, it prevents good adhesion between the cover sections and the skin's surface, affecting the uniformity of pressure application and molding quality of the skin. This can easily result in internal defects such as angular protrusions, resin overload, and delamination, failing to meet the high-precision manufacturing requirements of composite co-cured wall panels.

[0005] In summary, existing process cover plates for composite co-cured wall panel molding, whether integral or conventional segmented structures, suffer from high manufacturing costs, difficult process application, and poor positioning and bonding effects. These issues restrict the manufacturing efficiency and molding quality of composite co-cured wall panels. There is an urgent need for a process cover plate structure and manufacturing method for co-cured fuselage wall panels to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a process cover structure for co-cured fuselage panels and its manufacturing method, so as to solve the technical problems existing in the prior art, such as high manufacturing cost, difficulty in process application, and poor positioning and bonding effect.

[0007] Based on the above concept, the technical solution adopted by this invention is as follows: On the one hand, a process cover structure for co-curing body wall panel is provided, including at least two cover bodies and connecting components. The cover body includes connecting fasteners embedded at both ends of the cover body, and the connecting fasteners at least partially protrude from the cover body. The connecting assembly includes a first connector, a second connector, and a locking member. The first connector is connected to the connecting fastener at one end of the cover plate body, the second connector is connected to the connecting fastener at the other end of the cover plate body, and the locking member can connect and fix the first connector and the second connector.

[0008] Preferably, both the first connector and the second connector include a connector base and an adapter. The connector base is used to connect with the corresponding connector fixing member. The connector fixing member has a locking block at one end away from the cover plate body. The connector base has a locking groove that cooperates with the locking block. The adapter is used to connect with the locking member.

[0009] Preferably, the transition portion of one of the first connector and the second connector is configured as a protrusion, and the transition portion of the other of the first connector and the second connector is configured as a groove corresponding to the protrusion, and the locking member can pass through one side wall of the groove, the protrusion and the other side wall of the groove in sequence.

[0010] Preferably, the locking element includes a bolt and a nut, the bolt being able to pass through the first connector and the second connector and be locked with the nut.

[0011] Preferably, the connecting fastener includes a pre-embedded part and a connecting part. The pre-embedded part is embedded inside the cover plate body, and the connecting part protrudes from the cover plate body. The connecting part is provided with a locking block for connecting with the first connecting member or the second connecting member.

[0012] Preferably, the end of the pre-embedded part away from the connecting part is provided with an anti-detachment structure.

[0013] Preferably, the end of the cover plate body is provided with a plurality of connecting fasteners along a first direction, and the plurality of connecting components respectively connect and fix two corresponding connecting fasteners, wherein the first direction is perpendicular to the connecting direction of the cover plate body.

[0014] Secondly, a method for manufacturing a process cover structure for a co-cured fuselage panel is provided, applicable to the aforementioned process cover structure, including: Place the cover plate body in the preset position; Connect the first connector and the second connector to the connecting fastener respectively; The locking element connects the first connector and the second connector until the cover plate body is connected end to end.

[0015] Preferably, before placing the cover plate body in the preset position, the method further includes laying the cover plate layer on the molding mold and embedding the connecting fastener into the cover plate layer during the laying process. The cover plate layer is cured in an autoclave.

[0016] Preferably, before placing the cover plate body in the preset position, the method further includes placing the cover plate body on the co-cured cap-shaped rib in the preset position.

[0017] The beneficial effects of this invention are: The process cover structure provided by this invention achieves a damage-free connection between the cover body and the connecting components by pre-embedding the connecting fasteners at both ends of the cover body. This avoids the damage to the structural integrity of the cover body caused by subsequent drilling or gluing operations in traditional connection methods. The connecting components adopt a split design, with the first and second connecting components respectively mating with the connecting fasteners at adjacent ends, and then the first and second connecting components are stably connected by locking components. This structure not only simplifies the installation process and improves on-site assembly efficiency, but also, because the connecting fasteners are pre-embedded during the forming of the cover body, their connection position accuracy is high and the stress is uniform, which is beneficial to improving the overall structure's load-bearing capacity and fatigue life. In addition, the design of the connecting fasteners protruding from the cover body provides a clear mating interface for the connecting components, facilitating quick positioning and fixing during installation, making the positioning and fit of the cover body simple and easy to place, especially suitable for large composite material co-cured wall panels.

[0018] The method for manufacturing a process cover plate structure provided by this invention first places the cover plate bodies in a preset position, ensuring the relative positional accuracy between each cover plate body. Then, the first and second connecting pieces are respectively connected to the connecting fasteners at both ends of the cover plate body. The connecting fasteners protruding from the cover plate body enable rapid mounting of the cover plate body to the connecting components. Finally, the first and second connecting pieces are connected and fixed using locking pieces, locking adjacent cover plate bodies together. The entire process is simple and convenient, and the connection between adjacent cover plate bodies is reliable and stable, which is beneficial for the subsequent shaping of parts. Furthermore, this method allows for segmented manufacturing and rapid assembly of the cover plate bodies, which is highly beneficial for the reliable connection of large-sized process cover plate structures.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0024] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0025] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0026] like Figures 1 to 5 As shown, this embodiment provides a process cover structure 200 for a co-cured body panel, including at least two cover bodies 1 and connecting components 2.

[0027] The cover plate body 1 includes connecting fasteners 11 embedded at both ends of the cover plate body 1, with the connecting fasteners 11 at least partially protruding from the cover plate body 1. The connecting assembly 2 includes a first connecting member 21, a second connecting member 22, and a locking member 23. The first connecting member 21 is connected to the connecting fastener 11 at one end of the cover plate body 1, the second connecting member 22 is connected to the connecting fastener 11 at the other end of the cover plate body 1, and the locking member 23 can connect and fix the first connecting member 21 and the second connecting member 22.

[0028] For example, such as Figure 1 and Figure 2 As shown, this embodiment includes three cover plate bodies 1, with two adjacent cover plate bodies 1 as an example. Each of the two cover plate bodies 1 has a connecting fastener 11 at the end where they are to be connected. The connecting assembly 2 can connect and fix the connecting fasteners 11 protruding from the two adjacent cover plate bodies 1 together. Specifically, the connecting fastener on the upper cover plate body 1 is connected to the first connecting fastener 21, and the fixing connecting fastener on the lower cover plate body 1 is connected to the second connecting fastener 22.

[0029] Understandably, the process cover structure 200 of this co-cured chassis panel achieves a damage-free connection between the cover body 1 and the connecting assembly 2 by pre-embedding the connecting fasteners 11 at both ends of the cover body 1. This avoids damage to the structural integrity of the cover body 1 caused by subsequent drilling or gluing operations in traditional connection methods. The connecting assembly 2 adopts a split design. After the first connecting piece 21 and the second connecting piece 22 are respectively connected to the connecting fasteners 11 at the adjacent ends, the first connecting piece 21 and the second connecting piece 22 are then stably connected by the locking piece 23. This structure not only simplifies the installation process and improves on-site assembly efficiency, but also ensures high connection accuracy and uniform stress distribution because the connecting fasteners 11 are pre-embedded during the molding of the cover body 1, which is beneficial to improving the overall structure's load-bearing capacity and fatigue life. In addition, the design of the connecting fasteners 11 protruding from the cover body 1 provides a clear docking interface for the connecting assembly 2, facilitating quick positioning and fixing during installation. This makes the positioning and fitting of the cover body 1 simple and easy, especially suitable for large composite material co-cured wall panels.

[0030] like Figure 4 and Figure 5 As shown, in some embodiments, both the first connector 21 and the second connector 22 include a connector 24 and an adapter. The connector 24 is used to connect with the corresponding connector 11. The connector 11 is provided with a locking block at one end away from the cover plate body 1. The connector 24 is provided with a slot that cooperates with the locking block. The adapter is used to connect with the locking member 23.

[0031] It is understandable that by setting a locking block at the end of the connecting fastener 11 and a matching slot on the connecting seat 24, a quick-release plug-in mating structure is formed between the connecting fastener 11 and the connecting seat 24. Initial positioning and pre-tightening can be completed without the need for special tools, significantly improving the convenience of on-site installation. The adapter provides a unified connection interface for the locking member 23, allowing both the first connecting member 21 and the second connecting member 22 to achieve axial alignment or eccentric adjustment via the locking member 23. This accommodates installation errors between different cover plate bodies 1, enhancing the structure's fault tolerance and adaptability. More specifically, the ends of the first connecting member 21 and the second connecting member 22 that are away from each other are connected to the connecting seat 24. The side of the connecting seat 24 with the slot is adapted to the surface of the cover plate body 1. When the locking block of the connecting fastener 11 protruding from the cover plate body 1 engages with the slot on the connecting seat 24, the connecting seat 24 on the first connecting member 21 and the second connecting member 22 can fit against the outer surface of the cover plate body 1.

[0032] In some embodiments, the transition portion of one of the first connector 21 and the second connector 22 is configured as a protrusion 25, and the transition portion of the other of the first connector 21 and the second connector 22 is configured as a groove 26 corresponding to the protrusion 25. The locking member 23 can pass through one side wall of the groove 26, the protrusion 25 and the other side wall of the groove 26 in sequence.

[0033] Specifically, such as Figure 4 and Figure 5 As shown, in this embodiment, the adapter portion of the first connector 21 is configured as a groove 26, and the adapter portion of the second connector 22 is configured as a protrusion 25.

[0034] Understandably, the engagement of the protrusion 25 and the groove 26 allows the first connector 21 and the second connector 22 to interlock during connection. After the protrusion 25 is inserted into the groove 26, the contact area between the first connector 21 and the second connector 22 increases significantly, enabling the transmission of larger tensile and compressive loads, as well as effective resistance to shear forces and bending moments, thereby significantly improving the overall stiffness and load-bearing capacity of the connecting assembly 2. The locking member 23 passes sequentially through one side wall of the groove 26, the protrusion 25, and the other side wall of the groove 26, connecting the protrusion 25 and the side wall of the groove 26 into a single unit. After the locking member 23 is locked, the protrusion 25 is firmly constrained within the groove 26, making relative movement almost impossible. This ensures that the connection between adjacent cover plate bodies 1 will not loosen due to external forces, guaranteeing the stability of the first connector 21 and the second connector 22 in complex environments.

[0035] More specifically, in this embodiment, the locking member 23 includes a bolt and a nut, the bolt being able to pass through the first connector 21 and the second connector 22 and be locked with the nut.

[0036] Understandably, both the first connector 21 and the second connector 22 have through holes matching the bolt diameter, and the groove 26 is also an open groove. Bolts and nuts are used as locking elements 23, so that before the bolts and nuts are tightened, the first connector 21 and the second connector 22 can adjust the angle between them under the action of the bolts and through holes, thereby satisfying the process cover structure 200 of co-cured body panels of different shapes. Moreover, when maintaining or replacing the cover body 1 in the future, the first connector 21 and the second connector 22 can be separated simply by loosening the nuts, which reduces maintenance costs.

[0037] In some embodiments, the connecting fastener 11 includes a pre-embedded part and a connecting part. The pre-embedded part is embedded inside the cover plate body 1, and the connecting part protrudes from the cover plate body 1. The connecting part is provided with a locking block for connecting with the first connecting member 21 or the second connecting member 22.

[0038] Specifically, in this embodiment, the connecting fastener 11 is a metal screw. The metal screw is pre-embedded within the cover plate body 1 during the molding process, with all its threaded portion embedded within the cover plate body 1. It can be understood that the connecting fastener 11 adopts an integrated structural design of the pre-embedded portion and the connecting portion, ensuring both the bonding strength with the cover plate body 1 and providing an exposed connection interface. The pre-embedded portion is completely embedded inside the cover plate body 1, forming a strong physical anchor or chemical bond with the base material during the molding process of the cover plate body 1. This effectively transfers external loads to the interior of the cover plate body 1, avoiding localized damage caused by stress concentration. The connecting portion protrudes from the end face of the cover plate body 1, providing independent space for the locking block, allowing the connecting fastener 11 to be independent of the thickness of the cover plate body 1, which is beneficial for the standardized design of the connecting assembly 2.

[0039] In order to improve the connection strength between the connecting fastener 11 and the cover plate body 1, in some embodiments, an anti-detachment structure is provided at the end of the pre-embedded part away from the connecting part.

[0040] It is understood that the anti-detachment structure includes, but is not limited to, bosses and / or barbs. The anti-detachment structure further enhances the anchoring performance of the connecting fastener 11 within the cover plate body 1. This avoids the risk of detachment or pull-out during long-term use, which could result from relying solely on interfacial adhesion between the embedded part and the cover plate body 1. The anti-detachment structure increases the contact area and mechanical interlocking force between the embedded part and the cover plate body 1, effectively preventing the connecting fastener 11 from being pulled out of the cover plate body 1 under tension, thus ensuring the safety of the connection structure during use.

[0041] In some embodiments, a plurality of connecting fasteners 11 are provided at the end of the cover plate body 1 along a first direction, and a plurality of connecting components 2 respectively connect and fix two corresponding connecting fasteners 11, the first direction being perpendicular to the connecting direction of the cover plate body 1.

[0042] Specifically, such as Figure 1 As shown in this embodiment, four fixing connectors are evenly spaced at the width direction of each end of the cover plate body 1. The four connectors on the upper cover plate body 1 are connected to four first connectors 21, and the four fixing connectors on the lower cover plate body 1 are connected to four second connectors 22.

[0043] Understandably, by arranging multiple connecting fasteners 11 along a first direction perpendicular to the connection direction at the end of the cover plate body 1, and using multiple connecting components 2 for corresponding connections, a multi-point distributed connection at the connection interface is achieved. This multi-point connection method can evenly distribute the force between the cover plate bodies 1 along the width direction, avoiding excessive concentrated loads on a single connection point, effectively reducing the peak stress in the connection area, and improving the fatigue strength and durability of the connection. For cover plate bodies 1 with a large width, multi-point connection can also effectively suppress warping or local deformation at the end of the cover plate under stress, ensuring the fit and sealing performance of the connection area.

[0044] This embodiment also provides a method for manufacturing a process cover structure 200 for a co-cured fuselage wall panel, applicable to the aforementioned process cover structure 200 for a co-cured fuselage wall panel, comprising: Place the cover plate body 1 in the preset position; Connect the first connector 21 and the second connector 22 to the connecting fastener 11 respectively; Locking member 23 connects the first connecting member 21 and the second connecting member 22 until the cover plate body 1 is connected end to end.

[0045] It is understandable that the manufacturing method of the process cover plate structure 200 for the co-cured fuselage wall panel provided in this embodiment first places the cover plate body 1 in a preset position, which can ensure the relative positional accuracy between each cover plate body 1. Then, the first connecting piece 21 and the second connecting piece 22 are respectively connected to the connecting fixing pieces 11 at both ends of the cover plate body 1. Through the connecting fixing pieces 11 protruding from the cover plate body 1, the connection between the cover plate body 1 and the connecting assembly 2 can be quickly installed. Finally, the first connecting piece 21 and the second connecting piece 22 are connected and fixed by the locking piece 23, so that the two adjacent cover plate bodies 1 are connected and locked together. The whole process is simple and convenient, and the connection between the two adjacent cover plate bodies 1 is firm and stable, which is beneficial to the subsequent shaping of the parts. Moreover, this method enables the cover plate body 1 to be manufactured in sections and quickly assembled, which is very beneficial for the reliable connection of the process cover plate structure 200 for large-sized co-cured fuselage wall panels.

[0046] More specifically, before placing the cover plate body 1 in the preset position, the process also includes laying the cover plate layer 12 on the molding mold 3, and embedding the connecting fastener 11 into the cover plate layer 12 during the laying process. The cover plate layer is cured in an autoclave.

[0047] In this embodiment, the molding mold 3 is selected according to the desired inner surface shape of the cover plate body 1. During the cover plate layup 12 process, after a certain number of layers are laid, the metal screw is placed on the layup of the cover plate body 1. After placement, the cover plate layup 12 continues to be laid until the desired cover plate body 1 is reached, and the subsequent cover plate layup 12 is hollowed out at the position corresponding to the metal screw.

[0048] Understandably, during the installation of the cover plate layup 12, the connecting fasteners 11 are pre-embedded simultaneously, allowing the connecting fasteners 11 to be co-cured with the cover plate body 1 substrate in one step during the autoclave curing stage. This creates a tight, interface-free bond between the two, eliminating gaps or adhesive layer defects that may exist with later-installed pre-embedded parts. Simultaneously, this ensures the continuity of the layup around the connecting fasteners 11, preventing damage to the cover plate body 1 caused by drilling or secondary bonding, and preserving the structural integrity of the cover plate body 1 to the greatest extent possible. Furthermore, autoclave curing significantly improves the peel resistance and long-term stability of the connection area between the connecting fasteners 11 and the cover plate layup 12.

[0049] In some embodiments, before placing the cover plate body 1 in a preset position, the method further includes placing the cover plate body 1 in a preset position on the co-cured cap-shaped rib 100.

[0050] In this embodiment, the process cover structure 200 of the co-cured fuselage panel is directly combined with the co-cured cap-shaped rib 100. It can be understood that the co-cured cap-shaped rib 100 is sleeve-shaped, and the process cover structure 200 of the co-cured fuselage panel is fitted onto the outside of the co-cured cap-shaped rib 100, thus forming a co-cured fuselage panel with strong integrity and high load-bearing efficiency, suitable for the efficient manufacturing of modern large aircraft fuselage sections.

[0051] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
