[0024] Composite material layups are made by layering fiber cloth, resulting in superior performance and applications across numerous fields, particularly in aerospace. In the manufacturing of composite products (such as skins), manual layup is a widely used method. Specifically, pre-cut composite prepregs are laid sequentially onto molding fixtures using a template for positioning, following the layup order.

[0025] With technological advancements, the above methods, due to their low positioning accuracy, low cutting efficiency, and poor process operability, have been gradually replaced by fully automated methods. Currently, the main steps of the fully automated method are: first, according to the layup sequence of the composite material product, to create a layup model of the product using layup modeling software such as FiberSIM (commonly known as FiberSIM composite material design software) or the CPD (CompositeDesign) module in CATIA; then, using the aforementioned software, to convert and output manufacturing data such as the required prepreg sheet data and the contour data of each layup into a dedicated program, which performs CNC cutting and laser projection positioning, thereby improving the efficiency and accuracy of the composite material product manufacturing process.

[0026] Traditional tiling methods often employ single-layer or multi-layer tiling with aligned seams, which can easily lead to stress concentration and insufficient interlayer strength. This is especially true for closed, ring-shaped components, where traditional tiling methods struggle to guarantee both quality and efficiency due to their unique shape.

[0027] In view of this, embodiments of this application provide a laying method that improves the laying quality and strength of composite material components by forming at least two layups and staggering the seams of adjacent layups. A detailed description follows.

[0028] This application provides a method for laying components, including the following: At least two plies are formed, each ply having multiple paving areas, with a seam between each pair of adjacent paving areas, and the seams of adjacent plies are staggered.

[0029] In some embodiments, the paving surface of the component is a non-closed boundary profile. The component has multiple plies, each ply having multiple paving areas. A seam is provided between every two adjacent paving areas, and the seams of adjacent plies are staggered to improve the paving quality and strength of the component.

[0030] Please see Figure 1 and Figure 2 , Figure 1 This is a structural diagram of the first ply of the component. Figure 2 This is a structural diagram of the second ply of the component, wherein the second ply 20 has the same shape and size as the first ply 10. Figure 2 In the first layer 10, there are multiple first laying areas 11, and a first seam 12 is provided between each two adjacent first laying areas 11. Figure 2 In the second layup 20, there are multiple second laying areas 21, and a second joint 22 is provided between each pair of adjacent second laying areas 21. The first joint 12 and the second joint 22 are staggered on the same plane of the component 100.

[0031] In one example, the seams of each ply do not overlap in the orthographic projection onto the same plane of component 100. This ensures that the seams of each ply are covered by the intact prepreg of adjacent plies, allowing external forces to be distributed and transferred through multiple layers of fibers. This prevents stress concentration in a single location, significantly improving the tensile, flexural, and fatigue strength of component 100. In other words, overlapping orthographic projections of the seams of multiple plies, meaning the seams are aligned along the thickness direction of component 100, create a weak line running through the plies. When component 100 is subjected to external forces, such as aerodynamic loads or vibration loads in the aerospace field, stress will preferentially accumulate along this weak line, leading to uneven stress on local fibers, resin cracking, and even the risk of delamination and breakage of component 100.

[0032] In this embodiment, component 100 is a composite material component, and the material of the layup is a prepreg, which is a fiber material impregnated with a resin matrix.

[0033] Layup modeling software, such as FiberSIM or the CPD (Composite Design) module in CATIA, requires, based on geometric principles, that the boundaries of the layup profile during the layup modeling process must be closed contours. During the layup of composite components, the layup profile of the component must be completely covered by prepreg. Since the width of prepreg is limited, when the layup profile is larger than the width of the prepreg, multiple pieces of prepreg need to be spliced ​​on the layup profile to ensure complete prepreg coverage. Simultaneously, to ensure product quality, the splices of layups with the same angle cannot be in the same location. These requirements are easily met when the layup profile is not closed. Figure 3 and Figure 4 The diagram shows the boundary profile forms of different types of non-closed surfaces. Figure 1 and Figure 2 The diagram shows the staggered joints of ply layers with the same angle when the area of ​​the paving profile is larger than the width of the prepreg. However, when the paving profile of component 100 is a closed contour, the boundary contour needs to be changed to a closed contour to meet the software's ply modeling requirements, such as... Figure 5 As shown, this will result in a non-closed area 101 always existing on component 100 during the subsequent layer modeling process. This directly leads to the fact that even if the non-closed area 101 (hereinafter referred to as the gap area) is filled with prepreg during the subsequent laying process, the filling position of all layers is exactly the same, resulting in a decrease in the internal quality of the product.

[0034] Figure 6 This is a schematic diagram of the first layer structure with a closed profile. Figure 7 This is a schematic diagram of the second ply structure with a closed profile.

[0035] Specifically, please refer to Figure 6 and Figure 7The notch areas of the first ply 10' and the second ply 20' project onto the component, meaning the notch areas of each ply are aligned in the thickness direction of the component 100', thus forming a weak area that runs through multiple layers. Figure 5 The structure. When component 100' is subjected to external forces, such as aerodynamic loads or vibration loads in the aerospace field, stress will preferentially accumulate in this weak area, leading to uneven stress on local fibers, resin cracking, and even the risk of delamination and breakage of component 100'.

[0036] Please see Figures 8 to 11 This application also provides a method for laying the substrate, including the following steps: S11. At least two closed profiles are formed on the closed structural surface, and the overlapping area of ​​the at least two closed profiles completely covers the area of ​​the component.

[0037] A closed structural surface refers to the physical base surface of the component 100 to be manufactured, which is the carrier for prepreg laying.

[0038] The closed profile is a closed profile designed on a closed structural surface with at least two closed region boundaries to adapt to the hard rules of closed boundary in software such as FiberSIM and CATIA CPD, which require ply modeling based on closed boundaries. It serves as a digital benchmark for ply modeling.

[0039] Component 100 is a closed annular component, which includes at least one of a circular annular component, an elliptical annular component, a square annular component, a rectangular annular component, or an irregularly shaped annular component. The closed annular component has a flanged structure.

[0040] S12. Use one of at least two closed contours as the first reference contour.

[0041] S13. Based on the first reference profile, a first ply 10 with multiple first paving areas 11 is formed, and a first seam 12 is provided between each two adjacent first paving areas 11.

[0042] Based on the first reference profile, a complete digital model of the first ply 10 can be generated in the software, clarifying the core parameters such as the profile range and fiber angle of the first ply 10.

[0043] Please see Figure 12 Step S13 includes: S131. The first layup 10 is cut to make the first layup 10 have multiple first laying areas 11.

[0044] Based on the dimensions of the first reference profile, the first layup 10 is divided into multiple small first laying areas 11 according to the width of the prepreg, with each area corresponding to a sheet of prepreg. The multiple first laying areas 11 are spliced ​​together to cover the surface area of ​​the entire first reference profile, which not only solves the problem of insufficient prepreg width, but also leaves room for adjustment of the misalignment of the seams of the subsequent second layup 20.

[0045] The cutting process of the first layup 10 and the division of the first laying area 11 are based on the digital model of the first layup 10, providing data support for fully automated manufacturing processes such as CNC cutting of prepreg and laser projection positioning laying, and solving the problems of low positioning accuracy and poor efficiency of traditional manual laying.

[0046] S132. Identify the first ply 10 that does not overlap with the surface of the component 100 as the first gap region 13.

[0047] When modeling the first ply 10, the surface area of ​​the first reference profile can be compared with the actual effective surface area of ​​the component 100 through software, thereby quickly locating the deviation area between the two, namely the first gap area 13.

[0048] S133, Remove the first paving area 11 on both sides of the gap area to form the filling area 14.

[0049] By removing the first laying area 11 on both sides of the gap area, a filling area 14 is formed, which is a new cutting area reserved for filling the subsequent second layup 20, thus avoiding the problem of all layups being filled in the same position in the traditional process.

[0050] Therefore, after modeling and identifying the first reference contour, the area 14 can be accurately located and filled in, and complementary coverage can be achieved by dividing the second contour to improve the quality of component 100.

[0051] S14. Use another closed contour from at least two closed contours as the second reference contour.

[0052] S15. According to the second reference profile, a second ply 20 having a plurality of second paving areas 21 is formed on the first ply 10. A second joint 22 is provided between each two adjacent second paving areas 21. The second joint 22 and the first joint 12 are offset from each other in the orthographic projection on the same plane of the component 100.

[0053] Based on the second reference profile, a complete digital model of the second ply 20 can be generated in the software, clarifying the core parameters such as the profile range and fiber angle of the second ply 20.

[0054] Since the first seam 12 exists only at a specific location in the first ply 10, the second seam 22 is designed to be distributed on the first paving area 11 of the two adjacent first seams 12. That is, the orthographic projection of the second seam 22 on the first ply 10 lies between the two adjacent first seams 12, thus ensuring that the first seams 12 and the second seam 22 do not overlap on the plane of the component 100. It can be understood that all the first seams 12 of the first ply 10 are completely covered by the prepreg of the second ply 20, and all the second seams 22 of the second ply 20 are completely covered by the prepreg of the first ply 10. With this arrangement, when external forces act on the component 100, the stress will not concentrate at a single location on the component 100, but will be dispersed and transmitted through multiple layers of continuous fibers, significantly reducing local stress peaks and fundamentally avoiding the risk of structural failure due to overlapping seams.

[0055] In one example, the second ply 20 is cut based on the edge line of the fill area 14, so that the second ply 20 has multiple second ply areas 21, wherein the first second ply area 21 covers the fill area 14.

[0056] Using the edge line of the filling area 14 as a reference, the second layup 20 is cut, ensuring that the outline of the first second layup area 21 perfectly matches the edge of the filling area 14. This avoids gaps due to insufficient filling caused by cutting the layup too small, and also prevents prepreg redundancy due to excessive size, which could cover unnecessary areas of the component 100 and increase subsequent trimming costs. This design solves the problems of incorrect size estimation, missed layup, or high redundancy in traditional manual filling, ensuring that the surface of the component 100 is 100% free of gaps, thereby meeting the strength and quality requirements of the component 100. In this embodiment, the first notch area 13 is the deviation area between the surface corresponding to the first reference profile and the surface of the component 100. This deviation area needs to be covered by the second laying area 21 to achieve complete laying of the surface of the component 100. If it is not covered by the second laying area 21, the deviation area will become a blank area without prepreg coverage.

[0057] In one example, closed-loop components 100, such as aviation pipe joints and engine casings, have extremely high requirements for full-surface prepreg coverage. Blank areas can directly lead to localized fiber loss and insufficient resin support, making them highly susceptible to cracking and deformation under external forces. By covering and precisely filling these gaps with the second prepreg area 21, it is ensured that every effective surface of component 100 is covered with prepreg, thereby further enhancing the structural strength of component 100.

[0058] The joints of each ply do not overlap in the orthographic projection on the same plane of the component 100. In this way, the joints of each ply are covered by the complete prepreg of the adjacent ply. External forces can be dispersed and transmitted through multiple layers of fibers, avoiding stress concentration in a single location, thereby significantly improving the tensile, bending and fatigue strength of the component 100.

[0059] It should be noted that since component 100 is composed of multiple layers, during the installation process, the target layer is used as the initial layer of the previous layer. This provides an immediate and precise physical base for the target layer. For example, the second layer 20 uses the structure of the first layer 10 as a reference, ensuring that after the second layer 20 is formed, it can cover the filling area 14. Furthermore, the second joint 22 of the second layer 20 is offset from the first joint 12 of the first layer 10, ensuring that the surface of component 100 is 100% free of gaps and ensuring fiber continuity and uniform resin distribution, without localized strength or stiffness deviations.

[0060] Please see Figures 13 to 18 This application also provides a method for laying the substrate, including the following steps: S21. At least two closed profiles are formed on the closed structural surface, and the overlapping area of ​​the at least two closed profiles completely covers the area of ​​the member 100.

[0061] A closed structural surface refers to the physical base surface of the component 100 to be manufactured, which is the carrier for prepreg laying.

[0062] The closed profile is a closed profile designed on a closed structural surface with at least two closed region boundaries to adapt to the hard rules of closed boundary in software such as FiberSIM and CATIA CPD, which require ply modeling based on closed boundaries. It serves as a digital benchmark for ply modeling.

[0063] Component 100 is a closed annular component, which includes at least one of a circular annular component, an elliptical annular component, a square annular component, a rectangular annular component, or an irregularly shaped annular component. The closed annular component has a flanged structure.

[0064] S22. Use one of at least two closed contours as the first reference contour.

[0065] S23. Based on the first reference profile, a first ply 10 with multiple first paving areas 11 is formed, and a first seam 12 is provided between each two adjacent first paving areas 11.

[0066] Based on the first reference profile, a complete digital model of the first ply 10 can be generated in the software, clarifying the core parameters such as the profile range and fiber angle of the first ply 10.

[0067] S231. The first layup 10 is cut to make the first layup 10 have multiple first paving areas 11.

[0068] Based on the dimensions of the first reference profile, the first layup 10 is divided into multiple small first laying areas 11 according to the width of the prepreg, with each area corresponding to a sheet of prepreg. The multiple first laying areas 11 are spliced ​​together to cover the surface area of ​​the entire first reference profile, which not only solves the problem of insufficient prepreg width, but also leaves room for adjustment of the misalignment of the seams of the subsequent second layup 20.

[0069] The cutting process of the first layup 10 and the division of the first laying area 11 are based on the digital model of the first layup 10, providing data support for fully automated manufacturing processes such as CNC cutting of prepreg and laser projection positioning laying, and solving the problems of low positioning accuracy and poor efficiency of traditional manual laying.

[0070] S232. Identify the first ply 10 that does not overlap with the surface of the component 100 as the first gap region 13.

[0071] When modeling the first ply 10, the surface area of ​​the first reference profile can be compared with the actual effective surface area of ​​the component 100 through software, thereby quickly locating the deviation area between the two, namely the first gap area 13.

[0072] S24. Use another closed profile from at least two closed profiles as the second reference profile.

[0073] S25. According to the second reference profile, a second ply 20 having a plurality of second paving areas 21 is formed on the first ply 10. A second joint 22 is provided between each two adjacent second paving areas 21. The second joint 22 and the first joint 12 are offset from each other in the orthographic projection on the same plane of the component 100.

[0074] Based on the second reference profile, a complete digital model of the second ply 20 can be generated in the software, clarifying the core parameters such as the profile range and fiber angle of the second ply 20.

[0075] S251. The second layup 20 is cut to make the second layup 20 have multiple second laying areas 21.

[0076] Based on the dimensions of the second reference profile, the second layup 20 is divided into multiple small-sized second laying areas 21 according to the width of the prepreg, with each area corresponding to two pieces of prepreg. The multiple second laying areas 21 are spliced ​​together to cover the surface area of ​​the entire second reference profile, which not only solves the problem of insufficient prepreg width, but also reserves adjustment space for the misalignment of subsequent layups (such as the third layup).

[0077] The cutting process of the second layup 20 and the division of the second laying area 21 are based on the digital model of the second layup 20, which provides data support for fully automated manufacturing processes such as CNC cutting of prepreg and laser projection positioning laying, and solves the problems of low positioning accuracy and poor efficiency of traditional manual laying.

[0078] S252. Identify the second ply 20 that does not overlap with the surface of the component 100 as the second gap region 23, wherein the second gap region 23 and the first gap region 13 are offset on the same plane of the component 100.

[0079] When modeling the second ply 20, the surface area of ​​the second reference profile can be compared with the actual effective surface area of ​​the component 100 through software, thereby quickly locating the deviation area between the two, namely the second gap area 23.

[0080] The second notch region 23 and the first notch region 13 are offset on the same plane of the component 100. This allows the prepreg of the second layup 20 to cover the first notch region 13 of the first layup 10, and the prepreg of the first layup 10 to cover the second notch region 23 of the second layup 20, ensuring that the surface of the component 100 is 100% free of voids, thereby meeting the strength and quality requirements of the component 100. The orthographic projections of the seams of each ply on the same plane of component 100 are all non-overlapping, and the orthographic projections of the gap areas of each ply on the same plane of component 100 are all non-overlapping. In this way, the seams of each ply are covered by the complete prepreg of the adjacent ply, and external forces can be dispersed and transmitted through multiple layers of fibers, avoiding stress concentration in a single location, thereby significantly improving the tensile, bending and fatigue strength of component 100.
