[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on December 22, 2023, with application number 202311785780.0 and invention name “Method for integrated laying and printing of composite material components”, the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the technical field of composite material manufacturing, and in particular to a method for integrated placement and printing of composite material components. Background Art

[0004] Layup technology uses prepreg tape as raw material, which is then softened and laid onto a mold or a previous prepreg tape using a roller, thereby forming the composite material. This technology features a high degree of automation and high production efficiency, and can be used to create products with different structures by designing the layup trajectory.

[0005] However, as composite materials become increasingly widely used, the structures of composite components are becoming increasingly diverse. Limited by the principles of layup forming technology, related layup forming technologies typically require the use of molds to provide support for composite components with complex structures. This involves laying composite materials on the mold to achieve the manufacture of composite components with diverse structures. Furthermore, due to the limitations of layup forming technology, the application scope of this technology is limited to the formation of composite components with small curvature and large surfaces. For composite components with locally complex structures, this technology is difficult to form individually in a single manufacturing process.

[0006] Therefore, in related technologies, before composite materials are laid and formed, it is usually necessary to design and manufacture a mold first. This is not only expensive, but also often has a long manufacturing cycle, which seriously restricts the forming efficiency and manufacturing cost of composite components.

[0007] Summary of the Invention

[0008] In view of this, the present application provides a method for integrated placement and printing of composite material components to solve the problems of high cost and low efficiency in the existing manufacturing of composite material components.

[0009] The present application provides a method for integrated placement and printing of composite material components, comprising: generating a support member within the first three-dimensional model based on a first three-dimensional model of the composite material component to obtain a second three-dimensional model of an intermediate component; 3D printing a portion corresponding to the support member based on the second three-dimensional model to obtain the support member; placing and forming a portion corresponding to the composite material component on the basis of the support member based on the second three-dimensional model to obtain an intermediate component; and peeling the support member off the intermediate component to obtain a composite material component.

[0010] Beneficial effects: It can be understood that the intermediate part includes a composite material component and a support member, and the support member is used to provide a forming surface for the composite material component. It should be noted that both layup forming and 3D printing forming are one of the forming methods of additive manufacturing. In this solution, by constructing a second three-dimensional model of the intermediate part, directly based on the second three-dimensional model, the part corresponding to the composite material component adopts a layup printing integrated forming process, and the part corresponding to the support member adopts a 3D printing forming process to obtain an intermediate part integrating the composite material component and the support member, and then the support member is peeled off to obtain the composite material component. In this way, during the layup printing integrated forming process, the support member can provide a forming surface for the composite material component, ensuring the reliability of the composite material component forming, which is conducive to the manufacture of composite material components with special shapes or complex structures. Therefore, the forming method of this solution realizes layup printing integrated forming, that is, the composite material component and the support member are formed into an intermediate part as a whole. With this arrangement, the composite material component does not need to be additively manufactured on the surface of the mold that has been additionally processed, saving the process of designing and manufacturing the mold, reducing the manufacturing cost of the composite material component, and improving production efficiency.

[0011] In an optional embodiment, based on the second three-dimensional model, on the basis of the support member, the portion corresponding to the composite material component is integrally formed by layup printing. In the step of obtaining the intermediate part, the main portion of the composite material component is obtained by layup printing, and the local structure of the composite material component is obtained by 3D printing. Specifically, the process includes the steps of: layup printing the main portion first, then 3D printing the local structure; or 3D printing the local structure first, then layup printing the main portion; or, simultaneously layup printing the main portion and 3D printing the local structure.

[0012] Advantageous Effects: The invention facilitates the manufacture of special-shaped composite components, providing a high degree of freedom in forming. The local structure of the composite component refers to holes or reinforcing ribs, etc. Specifically, the composite materials used in the main portion and the local structure of the composite component can be the same or different, that is, the reinforcing fibers and resin matrix used in the main portion and the local structure can be different.

[0013] In an optional embodiment, the step of obtaining a second three-dimensional model of the intermediate part based on the first three-dimensional model of the composite material component includes: constructing the first three-dimensional model through three-dimensional software; based on the first three-dimensional model, the three-dimensional software generates a third three-dimensional model of the support part; based on the first three-dimensional model and the third three-dimensional model, the three-dimensional software generates a second three-dimensional model.

[0015] In an optional embodiment, the composite material component is made of fiber-reinforced thermoplastic composite material, and the support member is made of soluble resin.

[0016] Beneficial effects: Fiber-reinforced thermoplastic composite materials facilitate the production of high-quality composite components through integrated placement and printing, while the support member adopts a soluble resin, which facilitates the peeling of the support member from the intermediate member after the intermediate member is obtained.

[0017] In an optional embodiment, the fiber-reinforced thermoplastic composite material includes a resin matrix and reinforcing fibers, and the reinforcing fibers are at least one of carbon fibers, glass fibers, and aramid fibers; optionally, in the fiber-reinforced thermoplastic composite material, the reinforcing fibers are made of at least one of carbon fiber-reinforced polyphenylene sulfide, carbon fiber-reinforced polyetheretherketone, carbon fiber-reinforced polyaryletherketone, carbon fiber-reinforced nylon, carbon fiber-reinforced polyetherimide, aramid fiber-reinforced polylactic acid, aramid fiber-reinforced nylon, and glass fiber-reinforced polyetheretherketone; and the resin matrix is ​​of the same material.

[0018] Beneficial effect: It is easy to obtain composite components with higher performance and quality.

[0019] In an optional embodiment, the step of peeling the support member off the intermediate member to obtain the composite material component includes the step of: performing a bath treatment on the intermediate member.

[0020] Beneficial effects: Since the material of the support is soluble resin, after the intermediate workpiece is bath-treated, the support can be automatically separated from the composite material component, which is easy to operate and highly efficient, thereby further improving the production efficiency of the composite material component and reducing production costs.

[0021] In an optional embodiment, before the step of 3D printing the portion corresponding to the support member according to the second three-dimensional model to obtain the support member, the step further includes: layering the second three-dimensional model to obtain cross-sectional profile information of each layer. Specifically, in the step of 3D printing the portion corresponding to the support member according to the second three-dimensional model to obtain the support member, 3D printing is performed layer by layer according to the cross-sectional profile information of each layer. In the step of laying and printing the portion corresponding to the composite material component on the basis of the support member according to the second three-dimensional model to obtain the intermediate part, laying and printing the portion corresponding to the composite material component is performed layer by layer according to the cross-sectional profile information of each layer.

[0022] Beneficial effects: manufacturing is performed layer by layer according to the cross-sectional profile information of each layer of the second three-dimensional model, with high manufacturing accuracy and reliability, and composite material components with complex structures can be manufactured with strong versatility.

[0023] In an optional embodiment, during the step of 3D printing each layer according to the cross-sectional profile information of each layer, a resin printing mechanism is used to extrude a soluble resin and solidify it.

[0035] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0036] Composite materials, due to their low specific gravity, high specific strength and modulus, high temperature resistance, and strong designability, have been increasingly widely used in aerospace, military, infrastructure, transportation, wind power, and other fields in recent years. This has led to higher demands on composite forming technologies. Among them, layup forming technology, a more advanced composite forming technology, uses prepreg tape as the raw material. After heating and softening, it is laid onto a mold or the previous prepreg tape using a roller, thereby achieving the layup formation of the composite material. This technology features a high degree of automation and high production efficiency, and can be used to design the layup trajectory to produce products with different structures.

[0037] However, traditional composite material placement molding technology has obvious disadvantages such as high energy consumption, long production cycle, and greater environmental pollution. At the same time, the principle of placement molding technology determines that the first layer of composite material needs to be laid on the mold during its process. Existing placement molding technology usually requires expensive and time-consuming mold casting or processing operations before the actual composite material manufacturing begins, which restricts the molding efficiency and manufacturing cost of composite material components, especially in rapid and one-time prototyping. This restriction is particularly obvious. To solve this problem, the present application proposes a placement and printing integrated molding method and operating machinery for composite material components.

[0038] [Corrected 10.01.2024 according to Rule 91] The following describes an embodiment of the present application in conjunction with Figures 1 to 3.

[0039] According to an embodiment of the present application, on the one hand, a method for integrated placement and printing of a composite material component is provided. Referring to FIG. 1 to FIG. 3 , the method for integrated placement and printing of a composite material component comprises the following steps:

[0040] S10: Based on the first three-dimensional model 11a of the composite component 11, a support member 12 is generated within the first three-dimensional model 11a to obtain a second three-dimensional model 10a of the intermediate component 10;

[0041] S20: Based on the second three-dimensional model 10a, the portion corresponding to the support member 12 is 3D printed to obtain the support member 12;

[0042] S30: Based on the second three-dimensional model 10a, on the basis of the support member 12, the portion corresponding to the composite material component 11 is laid out and printed for integrated formation to obtain the intermediate component 10;

[0043] S40: Peeling the support member 12 off the intermediate member 10 to obtain the composite material component 11.

[0044] Specifically, in step S10 , the intermediate component 10 includes a composite material component 11 and a support component 12 , and the support component 12 is used to provide a forming surface for the composite material component 11 .

[0045] It should be noted that both lay-up forming and 3D printing forming are one of the forming methods of additive manufacturing. In this embodiment, by constructing a second three-dimensional model 10a of the intermediate part 10, additive manufacturing is performed directly on the basis of the second three-dimensional model 10a, the part corresponding to the composite material component 11 adopts the lay-up forming process, and the part corresponding to the support member 12 adopts the 3D printing forming process, thereby obtaining the intermediate part 10 integrating the composite material component 11 and the support member 12, and then the support member 12 is peeled off to obtain the composite material component 11. In this way, in the process of lay-up printing integrated forming, the support member 12 can provide a forming surface for the composite material component 11, ensure the reliability of the forming of the composite material component 11, and facilitate the manufacture of composite material components 11 with special shapes or complex structures.

[0046] Therefore, the forming method of this embodiment is adopted to realize the integrated forming of laying and printing, that is, 3D printing forming of the support part. On the basis of the support part, the composite material component 11 is formed by laying and printing integration, and the composite material component 11 and the support part 12 are integrally formed into an intermediate part 10. With this arrangement, the composite material component 11 does not need to be additively manufactured on the surface of the mold that has been additionally processed, which saves the process of designing and manufacturing the mold, reduces the manufacturing cost of the composite material component 11, and improves production efficiency.

[0047] In some embodiments, in step S30, the main body of the composite material component is obtained by layup forming, and the local structure of the composite material component is obtained by 3D printing forming.

[0048] Specifically, the process includes the following steps:

[0049] After laying out the main body, 3D print the local structure.

[0050] Or after 3D printing the local structure, lay out the main part;

[0051] Alternatively, the main body of the part can be printed and the local structure can be 3D printed at the same time.

[0052] The method of this embodiment facilitates the manufacture of special-shaped composite components, providing a high degree of freedom in forming. The local structures of the composite component refer to holes or reinforcing ribs, for example. Specifically, the composite materials used in the main portion and the local structures of the composite component can be the same or different, meaning that the reinforcing fibers and resin matrix used in the main portion and the local structures can be different.

[0053] For example, the first three-dimensional model 11a can be constructed in three-dimensional software, and according to the specific shape of the first three-dimensional model 11a, the shape of the support member 12 can be directly generated by the three-dimensional software to obtain the second three-dimensional model 10a.

[0054] Specifically, step S10 includes:

[0055] S11: constructing a first three-dimensional model 11a using three-dimensional software;

[0056] S12: Based on the first three-dimensional model 11a, the three-dimensional software generates a third three-dimensional model of the support member 12;

[0057] S13: Based on the first three-dimensional model 11a and the third three-dimensional model, the three-dimensional software generates a second three-dimensional model 10a.

[0058] In this embodiment, three-dimensional software is used for drawing, which saves manpower, has high accuracy and reliability, and facilitates automatic control.

[0059] Generally, the first three-dimensional model 11 a requires the support member 12 to provide a shaping surface at a portion having a curved surface structure or a portion adjacent to a hollow structure.

[0060] The present application does not impose any specific limitation on the shape of the support member 12 , as long as it can achieve the function of supporting the composite material component 11 .

[0061] It can be understood that the composite material component provided by the present application is not limited to the structure shown in Figure 2. The composite material component can be constructed into any special-shaped structure or a structure with a regular shape, as long as it can be obtained through the placement and printing integrated forming method of the present application.

[0062] In some embodiments, the composite component 11 is made of a fiber-reinforced thermoplastic composite material, and the support member 12 is made of a soluble resin. The fiber-reinforced thermoplastic composite material facilitates the production of high-quality composite component 11 through integrated placement and printing, while the support member 12 is made of a soluble resin, which facilitates the removal of the support member 12 from the intermediate component 10 after the intermediate component 10 is obtained.

[0063] Exemplarily, the fiber-reinforced thermoplastic composite material includes a resin matrix and reinforcing fibers, wherein the reinforcing fibers may include at least one of carbon fibers, glass fibers, and aramid fibers. Optionally, in the fiber-reinforced thermoplastic composite material, the reinforcing fibers may be made of at least one of carbon fiber-reinforced polyphenylene sulfide, carbon fiber-reinforced polyetheretherketone, carbon fiber-reinforced polyaryletherketone, carbon fiber-reinforced nylon, carbon fiber-reinforced polyetherimide, aramid fiber-reinforced polylactic acid, aramid fiber-reinforced nylon, and glass fiber-reinforced polyetheretherketone; and the resin matrix may be made of the same material. Of course, the resin matrix may also be made of different materials.

[0064] Illustratively, the soluble resin includes at least one of polyvinyl alcohol resin and acrylic copolymer, both of which are water-soluble, making it easier to peel off the support member 12 .

[0065] Furthermore, in step S30, the following steps are included:

[0066] S31: The intermediate product 10 is subjected to a bath treatment.

[0067] In this embodiment, since the material of the support member 12 is soluble resin, after the intermediate workpiece 10 is bath-treated, the support member 12 can be automatically separated from the composite material component 11, which is easy to operate and highly efficient, thereby further improving the production efficiency of the composite material component 11 and reducing production costs.

[0068] For example, the support member 12 is made of a water-soluble resin, and the bath treatment can be a water bath. In this case, the specific implementation method of step S31 is: immerse the intermediate workpiece 10 in a larger container filled with water, then place the larger container on a heat source to heat it, stop heating when it reaches an appropriate temperature, and remove it after cooling.

[0069] In some embodiments, before step S20, the following steps are included:

[0070] S21: Layer the second three-dimensional model 10a to obtain cross-sectional profile information of each layer.

[0071] Specifically, in step S20: 3D printing is performed layer by layer according to the cross-sectional profile information of each layer.

[0072] In step S30: laying and integrated forming are performed layer by layer according to the cross-sectional profile information of each layer.

[0073] In this embodiment, the second three-dimensional model 10a is manufactured layer by layer according to the cross-sectional profile information of each layer. The manufacturing accuracy and reliability are high, and a composite material component 11 with complex structure can be manufactured with strong versatility.

[0074] For example, slicing software may be used to slice the second three-dimensional model 10a and obtain cross-sectional profile information of each layer, with a high degree of automation.

[0075] In some embodiments, in the step of performing 3D printing layer by layer according to the cross-sectional profile information of each layer, when printing each layer, a resin printing mechanism is used to extrude a soluble resin and solidify it into shape.

[0076] In the step of laying out the integrated formation layer by layer according to the cross-sectional profile information of each layer: the main part of the composite material component 11 is formed by laying the composite material by a laying mechanism and solidifying it; the local structure of the composite material component 11 is formed by extruding the composite material by a composite material printing mechanism and solidifying it.

[0077] The portion corresponding to the composite material component 11 is formed by laying the composite material using a laying mechanism and solidifying it; the portion corresponding to the support member 12 is formed by extruding the soluble resin using a resin printing mechanism and solidifying it.

[0078] In this embodiment, the corresponding parts of the composite material component 11 and the corresponding parts of the support member 12 are manufactured respectively by the laying mechanism, the composite material printing mechanism and the resin printing mechanism, which facilitates the integrated laying and printing forming, shortens the manufacturing cycle and improves production efficiency.

[0079] Exemplarily, the execution unit includes a laying mechanism, a resin printing mechanism, and a composite material printing mechanism.

[0080] During application, the execution unit moves to the area where the support member 12 is located, and the resin printing mechanism in the execution unit prints the support member 12 .

[0081] Then, the composite material mechanism 11 is laid, printed and integrated into a formation. Specifically, when the execution unit runs to the area where the main part of the composite material component 11 is located, the laying mechanism lays the composite material; when it runs to the area where the local structure of the composite material component 11 is located, the composite material printing mechanism performs 3D printing of the composite material.

[0082] In some embodiments, step S includes the steps of:

[0083] S211: generating a forming path for each layer according to the cross-sectional profile information of each layer;

[0084] S212: The control unit generates a control program according to the forming path of each layer;

[0085] S213: The execution unit performs the manufacturing and forming of each layer according to the control program.

[0086] In this embodiment, the control program controls the execution unit to manufacture and form the intermediate component 10, which has a high degree of automation and high execution accuracy, and is conducive to obtaining a high-quality and complex structure composite material component 11.

[0087] In some embodiments, after step S40, the method further includes the following steps:

[0088] S50: Post-processing the composite material component 11.

[0089] Specifically, the above post-processing includes one or more of the following steps:

[0090] S51: Grinding the surface and edge of the composite material component 11;

[0091] S52: Finishing the composite material component 11.

[0092] This embodiment is conducive to obtaining a high-precision, high-quality composite material component 11, thereby improving customer satisfaction.

[0093] The finishing in step S42 may include further finishing the size or shape of the composite material component 11 .

[0094] The following is an example to illustrate the method, wherein the material of the composite material component 11 is selected from carbon fiber reinforced polyetheretherketone resin; the resin is selected from polyvinyl alcohol resin. Specifically, the forming method of the composite material component 11 includes the following steps:

[0095] The shape of the target composite material component 11 is drawn in a 3D software to obtain a first 3D model 11a; and the 3D software automatically generates a 3D model of the support member 12 required for the composite material component 11, thereby obtaining a second 3D model 10a;

[0096] Utilizing slicing software and numerical control programming software for additive manufacturing processes to perform path planning on the intermediate component 10 composed of the composite component 11 and the support member 12 and generate processing code;

[0097] In the laying mechanism, the composite material roll is carbon fiber reinforced polyetheretherketone resin; in the resin printing mechanism, the resin roll is polyvinyl alcohol resin. The execution unit lays and prints on the processing platform, and the laying angle of the laying mechanism is 0°. The laying mechanism, resin printing mechanism, and composite material printing mechanism in the execution unit are used to lay or print layer by layer to obtain the intermediate product 10. During the processing, when the execution unit runs to the area where the support member 12 is located, the resin printing mechanism extrude molten polyvinyl alcohol resin and completes the solidification to form the support member 12; when the execution unit runs to the area where the composite material component 11 is located, the laying mechanism lays strip carbon fiber reinforced polyetheretherketone resin on the processing platform, and solidifies it to form the main part of the composite material component 11; the composite material printing mechanism extrude molten carbon fiber reinforced polyetheretherketone resin and solidifies it to finally obtain the completed intermediate product 10;

[0098] The intermediate product 10 is subjected to a water bath treatment to separate the support member 12 from the composite material component 11;

[0099] The composite material component 11 obtained after separation is post-processed to obtain a finished composite material component 11 .

[0100] The integrated composite material component placement and printing method provided herein combines the composite material placement process with the placement mold manufacturing process, eliminating the expensive and time-consuming mold casting or processing operations before composite material placement. This reduces the overall composite material placement process time, improving production efficiency and reducing costs compared to traditional composite material placement technologies. Furthermore, composite material placement no longer relies on existing molds, allowing the production of complex-shaped composite material components 11 on a flat substrate, increasing production flexibility.

[0101] Furthermore, the present invention utilizes a water-soluble resin to print and manufacture the support member 12, which is easily removable after forming, facilitating industrial applications. Furthermore, the present invention reduces the impact of mold precision on the precision of the target component. The target component is free from the constraints of existing molds and can have free-form edges, patches, or cutouts, allowing for optimal performance.

[0102] Although the embodiments of the present application have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations shall fall within the scope defined by the appended claims.
