When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0032] The first aspect of the present application provides a method for forming a composite layer structure. Figure 1 1 is a schematic diagram of a process flow of an embodiment of a method for forming a composite layer structure provided by the present application. Figure 1 , the method comprises the following steps:

[0033] S101: prefabricate a base layer and a laminating layer, and laminate an adhesive layer and an inorganic fiber layer between the base layer and the laminating layer.

[0034] Among them, the base layer can be a structural layer made of heterogeneous materials. Heterogeneous materials are materials with new structures and properties prepared by two or more different materials through specific methods. The bonding layer can be a structural layer made of composite materials. Composite materials are a multiphase solid material composed of two or more substances with different physical and chemical properties. Since electrical corrosion can occur when heterogeneous materials are in direct contact with composite materials, electrical corrosion can occur when the base layer is in direct contact with the bonding layer.

[0035] In some specific application scenarios, the base layer can be a metal layer, in which case the base layer can be made of a metal heterogeneous material, and at least part of the various materials in the metal heterogeneous material are metal materials. The bonding layer can be a carbon fiber layer, in which case the carbon fiber layer can be made of a carbon fiber composite material, and at least part of the various materials in the carbon fiber composite material are carbon fiber materials. In the process of prefabricating the bonding layer, a composite material layer can be made of carbon fiber raw materials and epoxy resin to serve as the bonding layer.

[0036] When the adhesive layer and the inorganic fiber layer are stacked between the base layer and the laminating layer, the order of arranging the adhesive layer and the inorganic fiber layer is not specifically limited in this embodiment. After the adhesive layer and the inorganic fiber layer are stacked between the base layer and the laminating layer, the four structural layers are initially laminated together to form a whole.

[0037] Figure 2 It is a structural diagram of a configuration of a base layer, a laminating layer, an adhesive layer and an inorganic fiber layer. Figure 3 It is a structural schematic diagram of another arrangement of the base layer, the laminating layer, the adhesive layer and the inorganic fiber layer.

[0038] like Figure 2 As shown, in one arrangement, the adhesive layer can be arranged close to the base layer. Figure 3 As shown, in another arrangement, the inorganic fiber layer can be arranged close to the base layer. The arrangement method to be selected can be determined according to the specific application scenario.

[0039] Specifically, the adhesive layer can be made of an adhesive material, in which case the adhesive layer can be an adhesive film, which can be made of silicone rubber. Due to its adhesive properties, the adhesive layer mainly realizes the bonding between the structural layers. The inorganic fiber layer is made of an inorganic fiber material, for example, it can be made of inorganic fiber materials such as glass fiber and basalt fiber. The inorganic fiber layer will not cause galvanic corrosion with the base layer and the bonding layer, so that good isolation between the base layer and the bonding layer can be achieved, thereby reducing the galvanic corrosion phenomenon between the base layer and the bonding layer.

[0040] S102: Arranging a high-temperature tape layer on the base layer so that the high-temperature tape layer surrounds the bonding layer; wherein the working temperature of the high-temperature tape layer is greater than a preset temperature.

[0041] It should be understood that the size of the base layer is larger than the size of the bonding layer, the adhesive layer and the inorganic fiber layer, so that the projections of the three structural layers are all located within the base layer, and the outer edge of the base layer and the outer edges of the three structural layers are all at a certain distance, so that the high-temperature tape layer can be set. Moreover, in some application scenarios, the outer edges of the adhesive layer and the inorganic fiber layer do not exceed the outer edge of the bonding layer. When the high-temperature tape layer is set on the base layer, for the specific setting method of the high-temperature tape layer, the high-temperature tape layer needs to surround the bonding layer.

[0042] Figure 4 It is a top view of a configuration of a base layer, a laminating layer, an adhesive layer and an inorganic fiber layer.

[0043] Combination Figure 4 From another perspective, the adhesive layer, the inorganic fiber layer and the bonding layer form a combination, and the high-temperature tape layer is arranged around the bonding layer, that is, the high-temperature tape layer is arranged around the combination.

[0044] The working temperature of the high temperature tape layer is greater than the preset temperature, that is, the high temperature tape layer can withstand the preset temperature and can ensure normal performance at the preset temperature. The preset temperature may be 160° C., but is not limited thereto.

[0045] S103: Forming a composite layer structure by a compression molding process using the base layer, the laminating layer, the adhesive layer and the inorganic fiber layer.

[0046] In the above steps, when the base layer, the laminating layer, the adhesive layer and the inorganic fiber layer form a preliminary integrated structure, the connections between the various structural layers are not tight. This step compresses the preliminary formed integrated structure through a compression molding process to form a tight integrated structure, i.e., a composite layer structural part. Of course, in other embodiments, the composite layer structural part can be formed by a molding method such as vacuum bag molding.

[0047] In the process of forming the composite structural part by the compression molding process, the compression molding can be performed by a relevant mold, thereby ensuring the stability of the shape of each structural layer during the molding process. During the compression molding process, there will be a relatively high temperature, for example, it may be around 160°C, so in one embodiment, the preset temperature can be set to 160°C.

[0048] During the die-casting process, the bonding layer formed by the composite material usually flows out resin. If the flowing resin flows to the base layer, it will adhere to the base layer. The resin attached to the surface of the base layer will affect the electrophoresis effect of the subsequent process, and then affect the anti-corrosion effect of the composite layer structure. In this embodiment, a high-temperature tape layer is arranged around the bonding layer, and most of the resin flowing out of the bonding layer can flow onto the high-temperature tape layer. In the subsequent process, the high-temperature tape layer is directly removed and then electrophoresis is performed. That is, after this step, the high-temperature tape layer can be removed, and then electrophoresis can be performed, which can reduce the impact caused by the flowing resin, thereby ensuring that the composite layer structure has a good anti-corrosion effect.

[0049] In summary, based on the molding method of the composite layer structure provided by the above embodiment, on the one hand, an inorganic fiber layer is arranged between the base layer and the bonding layer, which can well isolate the base layer and the inorganic fiber layer, thereby reducing the galvanic corrosion between the base layer and the bonding layer, so as to improve the anti-corrosion effect of the composite layer structure. On the other hand, a high-temperature tape layer is arranged around the bonding layer, which can reduce the influence of the resin flowing out during the die-casting process on the electrophoresis, thereby improving the anti-corrosion effect of the composite layer structure.

[0050] Figure 5 It is a schematic flow chart of another embodiment of the molding method of the composite layer structure provided in the present application.

[0051] Combination Figure 5 In some specific embodiments, the step of laminating an adhesive layer and an inorganic fiber layer between the base layer and the laminating layer includes:

[0052] S201: Setting a first inorganic fiber patch; wherein the first inorganic fiber patch corresponds to the first through hole one by one, and the inorganic fiber patch can cover the first through hole corresponding thereto.

[0053] It should be understood that during the forming process of the base layer, the base layer will be provided with a first through hole, that is, the base layer is prefabricated with a first through hole. The number of the first through holes can be multiple, and the shapes or sizes corresponding to different first through holes can be different. Among them, the first through hole is used to facilitate the setting of subsequent structures, or the passage of subsequent wiring harnesses, etc.

[0054] The first inorganic fiber patch is made of the above-mentioned inorganic fiber material. The number of the first inorganic fiber patches is the same as the number of the first through holes, so that one first inorganic fiber patch corresponds to one first through hole, and the first inorganic fiber patch can cover the corresponding first through hole. The size of the first inorganic fiber patch does not need to be set larger, and can cover the first through hole with a certain margin.

[0055] S202: stacking the first inorganic fiber patch and the adhesive layer between the base layer and the laminating layer, and making the first inorganic fiber patch cover the first through hole corresponding thereto, so that all the first inorganic fiber patches constitute an inorganic fiber layer.

[0056] In this embodiment, the inorganic fiber layer is composed of all the first inorganic fiber patches, and one first inorganic fiber patch constitutes a part of the inorganic fiber layer. The arrangement of the first inorganic fiber patch and the adhesive layer can refer to the arrangement of the inorganic fiber layer and the adhesive layer described above. When there are multiple first inorganic fiber patches, since the multiple first inorganic fiber patches correspond to the multiple first through holes respectively, the multiple first inorganic fiber patches generally do not contact each other.

[0057] It should be understood that galvanic corrosion is likely to occur between the base layer and the bonding layer at the location of the first through hole. In this embodiment, the first inorganic fiber patch is arranged at the location of the first through hole, which can effectively reduce the galvanic corrosion at the first through hole. At this time, the bonding layer is other than the area opposite to the first through hole, and the inorganic fiber layer is not required to be arranged in other areas.

[0058] Based on this embodiment, an inorganic fiber layer is disposed in the area of ​​the first through hole where galvanic corrosion is more serious, but not in other areas. This can ensure a better anti-corrosion effect on the one hand, and reduce the number of inorganic fiber layers on the other hand, thereby reducing costs.

[0059] In other embodiments, an inorganic fiber layer having the same shape and size as the bonding layer may be provided to achieve full coverage of the bonding layer to achieve a better anti-corrosion effect, but at a slightly higher cost.

[0060] Figure 6 It is a schematic flow chart of another embodiment of the molding method of the composite layer structure provided in the present application.

[0061] Combination Figure 6 Based on the above embodiments, in some specific embodiments, the step of laminating an adhesive layer and an inorganic fiber layer between the base layer and the laminating layer further includes:

[0062] S301: Arrange a second inorganic fiber patch; wherein the second inorganic fiber patch corresponds to the shape and size of the peripheral edge area of ​​the bonding layer.

[0063] On the basis of the above embodiment, a second inorganic fiber patch is further provided. The peripheral edge area of ​​the bonding layer and the base layer are also prone to galvanic corrosion, so in this embodiment, a second inorganic fiber patch corresponding to the peripheral edge area of ​​the bonding layer is provided.

[0064] Specifically, the surrounding edge areas of the bonding layer can be set according to actual conditions, and different bonding layer sizes and application scenarios can correspond to different surrounding edge areas. The second inorganic fiber patch corresponds to the shape and size of the surrounding edge areas, and the shape of the second inorganic fiber patch can be the same as the shape of the surrounding edge areas, but the size of the second inorganic fiber patch is larger than the size of the surrounding edge areas.

[0065] Figure 7 This is an example diagram of the edge area around the bonding layer.

[0066] Combination Figure 7 , 11 is the outer edge of the bonding layer, 12 is the inner edge of the surrounding edge area of ​​the bonding layer, and the area between 11 and 12 is the surrounding edge area of ​​the bonding layer. Figure 7 The laminating layer is shown as a rectangle, and the corresponding surrounding edge areas are arranged in a manner that is illustrative only, and are not limited thereto in other embodiments.

[0067] S302: stacking a second inorganic fiber patch and an adhesive layer between the base layer and the laminating layer, and making the second inorganic fiber patch face the peripheral edge areas of the laminating layer.

[0068] After the second inorganic fiber patch is arranged, the second inorganic fiber patch and the adhesive layer are arranged between the base layer and the bonding layer. At this time, the first inorganic fiber patch and the second inorganic fiber patch together constitute the inorganic fiber layer, and the first inorganic fiber patch and the second inorganic fiber patch are both part of the inorganic fiber layer. Among them, when the second inorganic fiber patch is facing the edges of the bonding layer, on the one hand, the second inorganic fiber patch faces the edge area of ​​the bonding layer, and on the other hand, the edge area of ​​the patch layer faces the area facing the base layer and the second inorganic fiber patch.

[0069] In combination with the above content, if the embodiment of setting the first inorganic fiber patch is combined with the embodiment of setting the second inorganic fiber patch, then the above steps are: stack the first inorganic fiber patch, the second inorganic fiber patch and the adhesive layer between the base layer and the bonding layer, and make the first inorganic fiber patch cover the first through hole corresponding to it, so that the second inorganic fiber patch is opposite to the surrounding edge areas of the bonding layer, so that all the first inorganic fiber patches and the second inorganic fiber patches constitute an inorganic fiber layer.

[0070] Based on this embodiment, the anti-corrosion effect between the base layer and the bonding layer is further enhanced by providing the second inorganic fiber patch, and there is no need to provide an inorganic fiber layer with the same size as the bonding layer, thereby saving materials and reducing costs.

[0071] In combination with the above content, in some specific embodiments, the step of providing the first inorganic fiber patch includes:

[0072] A first inorganic fiber patch is arranged corresponding to each first through hole so that the shape of the first inorganic fiber patch is the same as the shape of the corresponding first through hole and the size of the first inorganic fiber patch is larger than the size of the corresponding first through hole.

[0073] It should be understood that in order to cover the first through hole, the shape of the first inorganic fiber patch is the same as the shape of the first through hole. For example, when the shape of the first through hole is rectangular, the corresponding shape of the first inorganic fiber patch is rectangular; when the shape of the first through hole is circular, the corresponding shape of the first inorganic fiber patch is circular. At this time, the size of the first inorganic fiber patch is set larger than the shape of the first through hole, so that the first inorganic fiber patch can cover the first through hole.

[0074] In some application scenarios, the first inorganic fiber patch should be neither too large nor too small. For example, the distance between the outer edge of the first inorganic fiber patch and the outer edge of the first through hole needs to be greater than the first distance and less than the second distance, thereby ensuring the anti-corrosion effect while saving materials.

[0075] Figure 8 It is a schematic flow chart of another embodiment of the molding method of the composite layer structure provided in the present application.

[0076] Combination Figure 8 In some specific embodiments, before the step of forming the composite layer structure by the molding process of the base layer, the laminating layer, the adhesive layer and the inorganic fiber layer, that is, before the above step S103, the process includes:

[0077] S401: second through holes are provided on the bonding layer, one-to-one with the first through holes.

[0078] In order to facilitate the setting of the structure and the passage of the wire harness, a through hole, namely a second through hole, is also required to be provided on the bonding layer. The second through hole corresponds to the first through hole one by one, and the second through hole can be arranged directly opposite to the corresponding first through hole. Since the distance between the bonding layer and the base layer is actually very small, the shape and size of the first through hole and the second through hole can be the same.

[0079] It should be understood that before the die-casting process is performed, only the bonding layer is punched to form the second through hole, and the adhesive layer and the inorganic fiber layer are not punched.

[0080] In combination with the above content, the first inorganic fiber patch can cover the first through hole, that is, the first inorganic fiber patch can cover the second through hole.

[0081] After the step of forming the composite layer structure by the molding process of the base layer, the laminating layer, the bonding layer and the inorganic fiber layer, that is, after the above step S103, the method includes:

[0082] S402: performing electrophoresis treatment on the composite layer structure.

[0083] After the composite layer structure is formed, electrophoresis treatment is further performed to improve the anti-corrosion effect of the composite layer structure. In combination with the above embodiment, before electrophoresis, the high temperature tape layer needs to be removed.

[0084] S403: Disposing avoidance holes on the adhesive layer and the inorganic fiber layer, which are opposite to the first through holes and the second through holes.

[0085] After the electrophoresis treatment is completed, the inorganic fiber layer and the adhesive layer are further punched to form avoidance holes, wherein the avoidance holes may have the same shape and size as the first through hole and the second through hole.

[0086] It should be understood that in this step, only the bonding layer is punched before the die-casting process, so that when the composite layer structure is subjected to electrophoresis, there is an adhesive layer and an inorganic fiber layer between the first through hole and the second through hole, so that it is not easy for the base layer and the bonding layer to react during the electrophoresis process, thereby ensuring that the composite layer structure has good performance.

[0087] Fig. 9 It is a schematic flow chart of another embodiment of the molding method of the composite layer structure provided in the present application.

[0088] Combination Fig. 9 In some specific embodiments, after the step of forming the composite layer structure by the molding process of the base layer, the laminating layer, the adhesive layer and the inorganic fiber layer, that is, after the above step S103, the method includes:

[0089] S501: performing electrophoresis treatment on the composite layer structure.

[0090] This embodiment provides another punching method for the laminating layer, the adhesive layer and the inorganic fiber layer, that is, no punching process is performed before the die-casting process.

[0091] S502: forming a second through hole opposite to the first through hole on the laminating layer, and providing an avoidance hole opposite to the first through hole and the second through hole on the adhesive layer and the inorganic fiber layer.

[0092] After the electrophoresis treatment is completed, a second through hole is further formed in the bonding layer, and an avoidance hole is formed in the adhesive layer and the inorganic fiber layer.

[0093] Similarly, in this embodiment, the second through hole and the avoidance hole are formed after the electrophoresis is completed. During the electrophoresis process, there is no situation where the first through hole and the second through hole are connected. Therefore, the electrophoresis process will not cause related reactions in the composite layer structure to reduce its performance.

[0094] Fig.10It is a schematic flow chart of another embodiment of the molding method of the composite layer structure provided in the present application.

[0095] Combination Fig.10 In some specific embodiments, before the step of providing a high temperature tape layer on the base layer so that the high temperature tape layer surrounds the bonding layer, that is, before the above step S102, the method includes:

[0096] S601: Obtain the size of the laminating layer and the distance between the outer edge of the laminating layer and the outer edge of the base layer.

[0097] It should be understood that the size of the bonding layer can reflect the possible situation of resin outflow during the die-casting process. The distance between the outer edge of the bonding layer and the outer edge of the base layer reflects the area where the high-temperature tape layer can be arranged and the operable area.

[0098] S602: Determine a target width of the high-temperature tape layer after it is formed according to the size and spacing of the bonding layer; wherein the target width is greater than a preset width.

[0099] In some application scenarios, when the size of the bonding layer is large, the target width of the high-temperature tape layer can be set larger. When the spacing is large, the target width can also be set larger. When the spacing is small, in order to avoid the high-temperature tape layer exceeding the edge of the base layer and facilitate setting, the target width can be set smaller.

[0100] In this embodiment, the target width is set to be larger than the preset width, which can ensure that the target width is not too small, thereby ensuring that it has a good effect of receiving the outflowing resin, thereby preventing a large amount of resin from flowing onto the base layer. In order to ensure that the high-temperature tape layer and the bonding layer are relatively close to ensure a good effect of receiving the resin, the distance between the orthographic projection of the outer edge of the bonding layer on the base layer and the edge of the high-temperature tape layer can be made smaller than the preset distance.

[0101] In some specific application scenarios, the preset distance can be set to ≤1mm, the target width of the high temperature tape layer can be set to 10mm-100mm, and the thickness can be set to 0.1mm-0.2mm.
