DETAILED DESCRIPTION

[0033] Example 1

[0034] The present embodiment provides a method for processing a fiber composite board. The fiber composite board is a carbon fiber composite board. First, an upper carbon fiber panel and a lower carbon fiber panel are processed and prepared. The processing and manufacturing methods of the upper carbon fiber panel and the lower carbon fiber panel are the same. A matrix resin film is transported above the carbon fiber plane fabric, and a matrix resin film is transported below the carbon fiber plane fabric. After the carbon fiber plane fabric and the matrix resin films above and below it are in place, a layered structure is pressed by hot pressing to form a carbon fiber panel.

[0035] In this embodiment, the base resin film is formed by stacking two layers of polyethylene resin films, and the thickness of the single layer of polyethylene resin film is 0.05 mm.

[0036] Carbon fiber flat fabric adopts single-layer plain weave.

[0037] The carbon fiber flat fabric and the matrix resin films above and below it are fed into a hot pressing device and hot pressed into layers. In this embodiment, the hot pressing pressure is 3 MPa and the hot pressing temperature is 150°C.

[0038] Through the hot pressing process, the upper and lower carbon fiber panels with a width of 1200mm are formed.

[0039] After the upper carbon fiber panel and the lower carbon fiber panel are formed, a core material with a width of 1200mm, a length of 200mm and a thickness of 5mm is fed between the upper carbon fiber panel and the lower carbon fiber panel, and the filling frequency is 5 times / min. In this embodiment, the core material is made of PM I foam, and an upper film adhesive is introduced between the core material and the upper carbon fiber panel, and a lower film adhesive is introduced between the core material and the lower carbon fiber panel. In this embodiment, the upper film adhesive and the lower film adhesive are both formed by stacking 2 layers of polyethylene adhesive film with a thickness of 0.02mm, forming a five-layer disc spring structure of a carbon fiber upper panel, an upper film adhesive, a core material, a lower film adhesive, and a carbon fiber lower panel. The five-layer stacked structure is pressed into a layered structure using a hot pressing process to finally form a carbon fiber composite sheet. In this embodiment, the hot pressing process hot pressing pressure of the five-layer stacked structure is 1Mpa, and the hot pressing temperature is 120°C.

[0040] Example 2

[0041] The present embodiment provides a method for processing a fiber composite board, wherein the fiber composite board is a carbon fiber composite board. Compared with Embodiment 1, the difference lies in that when the carbon fiber upper panel and the carbon fiber lower panel are prepared, the matrix resin film is formed by stacking two layers of polypropylene resin film, the thickness of the single-side polypropylene resin film is 0.1 mm, and the carbon fiber plane fabric is formed by stacking two layers of twill fabric. When the carbon fiber upper panel and the carbon fiber lower panel are hot pressed, the hot pressing pressure is 5 MPa and the hot pressing temperature is 230°C, so as to form a carbon fiber upper panel and a carbon fiber lower panel with a width of 1600 mm.

[0042] The corresponding core material used has a width of 1600mm, a length of 2000mm, and a thickness of 3mm. The filling frequency of the core material is 10 times / min. An upper film adhesive is introduced between the carbon fiber upper panel and the core material. The upper film adhesive is formed by stacking four layers of 0.04mm thick polypropylene adhesive film. A lower film adhesive is introduced between the carbon fiber lower panel and the core material. The lower film adhesive is formed by stacking four layers of 0.04mm thick polypropylene adhesive film.

[0043] When the formed five-layer laminated structure is hot-pressed, the hot-pressing pressure is 2 MPa and the hot-pressing temperature is 200° C. The remaining process methods are the same as those in Example 1 and will not be described in detail here.

[0044] Example 3

[0045] The present embodiment provides a method for processing a fiber composite board, wherein the fiber composite board is a carbon fiber composite board. Compared with Embodiment 1, the difference lies in that when the carbon fiber upper panel and the carbon fiber lower panel are prepared, the matrix resin film is formed by stacking two layers of polyamide resin film, and the thickness of the single-layer polyamide resin film is 0.06 mm. The carbon fiber plane fabric is formed by stacking two layers of satin fabric. When the carbon fiber plane fabric and the matrix resin film are hot-pressed, the pressure is 6 MPa and the hot-pressing temperature is 280°C, so as to form a carbon fiber upper panel and a carbon fiber lower panel with a width of 1000 mm.

[0046] Correspondingly, the core material has a width of 1000mm, a length of 1000mm, and a thickness of 5mm. It is fed between the carbon fiber upper panel and the carbon fiber lower panel at a transmission filling frequency of 6 times / min. The upper film adhesive introduced between the carbon fiber upper panel and the core material is composed of two layers of polyamide adhesive film with a thickness of 0.01mm stacked together. The lower film adhesive introduced between the carbon fiber lower panel and the core material is composed of two layers of polyamide adhesive film with a thickness of 0.01mm stacked together. When the five-layer laminated structure is hot pressed, the hot pressing pressure is 4Mpa and the hot pressing temperature is 260°C. The remaining methods are the same as in Example 1 and are not repeated here.

[0047] Example 4

[0048] The present embodiment provides a method for processing a fiber composite board, wherein the fiber composite board is a carbon fiber composite board. Compared with Embodiment 1, the difference lies in that when the carbon fiber upper panel and the carbon fiber lower panel are prepared, the matrix resin film is formed by stacking two layers of PET resin film, the thickness of the single-layer PET resin film is 0.08 mm, and the carbon fiber plane fabric is formed by stacking 12 layers of plain fabric. When the carbon fiber upper panel and the carbon fiber lower panel are hot-pressed, the pressure is 10 MPa and the hot-pressing temperature is 260°C, so as to form a carbon fiber upper panel and a carbon fiber lower panel with a width of 1200 mm.

[0049] Correspondingly, the core material has a width of 1200 mm, a length of 1600 mm, and a thickness of 5 mm, and is fed between the carbon fiber upper panel and the carbon fiber lower panel at a transmission filling frequency of 7 times / min.

[0050] The upper film adhesive and the lower film adhesive are both made of a single layer of PET adhesive film with a thickness of 0.04 mm. When the five-layer laminated structure is hot-pressed, the pressure is 5 MPa and the hot-pressing temperature is 250°C.

[0051] Using the processing method of the above embodiment, the core material, the upper film adhesive, the lower film adhesive, the carbon fiber upper panel and the carbon fiber lower panel are all prefabricated board structures. Compared with the method of extruding layer materials using molten materials, the material distribution of each layer is even, which improves the molding quality of the fiber composite board.

[0053] This embodiment provides a fiber composite board, which is processed by the processing method described in Embodiment 1 or Embodiment 2 or Embodiment 3 or Embodiment 4.

[0054] Example 6

[0055] This embodiment provides a fiber composite board processing device, such as Figure 1 As shown, it includes a fiber upper panel processing mechanism 1 and a fiber lower panel processing mechanism 2 which are arranged side by side. The fiber upper panel processing mechanism 1 is used to output a carbon fiber upper panel 10, and the fiber lower panel processing mechanism 2 is used to output a carbon fiber lower panel 11.

[0056] An upper film adhesive roller 8 is provided at the rear of the fiber upper panel processing mechanism 1, and the position of the upper film adhesive roller 8 is located below the movement trajectory of the carbon fiber upper panel 10 output by the fiber upper panel processing mechanism so that the output upper film adhesive 12 is located below the carbon fiber upper panel 10.

[0057] A lower layer film adhesive roller 13 is provided at the rear of the fiber lower panel processing mechanism 2, and the position of the lower layer film adhesive roller 13 is located above the movement trajectory of the carbon fiber lower panel 11 output by the fiber lower panel processing mechanism so that the output lower layer film adhesive 14 is located above the carbon fiber lower panel 11.

[0058] The structures of the fiber upper panel processing mechanism and the fiber lower panel processing mechanism are exactly the same, both of which include a fiber fabric roller 6 and a matrix resin film roller 5 located on both sides of the fiber fabric roller 6. The fiber fabric roller 6 and the matrix resin film roller 5 are both rotatably connected to the bracket. The fiber fabric roller 6 is used to wind the carbon fiber plane fabric 15, and the matrix resin film roller 5 is used to wind the matrix resin film 16.

[0059] A first hot pressing component 7 is arranged behind the fiber fabric roll 6 and the base resin film roll 5. The first hot pressing component 7 adopts existing hot pressing equipment and has two electrically heated hot pressing plates that can move toward or away from each other. Existing equipment can be used and its specific structure will not be described in detail here.

[0060] A first pair of rollers 4 is provided in front of the first hot pressing component 7. The first pair of rollers 4 includes two squeezing rollers rotatably connected to a bracket. The squeezing rollers are rotatably connected to the bracket. The two squeezing rollers form a space for the base resin film 16 and the fiber plane fabric 15 to pass through. The base resin film 16 and the fiber plane fabric 15 are squeezed by the first pair of rollers 4 to facilitate entering the space between the two electrically heated hot pressing plates of the first hot pressing component 7.

[0061] A tensioning roller 17 is provided between the first pair of roller mechanisms 4 and the fiber fabric winding roller 6 and the matrix resin film winding roller 5. The tensioning roller 17 is used to contact and tension the corresponding fiber plane fabric 15 and matrix resin film 16. The tensioning roller 17 is rotatably connected to the bracket.

[0062] A guide roller assembly is provided at the rear of the first hot pressing component 7, through which the distance between the carbon fiber upper panel 10 and the carbon fiber lower panel 11 is shortened, making it convenient for the carbon fiber upper panel 10 and the carbon fiber lower panel 11 to enter the rear second hot pressing component 9.

[0063] The guide roller assembly includes a first guide roller 18 and a second guide roller 19 located behind the first guide roller 18. The distance between the two first guide rollers 18 is greater than the distance between the two second guide rollers 19. The first guide roller 18 is used to contact the mutually close board surfaces of the two output carbon fiber panels, and the second guide roller 19 is used to contact the mutually distant board surfaces of the two output carbon fiber panels, thereby realizing the change of the movement trajectory of the two carbon fiber panels.

[0064] A second pair of rollers 20 are provided behind the upper film adhesive roll 8 and the lower film adhesive roll 13. The second pair of rollers 20 includes two squeezing rollers, and a space for the film adhesive to pass through is formed between the two squeezing rollers. The distance between the two second pair of rollers 20 is smaller than the distance between the two film adhesive rolls so that the distance between the upper film adhesive 12 and the lower film adhesive 14 is reduced after passing through the second pair of rollers 20, so as to facilitate entering the space between the two electrically heated pressing plates of the second hot pressing component 9.

[0065] A second hot pressing component 9 is disposed behind the guide roller group and the second pair of roller mechanisms 20. The second hot pressing component 9 may be an existing hot pressing device, and its specific structure will not be described in detail herein.

[0066] A core material pushing mechanism 3 is provided in front of or on one side of the second hot pressing component 9 . The core material pushing mechanism 3 is used to push the pre-prepared core material 21 between the upper film adhesive 12 and the lower film adhesive 14 .

[0067] Preferably, the core material pushing mechanism 3 adopts a synchronous belt transmission mechanism or a roller mechanism or other equipment capable of outputting linear motion, which will not be described in detail here.

[0068] When a synchronous belt conveying mechanism is adopted, the core material pushing mechanism is arranged on one side or in front of the second hot pressing component; when a pair of roller mechanisms is adopted, the core material pushing mechanism is arranged in front of the second hot pressing component.

[0069] A pulling mechanism is disposed at the rear of the second hot pressing component 9, and the pulling mechanism is used to pull the formed fiber composite board, thereby driving the fiber plane fabric, matrix resin film, and film adhesive in the front to be transported forward.

[0070] Furthermore, the pulling mechanism adopts a third pair of roller mechanisms 22, including two transmission rollers, and a space for the fiber composite board to pass through is formed between the two transmission rollers, wherein at least one transmission roller is connected to a power mechanism, and the power mechanism adopts a motor, which can drive the transmission roller to rotate, thereby driving the movement of the fiber composite board through friction.

[0071] Example 7

[0072] This embodiment provides a working method of the fiber composite board processing device described in Embodiment 6:

[0073] The third pair of roller mechanisms 22 works to drive the formed fiber composite sheet to move, thereby driving the fiber plane fabric, matrix resin film, and film adhesive in front of it to move forward; the fiber fabric roller rotates to release the fiber plane fabric; the matrix resin film roller rotates to release the matrix resin film; the upper film adhesive roller and the lower film adhesive roller rotate to release the film adhesive.

[0074] When the matrix resin film and the fiber plane fabric are transported to the first hot pressing component, the first hot pressing component works to prepare the carbon fiber upper panel and the carbon fiber lower panel by hot pressing, and the carbon fiber upper panel and the carbon fiber lower panel continue to enter the second hot pressing component driven by the pulling mechanism, and the core material pushing mechanism delivers the core material into the space between the upper film adhesive and the lower film adhesive at a set filling frequency, and the second hot pressing component hot presses the carbon fiber upper panel, the upper film adhesive, the core material, the lower film adhesive and the carbon fiber lower panel, thereby completing the processing of the carbon fiber composite sheet.

[0075] By adopting the processing device and working method of this embodiment, each roller releases the corresponding layer structure of the composite board through the driving of the traction mechanism, and then the multiple layer structures are hot-pressed into shape using the hot pressing components. The entire processing process can be carried out continuously, effectively improving the overall processing efficiency of the fiber composite board and the stability of the product.
