Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] See Figures 1 to 2 The fiberglass component 10 provided in this embodiment of the invention includes a core material board 15 and a reinforcing layer covering the core material board 15. The reinforcing layer includes a first panel 11, a second panel 12, and two first side panels 13. The first panel 11 and the second panel 12 are arranged opposite to each other and clamp the core material board 15 from both sides. The two first side panels 13 clamp the core material board 15 from both sides and are respectively connected to the first panel 11 and the second panel 12. The first panel 11 has a plurality of first openings 119 arranged sequentially in a first direction on one side edge facing the first side panel 13. The core material board 15 has a plurality of second openings 151 arranged sequentially in a first direction on one side edge facing the first side panel 13. The first side panel 13 has a first connecting hole 131. The first openings 119, the second openings 151, and the first connecting hole 131 are connected. The first connecting hole 131 is used to connect other fiberglass components 10.

[0023] The first connecting hole 131 can be a threaded hole.

[0024] In this embodiment of the invention, the reinforcing layer includes two second side plates 14, which clamp the core material plate 15 from both sides. The second side plates 14 are respectively connected to the first panel 11 and the second panel 12. The first panel 11 has a plurality of third openings 118 arranged sequentially in a second direction on one side edge facing the second side plate 14. The core material plate 15 has a fourth opening 152 arranged sequentially in a second direction on one side edge facing the second side plate 14. The second side plate 14 has a second connecting hole 141. The third openings 118, the fourth openings 152 and the second connecting hole 141 are connected.

[0025] Specifically, the second panel 12 is a rectangular panel. The first direction is the extension direction of the short side of the second panel 12, and the second direction is the extension direction of the long side of the second panel 12. The first direction is perpendicular to the second direction.

[0026] In this embodiment of the invention, the core material board 15 has a plurality of spaced-apart first through holes, and the reinforcing layer includes a plurality of spaced-apart first reinforcing members 111. The first reinforcing members 111 are located inside the first through holes, and their two ends are respectively connected to the surfaces of the first panel 11 and the second panel 12 facing each other. The first panel 11, the second panel 12, the two first side plates 13, and the first reinforcing members 111 are integrally formed. The first reinforcing members 111 can be cylindrical, square, or other shapes, depending on the specific circumstances; this invention does not impose any limitations on this.

[0027] A first through hole extends from one side of the core material board 15 to the other side of the core material board 15. Multiple first through holes are spaced apart on the core material board 15. The core material board 15 can be polyurethane foam or other materials. For example, the core material board 15 may be a foam core material with a density of 0.1 g / cm³.

[0028] Among them, the core material board 15 is a cuboid board, and the outer contour of the fiberglass component 10 is a cuboid.

[0029] In this embodiment of the invention, the reinforcing layer includes a plurality of spaced-apart second reinforcing members 112, which are located on the sidewall of the second opening 151. Providing the second reinforcing members 112 on the sidewall of the second opening 151 increases the load-bearing capacity of the opening and prevents damage.

[0030] In this embodiment of the invention, the reinforcing layer includes a plurality of third reinforcing members 113, which connect the two ends of two adjacent first reinforcing members 111. The reinforcing layer is integrally formed.

[0031] In this embodiment of the invention, the reinforcing layer comprises a porous reinforcing material and a resin mixture cured inside the porous reinforcing material, the resin mixture comprising resin. The reinforcing layer comprises a first panel 11, a second panel 12, two first side panels 13, two second side panels 14, a first reinforcing member 111, a second reinforcing member 112, and a third reinforcing member 113, all integrally formed. The reinforcing layer encapsulates the core material board 15 and fills the first through-hole.

[0032] In this embodiment of the invention, the resin mixture includes an acrylic-modified vinyl resin and a diluent.

[0033] In one specific embodiment, the resin mixture comprises 100 parts by mass of acrylic-modified vinyl resin and 5-10 parts by mass of diluent. The diluent may be styrene.

[0034] Furthermore, the resin mixture includes acrylic-modified vinyl resin, ultraviolet absorber, light stabilizer, leveling agent, defoamer, additives, accelerator, curing agent, and diluent. The diluent is styrene, the additive is an anti-aging agent, the accelerator is a cobalt salt accelerator, and the curing agent is methyl ethyl ketone peroxide.

[0035] Furthermore, the present invention also provides a method for preparing fiberglass components, such as... Figure 3 As shown, the preparation method of fiberglass components includes: 301. Prepare the core material board, lay porous reinforcing material on the surface of the core material board to cover the core material board, and place the covered core material board on the processing board.

[0036] The core material board has multiple spaced-apart first through holes.

[0037] In one specific embodiment, a first through-hole extends from one side of the core material board to the other side surface of the core material board. Multiple first through-holes are spaced apart in the core material board.

[0038] In one specific embodiment, a foam core material with a density of 0.1 g / cm³ is selected as the core material board, and a first through hole is opened inside the core material board according to design requirements. The surface of the core material board and the inner wall of the first through hole are wiped with anhydrous ethanol to remove impurities, and then placed in a drying oven at 60 degrees Celsius for 2 hours. After being removed, it is cooled to room temperature for use.

[0039] In this embodiment of the invention, the porous reinforcing material is glass fiber. Glass fiber is a fibrous material made from glass as raw material through processes such as high-temperature melting, drawing, spinning, and weaving. The porous reinforcing material contains multiple interconnected pores, allowing liquid to flow into the interior of the porous reinforcing material and fill it.

[0040] In this embodiment of the invention, porous reinforcing material is laid in the first through hole of the core material board, and porous reinforcing material is laid on the surface of the core material board to cover the core material board, and the covered core material board is placed on the processing plate.

[0041] In one specific implementation, the first through-hole of the core material board is filled with flocculent glass fiber. Specifically, glass fiber yarn is laid inside the first through-hole of the core material board, and the glass fiber yarn is tightly adhered to the inner wall of the first through-hole to ensure no gaps.

[0042] In one specific embodiment, layers of glass fiber are laid on a processing board. Specifically, a layered glass fiber cloth is obtained, and multiple layers of glass fiber cloth are laid on the processing board. A core board is placed on the multiple layers of glass fiber cloth on the processing board, and multiple layers of glass fiber cloth are laid on the upper and side surfaces of the core board.

[0043] Furthermore, a resin mixture is coated between adjacent layers of fiberglass cloth. The resin mixture further ensures that the fiberglass cloth is impregnated with the resin mixture.

[0044] Furthermore, the porous reinforcing material laid on the surface of the core material board is an integral material. Specifically, multiple layers of pre-cut planar fiberglass cloth are obtained, folded to form a hollow cuboid, and then multiple layers of pre-cut planar fiberglass cloth are laid on a processing board. The core material board is placed on the planar fiberglass cloth on the processing board, and the pre-cut planar fiberglass cloth is folded to cover the upper and side surfaces of the core material board, thereby completely covering the core material board. By covering the core material board with an integrally formed fiberglass cloth, the strength of the fiberglass cloth can be improved.

[0045] Furthermore, placing the covered core material board onto the processing board includes: laying an insulating layer on the processing board; and placing the covered core material board onto the insulating layer on the processing board. Specifically, the processing board is laid flat, and an insulating layer is laid on the processing board.

[0046] The isolation layer consists of resin, color masterbatch, and release agent.

[0047] Furthermore, laying an isolation layer on the processing board includes: cleaning the surface of the processing board and then laying an isolation layer on the processing board.

[0048] In this embodiment of the invention, the processing plate can be a steel plate. The surface of the processing plate is treated with sandblasting to remove rust, followed by soaking in an alkaline degreasing agent for 10 minutes, rinsing thoroughly with clean water, and drying to complete the cleaning process. After cleaning, a vinyl ester resin-based release layer is evenly sprayed onto the upper surface of the steel plate, avoiding the formation of air bubbles during the spraying process. For example, the release layer thickness is 0.3 mm.

[0049] Furthermore, one side surface of the pre-cut planar fiberglass cloth is provided with multiple strip-shaped fiberglass cloths, which are integrally formed with the planar fiberglass cloth. Each strip-shaped fiberglass cloth corresponds to a first through hole. Multiple layers of pre-cut planar fiberglass cloth are laid on a processing plate. The core material board is placed on the fiberglass cloth on the processing plate, and the multiple strip-shaped fiberglass cloths are passed through the first through holes. The pre-cut planar fiberglass cloth is folded to cover the upper and side surfaces of the core material board, and one end of each strip-shaped fiberglass cloth is bonded to the planar fiberglass cloth. This completely covers the core material board, forming a single unit with the strip-shaped fiberglass cloth. By integrally forming the fiberglass cloth to cover the core material board, the strength of the fiberglass cloth can be improved.

[0050] 302. A flexible film layer is used to cover the core material board, and the flexible film layer and the processed board form a sealed space.

[0051] In this embodiment of the invention, the material of the flexible membrane layer can be ETFE (ethylene-tetrafluoroethylene copolymer membrane).

[0052] 303. Inject the resin mixture into the sealed space so that the resin mixture impregnates the core board and enters the pores in the porous reinforcement material.

[0053] Resin mixtures include resins.

[0054] Specifically, the sealed space is evacuated, and a resin mixture is injected into the sealed space so that the resin mixture impregnates the core material board and enters the pores in the porous reinforcing material.

[0055] In this embodiment of the invention, a vacuum treatment is performed on the sealed space, and a resin mixture is injected into the sealed space so that the resin mixture impregnates the core material board and enters the pores in the porous reinforcing material, including: (1) Vacuum the sealed space until the air pressure in the sealed space reaches the preset air pressure value.

[0056] Specifically, the sealed space is evacuated until the air pressure in the sealed space reaches the preset air pressure value, and the evacuation process continues for a preset time. This ensures that the gas is completely squeezed out.

[0057] The preset air pressure value is less than 0. Specifically, the preset air pressure value is between -0.05 MPa and -0.1 MPa. For example, the preset air pressure value is -0.08 kPa, and the preset duration is 30 minutes.

[0058] (2) Lift one side of the processing plate so that the processing plate is at a preset angle with the horizontal plane, evacuate the sealed space, and inject the resin mixture into the sealed space.

[0059] The preset angle can be between 30 and 60 degrees. For example, the preset angle is 45 degrees. You can set it according to the specific situation.

[0060] 304. The sealed space is cured to obtain the first fiberglass component.

[0061] In this embodiment of the invention, the temperature of the sealed space is adjusted to a preset temperature and then cured. The preset temperature is between 40 and 60 degrees Celsius. For example, the preset temperature is 50 degrees Celsius.

[0062] 305. Remove the first fiberglass component and perform post-processing to obtain the second fiberglass component.

[0063] Specifically, the flexible membrane layer is removed, the first fiberglass component is taken out and cut to a preset size to obtain the second fiberglass component.

[0064] The second fiberglass component includes a core board and a reinforcing layer that wraps the core board. The reinforcing layer includes a porous reinforcing material and a resin mixture cured inside the porous reinforcing material. The reinforcing layer fills a first through hole. The reinforcing layer includes a first panel, a second panel, and two first side panels. The first panel and the second panel are arranged opposite to each other. The first panel and the second panel clamp the core board from both sides. The two first side panels clamp the core board from both sides.

[0065] This invention utilizes a composite structure design of a core material, two layers of porous reinforcing materials, and a steel plate to create a double-layer lightweight structure, significantly improving the structural strength of the component under conditions of limited unit weight. The core material not only ensures the lightweight requirement but also forms a continuous reinforcement system with the porous reinforcing materials in the first through-hole, effectively enhancing the overall integrity of the component and avoiding the problem of interlayer delamination in traditional multi-layer components.

[0066] 306. Drill holes in the first panel, core board and first side plate of the second fiberglass component to obtain multiple first openings on the first panel, multiple second openings on the core board and first connecting holes on the first side plate.

[0067] The first opening, the second opening, and the first connecting hole are connected. The first connecting hole is used to connect other fiberglass components.

[0068] Specifically, holes are drilled simultaneously in the first panel and core board of the second fiberglass component to obtain multiple first openings in the first panel and multiple second openings in the core board. The first and second openings have the same cross-section, both being rectangular. Holes are drilled in the first side plate of the second fiberglass component to obtain first connecting holes. The cross-section of the first opening is larger than that of the first connecting hole. The first and second openings are used to insert bolts, thereby locking the two second fiberglass components together by passing the bolts through the first connecting holes.

[0069] See Figures 4-7 The present invention provides a pressurized chamber 20, which includes a plurality of fiberglass components 10. The plurality of fiberglass components 10 are spliced ​​together to form a hollow cavity. The fiberglass components 10 are any of the fiberglass components 10 mentioned above.

[0070] In this embodiment of the invention, the second panels 12 of the fiberglass components 10 are all rectangular, and the length of the second panel 12 in the second direction is greater than the length of the second panel 12 in the first direction. That is, the side of the second panel 12 in the second direction is the long side, and the side of the second panel 12 in the first direction is the short side. The multiple fiberglass components 10 include multiple top fiberglass components 21, multiple bottom fiberglass components 23, and multiple side fiberglass components 22. The long sides of the multiple top fiberglass components 21 are spliced ​​together, and the short sides of the top fiberglass components 21 are respectively connected to two opposite side fiberglass components 22. The top fiberglass components 21 include multiple top reinforcing members 114, which are distributed crisscrossingly. The intersection of two crisscrossing top reinforcing members 114 is connected to one end of a first reinforcing member 111. The multiple first reinforcing members 111 on the top fiberglass components 21 are arranged at intervals.

[0071] In this embodiment of the invention, the pressurized chamber 20 includes a plurality of L-shaped connectors 24. Each L-shaped connector 24 includes a first connecting plate and a second connecting plate that are connected to each other. The first connecting plate and the second connecting plate are perpendicular to each other. The first connecting plate and the second connecting plate are provided with a plurality of third connecting holes 241. The third connecting holes 241 on the first connecting plate are aligned with the first connecting holes 131 on the short side of the top fiberglass component 21 and are connected by bolts. The third connecting holes 241 on the second connecting plate are aligned with the first connecting holes 131 on the short side of the side fiberglass component 22 and are connected by bolts, thereby connecting the top fiberglass component 21 and the side fiberglass component 22.

[0072] Specifically, among the multiple top reinforcements 114, some of the top reinforcements 114 extend along a first direction, and some of the top reinforcements 114 extend along a second direction.

[0073] Furthermore, in the direction from the center to the edge of the core material board 15, the spacing between two adjacent top reinforcing members 114 gradually increases. For example, if the dimensions of the top fiberglass component 21 are 2100mm*800mm*100mm, the spacing between the two top reinforcing members 114 near the center of the core material board 15 can be 250mm to 300mm, and the spacing between the two top reinforcing members 114 away from the center of the core material board 15 can be 350mm to 400mm. This differentiated spacing of the top reinforcing members 114 in different areas can reduce material usage.

[0074] Furthermore, in the first panel 11 and the second panel 12 of the top fiberglass component 21, the first panel 11 is located between the second panel 12 and the bottom fiberglass component 23, and the first panel 11 is located below the second panel 12. The thickness of the first panel 11 is greater than the thickness of the second panel 12. For example, the thickness of the first panel 11 can be 3.5 to 4.5 mm, and the thickness of the second panel 12 can be 2 mm to 3 mm.

[0075] Furthermore, the thickness of the first panel 11 gradually decreases from the center to the edge, with the thickness of the first panel 11 in the central region being greater than that in the edge regions. For example, the thickness of the first panel 11 at the center is 4.5 mm, and the thickness of the first panel 11 at the edge is 3.5 mm. The thickness of the same panel can also vary in different regions according to the stress characteristics; the panel thickness can be relatively thicker in the central region where deformation is greater, and relatively thinner in the surrounding areas near the edges.

[0076] Furthermore, the surface of the first panel 11 away from the second panel 12 is flat, and the surface of the first panel 11 close to the second panel 12 protrudes towards the second panel 12, forming a convex arc surface.

[0077] In this embodiment of the invention, the long sides of multiple bottom fiberglass components 23 are spliced ​​together, and the short sides of the bottom fiberglass components 23 are respectively connected to two adjacent side fiberglass components 22. The bottom fiberglass component 23 includes multiple bottom reinforcing members 115. The two ends of the bottom reinforcing members 115 are respectively connected to one end of two adjacent first reinforcing members 111. Every six bottom reinforcing members 115 are connected end to end to form a hexagonal frame.

[0078] Specifically, every six bottom reinforcing members 115 are connected end to end to form a regular hexagonal frame.

[0079] In this embodiment of the invention, the long sides of multiple side fiberglass components 22 are spliced ​​together, and the short sides of the side fiberglass components 22 are respectively connected to the short sides of the top fiberglass component 21 and the bottom fiberglass component 23. Each side fiberglass component 22 includes multiple side reinforcing members 116, with both ends of each side reinforcing member 116 connected to two second side plates 14. The side reinforcing members 116 are connected to multiple first reinforcing members 111 located on the same straight line. All the side reinforcing members 116 extend along a first direction, and are arranged sequentially at intervals along a second direction. The multiple first reinforcing members 111 on the side fiberglass component 22 are arranged in an array.

[0080] Furthermore, since the side reinforcement 116 mainly bears a smaller surface load, the spacing between two adjacent side reinforcements 116 on the side fiberglass component 22 is smaller than the spacing between two adjacent top reinforcements 114 on the top fiberglass component 21, thereby reducing the amount of top reinforcements 114 used.

[0081] It should be noted that the top fiberglass component 21, the bottom fiberglass component 23, and the side fiberglass component 22 all include a core material board 15, a first panel 11, a second panel 12, two first side panels 13, two second side panels 14, a first reinforcing member 111, and a second reinforcing member 112.

[0082] The only differences between the top fiberglass component 21, the bottom fiberglass component 23, and the side fiberglass component 22 are the layout of the multiple top reinforcing members 114, the layout of the multiple bottom reinforcing members 115, the layout of the multiple side reinforcing members 116, the layout of the multiple first reinforcing members 111, and the thickness of the first panel 11 and the second panel 12.

[0083] The present invention has the following beneficial effects: 1. Lightweight and high strength synergistic: Through the composite structure design of "panel + reinforcing ribs + foam filling", the structural weight is reduced compared with the traditional single fiberglass structure without reducing the stiffness, effectively solving the problem of limited floor load-bearing capacity and expanding application scenarios.

[0084] 2. Significantly improved stiffness: The reinforcing ribs and rigid polyurethane foam form a synergistic support, resulting in a significantly improved moment of inertia compared to a single-layer structure. The deformation under internal pressure is controllable, ensuring the structural stability of the pressurized chamber.

[0085] 3. Integrated thermal insulation: The polyurethane foam filling layer serves both structural support and thermal insulation functions, significantly reducing the energy consumption of the pressurized cabin and eliminating the need for an additional insulation layer, thus simplifying the structural design.
