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 Figure 1 The fiberglass component 10 provided in this embodiment of the invention includes a core material board 11 and a reinforcing layer 112 that wraps around the core material board 11. The core material board 11 has a plurality of spaced-apart through holes 111. The reinforcing layer 112 fills the through holes 111. The reinforcing layer 112 includes a reinforcing material and a resin mixture cured inside the reinforcing material. The resin mixture includes resin. The reinforcing layer 112 wraps around the core material board 11 and fills the through holes 111.

[0023] In this embodiment of the invention, the through hole 111 extends from one side of the core material plate 11 to the other side surface of the core material plate 11.

[0024] In this embodiment of the invention, the cross-sectional shape of the through hole 111 is I-shaped, and the reinforcing layer 112 formed in the through hole 111 can have stronger bearing capacity at the end, thereby improving the strength of the fiberglass component 10.

[0025] The core material board 11 can be made of foam or other materials. For example, the core material board 11 can be made of foam core material with a density of 0.1 g / cm³.

[0026] The core material 11 is a cuboid plate, and the outer contour of the fiberglass component 10 is also cuboid. The reinforcing layer 112 includes a hollow cuboid cavity and multiple reinforcing ribs within the cuboid cavity, with the cuboid cavity and multiple reinforcing ribs integrally formed. The two ends of the reinforcing ribs are respectively connected to the inner wall of the cuboid cavity. The multiple reinforcing ribs and multiple through holes 111 correspond one-to-one.

[0027] In this embodiment of the invention, the resin mixture includes an acrylic-modified vinyl resin and a diluent.

[0028] 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.

[0029] 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.

[0030] Combination Figures 2 to 3 This invention also provides a fiberglass component manufacturing apparatus 20. The manufacturing apparatus 20 includes a processing platform 21, a mixture supply container 281, a feed pipe 282, a vacuum extraction device, a first suction pipe 291, and a flexible membrane layer 27. The mixture supply container 281 contains a liquid resin mixture. The processing platform 21 is provided with a processing plate 22, which is used to support the core material board 11. The flexible membrane layer 27 is used to enclose and form a sealed space with the processing plate 22. One end of the feed pipe 282 is connected to the mixture supply container 281, and the other end of the feed pipe 282 extends into the sealed space. One end of the first suction pipe 291 is connected to the vacuum extraction device, and the other end of the first suction pipe 291 extends into the sealed space. The vacuum extraction device is used to evacuate the sealed space. The mixture supply container 281 injects the resin mixture into the sealed space through the feed pipe 282.

[0031] In this embodiment of the invention, the vacuum extraction device includes a vacuum pump 294, a sealed mixture collection container 295, and a second suction pipe 293. One end of the first suction pipe 291 and the second suction pipe 293 are respectively inserted into the mixture collection container 295, and the other end of the second suction pipe 293 is connected to the vacuum pump 294. The vacuum pump 294 is used to evacuate the mixture collection container 295, thereby evacuating the sealed space.

[0032] The feed pipe 282 and the first exhaust pipe 291 are located on both sides of the core material plate 11.

[0033] In this embodiment of the invention, the processing plate 22 is rotatably connected to one side edge of the processing platform 21 with one side edge facing the feed pipe 282. The processing platform 21 is provided with a cylinder 23. One end of the cylinder 23 is rotatably connected to the bottom of the processing plate 22, and the other end of the cylinder 23 is rotatably connected to the top of the processing platform 21. The cylinder 23 is used to drive the processing plate 22 to rise away from the side edge of the feed pipe 282.

[0034] By controlling the cylinder 23 to drive the processing plate 22 to rise on the side away from the feed pipe 282, the end of the first suction pipe 291 that extends into the sealed space is higher than the end of the feed pipe 282 that extends into the sealed space. This raises the position of the first suction pipe 291, and the resin mixture can only flow out from the first suction pipe 291 after filling the entire sealed space. This allows the resin mixture to fully impregnate the core material board 11 and the glass fiber cloth that wraps the core material board 11.

[0035] Specifically, the processing plate 22 is connected to the processing platform 21 by a hinge 211 on one side edge facing the feed pipe 282. The processing platform 21 is provided with a support platform 212 on the other side edge. When the cylinder 23 is not extended, the support platform 212 supports the processing platform 21 and keeps the processing platform 21 in a horizontal state.

[0036] In this embodiment of the invention, the other end of the feed pipe 282 extends into the sealed space, and the other end of the feed pipe 282 is located between the flexible film layer 27 and the processing plate 22. The gap between the feed pipe 282, the flexible film layer 27 and the processing plate 22 is sealed with sealant.

[0037] The sealant used is a silicone-based sealant. Silicone-based sealants have excellent sealing properties, can tightly adhere to vacuum bags, lightweight steel plates, and fiberglass, and do not react with acrylic-modified vinyl ester resin or styrene thinner.

[0038] In this embodiment of the invention, a pressure gauge 292 is provided on the mixture collection container 295. The pressure gauge 292 is used to display the pressure in the mixture collection container 295 and can detect the pressure in the closed space.

[0039] Furthermore, a plurality of guide tubes 26 are provided between the flexible film layer 27 and the glass fiber cloth wrapping the core material board 11. The two ends of the guide tubes 26 are respectively facing the feed pipe 282 and the first exhaust pipe 291. The guide tubes 26 can guide the resin mixture from the feed pipe 282 side to the first exhaust pipe 291 to avoid the resin mixture from clogging.

[0040] Furthermore, the guide tube 26 has multiple openings on the side facing the core material board 11, which can guide the resin mixture to the glass fiber cloth on the upper surface of the core material board 11.

[0041] The present invention also provides a method for preparing fiberglass components. The fiberglass component 10 provided in the embodiments of the present invention is prepared by the method for preparing fiberglass components provided in the embodiments of the present invention.

[0042] Combination Figures 1-4 The methods for preparing fiberglass components include: 301. Prepare the core material board.

[0043] The core material board 11 has multiple through holes 111 spaced apart.

[0044] In one specific embodiment, the through hole 111 extends from one side of the core material plate 11 to the other side surface of the core material plate 11.

[0045] In one specific embodiment, the core material board 11 is selected from foam core material with a density of 0.1 g / cm³, and through holes 111 are opened inside the core material board 11 according to design requirements. The surface of the core material board 11 and the inner wall of the through holes 111 are wiped with anhydrous ethanol to remove impurities, and then placed in a drying oven at 60 degrees Celsius for 2 hours. After being taken out, it is cooled to room temperature for use.

[0046] 302. Lay reinforcing material in the through holes of the core material board.

[0047] In this embodiment of the invention, the 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 reinforcing material contains multiple interconnected pores, allowing liquid to flow into the interior of the reinforcing material and fill it.

[0048] In one specific implementation, the through holes 111 on the core material board 11 are filled with flocculent glass fibers. Specifically, glass fiber yarn is laid inside the through holes 111 of the core material board 11, and the glass fiber yarn is tightly fitted to the inner wall of the through holes 111 to ensure no gaps.

[0049] 303. Lay reinforcing material on the surface of the core board to cover the core board, and place the covered core board on the processing plate.

[0050] In one specific embodiment, layered glass fiber is laid on the processing plate 22 of the processing platform 21. Specifically, layered glass fiber cloth is obtained and multiple layers of glass fiber cloth are laid on the processing plate 22 of the processing platform. The core material board 11 is placed on the multiple layers of glass fiber cloth on the processing plate 22, and multiple layers of glass fiber cloth are laid on the upper surface and side surface of the core material board 11.

[0051] In one specific embodiment, the reinforcing material comprises a multilayered glass fiber cloth. The multilayered glass fiber cloth can be a fabric woven from glass fiber yarn using a textile machine. The glass fiber yarn is waterproof, and the fiberglass yarn is woven in both directions to form the multilayered glass fiber cloth. The multilayered glass fiber cloth has multiple pores, through which the resin mixture enters and impregnates the multilayered glass fiber cloth.

[0052] 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.

[0053] Furthermore, the reinforcing material laid on the surface of the core material board 11 is an integral material. Specifically, multiple layers of pre-cut planar fiberglass cloth are obtained, folded to form a hollow cuboid, and then laid on the processing plate 22 of the processing platform. The core material board 11 is placed on the planar fiberglass cloth on the processing plate 22, and the pre-cut planar fiberglass cloth is folded to cover the upper and side surfaces of the core material board 11, thereby completely covering the core material board 11. By covering the core material board 11 with an integrally formed fiberglass cloth, the strength of the fiberglass cloth can be improved.

[0054] Furthermore, placing the covered core material board 11 onto the processing plate 22 includes: laying an isolation layer 118 on the processing plate 22; and placing the covered core material board 11 onto the isolation layer 118 on the processing plate 22. Specifically, the processing plate 22 is laid flat, and the isolation layer 118 is laid on the processing plate 22.

[0055] The isolation layer 118 comprises resin, color masterbatch, and release agent.

[0056] Furthermore, laying an isolation layer 118 on the processing plate 22 includes: cleaning the surface of the processing plate 22 and then laying the isolation layer 118 on the processing plate 22.

[0057] In this embodiment of the invention, the processing plate 22 can be a steel plate. The surface of the processing plate 22 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 118 is uniformly sprayed onto the upper surface of the steel plate, avoiding the generation of air bubbles during the spraying process. For example, the release layer 118 has a spraying thickness of 0.3 mm.

[0058] Furthermore, one side surface of the pre-cut planar glass fiber cloth is provided with multiple strip-shaped glass fiber cloths, which are integrally formed with the planar glass fiber cloth. Each strip-shaped glass fiber cloth corresponds to a through hole 111. Multiple layers of pre-cut planar glass fiber are laid on the processing plate 22 of the processing platform 21. The core material board 11 is placed on the glass fiber cloth on the processing plate 22, and the multiple strip-shaped glass fiber cloths are passed through the through holes 111 respectively. The pre-cut planar glass fiber cloth is folded to cover the upper and side surfaces of the core material board 11, and one end of each strip-shaped glass fiber cloth is bonded to the planar glass fiber cloth. This completely covers the core material board 11, making the strip-shaped glass fiber cloth and the planar glass fiber a single unit. By wrapping the core material board 11 with an integrally formed glass fiber cloth, the strength of the glass fiber cloth can be improved.

[0059] 304. 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.

[0060] In this embodiment of the invention, the material of the flexible film layer 27 can be ETFE (ethylene-tetrafluoroethylene copolymer film).

[0061] 305. Vacuum treatment is applied to the sealed space, and a resin mixture is injected into the sealed space so that the resin mixture impregnates the core board and the reinforcing material.

[0062] The resin mixture includes resin.

[0063] 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 the reinforcing material, including: (1) Vacuum the sealed space until the air pressure in the sealed space reaches the preset air pressure value.

[0064] 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.

[0065] 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.

[0066] (2) Lift one side of the processing plate 22 so that the processing plate 22 is at a preset angle with the horizontal plane, evacuate the sealed space, and inject the resin mixture into the sealed space.

[0067] 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.

[0068] Combination Figure 2 and Figure 3 By controlling the cylinder 23 to drive the processing plate 22 to rise on the side away from the feed pipe 282, the end of the first suction pipe 291 that extends into the sealed space is higher than the end of the feed pipe 282 that extends into the sealed space, thereby raising the position of the first suction pipe 291, which allows the resin mixture to fully impregnate the core material plate 11 and the glass fiber cloth covering the core material plate 11.

[0069] Because the air pressure in the sealed space is low, the resin mixture in the mixture supply container 281 can be drawn into the sealed space, thus injecting the resin mixture into the sealed space. During the vacuum pump 294's continued evacuation process, the resin mixture in the sealed space flows out from the first evacuation pipe 291 and into the mixture collection container 295 after passing through the core material plate 11 and the reinforcing material.

[0070] In another embodiment, the preparation device 20 includes two cylinders 20, a processing platform 21, and a processing plate 22 arranged opposite to each other. One cylinder 20 has its two ends rotatably connected to one side edge of the processing platform 21 and one side edge of the processing plate 22, respectively, while the other cylinder 20 has its two ends rotatably connected to the other side edge of the processing platform 21 and the other side edge of the processing plate 22, respectively. Controlling the extension and retraction of the two cylinders 20 can respectively raise the first suction pipe 291 or the feed pipe 282. By raising the first suction pipe 291 and the feed pipe 282 respectively, the resin mixture can fully impregnate the core material board 11 and the reinforcing material.

[0071] Specifically, the processing plate 22 is cyclically lifted on both sides according to a preset cycle, thereby allowing the resin mixture to fully impregnate the core material plate 11 and the reinforcing material. The preset cycle can be 5 minutes, which can be set according to specific circumstances.

[0072] 306. The enclosed space is cured to obtain the initial fiberglass component.

[0073] In this embodiment of the invention, the temperature of the enclosed 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.

[0074] 307. Remove the initial fiberglass component and perform post-processing to obtain the target fiberglass component.

[0075] Specifically, the flexible membrane layer 27 is removed, the initial fiberglass component is taken out and cut to the preset size to obtain the target fiberglass component.

[0076] like Figure 1 As shown, the target fiberglass component is fiberglass component 10. The target fiberglass component includes a core material board 11 and a reinforcing layer 112 enclosing the core material board 11. The reinforcing layer 112 includes reinforcing material and a resin mixture cured within the reinforcing material. The reinforcing layer 112 fills through-holes 111. With the reinforcing material as a framework and the resin mixture as a filler, the reinforcing layer 112 has higher strength.

[0077] This invention utilizes a composite structure design of a core material, upper and lower 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 upper and lower reinforcing materials through the through-holes, effectively enhancing the overall integrity of the component and avoiding the problem of interlayer delamination in traditional multi-layer components.

[0078] By adjusting the angle between the steel plate and the core material and the horizontal direction, and combining it with the vacuum infusion process, the resin is ensured to fully wet all reinforcing materials, the core material, and the surface of the steel plate. This results in a uniform and dense internal structure of the component, further improving the component's strength and structural stability.

[0079] Compared to related technologies, the preparation method of fiberglass components includes: preparing a core material board, wherein the core material board has multiple spaced through holes; laying reinforcing material in the through holes of the core material board; laying reinforcing material on the surface of the core material board to cover the core material board, and placing the covered core material board on a processing board; covering the core material board with a flexible film layer, the flexible film layer and the processing board forming a sealed space; evacuating the sealed space, injecting a resin mixture into the sealed space so that the resin mixture immerses the core material board and the reinforcing material, the resin mixture including resin; curing the sealed space to obtain an initial fiberglass component; removing the initial fiberglass component and performing post-processing to obtain a target fiberglass component, wherein the target fiberglass component includes a core material board and a reinforcing layer covering the core material board, the reinforcing layer including reinforcing material and a resin mixture cured inside the reinforcing material, and the reinforcing layer filling the through holes. This invention enables fiberglass components to improve structural strength under weight-limited conditions.
