Abstract
Description
Technical Field
[0001] This invention relates to the field of pultrusion technology, and in particular to a pultruded material, production method and product of a carbon fiber and glass fiber composite. Background Technology
[0002] Currently, the reinforcing materials used in pultrusion processes are mainly carbon fiber and glass fiber. Most pultrusion methods use a single reinforcing material to produce products, only leveraging the inherent advantages of the material itself. Furthermore, there is a significant difference in performance and cost between the two materials. Pure carbon fiber pultruded materials or products exhibit excellent mechanical properties, particularly in modulus and fatigue resistance; their tensile modulus and fatigue M-value are more than twice that of ordinary glass fiber. However, carbon fiber is expensive, costing more than ten times that of ordinary glass fiber, resulting in relatively high prices for pultruded products. Conversely, improving or enhancing tensile and fatigue resistance is extremely difficult compared to ordinary pure glass fiber pultruded materials or products. This creates two extremes in performance and price, limiting the design and selection of products, especially in wind turbine blade design, selection, and application. Summary of the Invention

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, 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. It should be noted that, unless otherwise specified, the embodiments and feature vectors in the embodiments of this application can be arbitrarily combined with each other.
[0024] Currently, the reinforcing materials used in pultrusion processes are mainly carbon fiber and glass fiber. Most pultrusion methods use a single reinforcing material to produce products, only leveraging the inherent advantages of the material itself. Furthermore, there is a significant difference in performance and cost between the two materials. Pure carbon fiber pultruded materials or products exhibit excellent mechanical properties, particularly in modulus and fatigue resistance. Their tensile modulus and fatigue M-value are more than twice that of ordinary glass fiber (the tensile modulus of carbon fiber pultruded materials is above 150 GPa, with an M-value of around 20; ordinary glass fiber pultruded materials, taking E7 as an example, have a tensile modulus of around 60 GPa and an M-value of 8-10). However, carbon fiber is expensive, costing more than ten times that of ordinary glass fiber, resulting in relatively high prices for pultruded products. Conversely, improving and enhancing tensile and fatigue resistance is extremely difficult compared to ordinary pure glass fiber pultruded materials or products. This creates two extremes in performance and price, limiting the design and selection of products, especially in wind turbine blade design, selection, and application.
[0025] This application provides a carbon fiber and glass fiber hybrid pultruded material, which is formed by pultruding carbon fiber and glass fiber together. By improving the pultrusion method, the compatibility between glass fiber and carbon fiber is improved, while the performance of carbon fiber is better utilized.
[0026] The carbon fiber and glass fiber blended pultruded material of this application includes carbon fiber, glass fiber and resin, wherein the total content of carbon fiber and glass fiber is 50% to 75% by volume percentage, and the content of carbon fiber is more than 10% of the total content of carbon fiber and glass fiber.
[0027] As an example, carbon fibers are aggregated in a predetermined area or uniformly distributed within glass fibers.
[0028] As an example, carbon fibers form a carbon fiber framework, and glass fibers are wrapped within the carbon fiber framework.
[0029] As an example, the resin is an epoxy resin or a vinyl resin.
[0030] Based on the above example, one feasible implementation involves further adding a release agent, appropriate fillers, etc., to the resin.
[0031] The carbon fiber and glass fiber mixed pultruded material of this application is produced by the production method of this application.
[0032] The method for producing carbon fiber and glass fiber hybrid pultruded materials of this application is carried out in a pultrusion system for carbon fiber and glass fiber pultruded materials, such as... Figure 2 As shown, the pultrusion system includes a yarn frame 01, an impregnation tank 03, an asphalt grid 04, a first preform plate 05, and a pultrusion die 06.
[0033] like Figure 1 As shown, the production method of this application includes the following steps:
[0034] S1 pulls carbon fibers and glass fibers arranged according to a predetermined rule into the impregnation tank 03, impregnating the carbon fibers and glass fibers in the resin of the impregnation tank 03.
[0035] S2 pulls carbon fiber and glass fiber through the grid of asphalt grid 04 to remove excess resin from the surface of carbon fiber and glass fiber.
[0036] S3 pulls carbon fiber and glass fiber through the first preforming plate 05. The first preforming plate 05 has a first preforming hole with a predetermined shape. The first preforming hole extrudes the carbon fiber and glass fiber into a carbon fiber-glass fiber structure with a first predetermined shape.
[0037] S4 pulls the carbon fiber-glass fiber structure of the first predetermined shape into the pultrusion die 06. The carbon fiber-glass fiber structure of the first predetermined shape is cured and shaped by passing through the first heating zone, the second heating zone and the third heating zone of the pultrusion die 06, where the temperature increases sequentially. The pultruded material of carbon fiber and glass fiber is then pulled out from the pultrusion die 06.
[0038] The traction speed for traction carbon fiber and glass fiber is 0.2-2 m / min.
[0039] As an example, the impregnation tank 03 is a constant temperature closed circulation impregnation tank, and the resin temperature in the impregnation tank 03 is maintained at 30℃~40℃.
[0040] As an example, the temperatures of the first, second, and third heating zones gradually increase within the range of 130℃ to 190℃. For instance, the first heating zone is 130℃ to 140℃, the second heating zone is 150℃ to 170℃, and the third heating zone is 170℃ to 190℃.
[0041] As an example, such as Figure 1 As shown, the production system also includes an intermediate perforated plate 02 disposed between the yarn frame 01 and the impregnation tank 03, the intermediate perforated plate 02 including multiple through holes; the first end wall of the impregnation tank 03 includes a first yarn threading plate 031, the first yarn threading plate 031 including multiple first holes; the second end wall includes a second yarn threading plate 032, the second yarn threading plate 032 of the impregnation tank 03 including multiple second holes.
[0042] Step S1 includes the following steps:
[0043] S11 arranges carbon fibers and glass fibers on the yarn frame 01 according to a predetermined rule, with the carbon fibers clustered in a predetermined area or evenly distributed among the glass fibers.
[0044] S12 traction carbon fiber and glass fiber pass through the through holes of the intermediate perforated plate 02 according to a predetermined rule, with a predetermined number of carbon fibers and / or glass fibers passing through each through hole.
[0045] S13 traction carbon fiber and glass fiber pass through the first hole of the first threading plate 031 of the impregnation tank 03 according to a predetermined rule.
[0046] S14 pulls carbon fiber and glass fiber through the impregnation tank 03 according to a predetermined rule, and then pulls carbon fiber and glass fiber through the second hole of the second threading plate 032 of the impregnation tank 03 to exit the impregnation tank 03.
[0047] The yarn path of carbon fiber passing through the intermediate perforated plate 02 and then through the first yarn-threading plate 031 of the impregnation tank 03 is a straight line; the yarn path of glass fiber passing through the intermediate perforated plate 02 and then through the first yarn-threading plate 031 of the impregnation tank 03 into the impregnation tank 03 is also a straight line.
[0048] As an example, the first hole includes a plurality of first threading holes 0311, a plurality of second threading holes 0312 and a plurality of third threading holes 0313.
[0049] Step S14 includes the following steps: Step S141, a portion of the glass fibers are divided into M groups, each group including m glass fibers. The M groups of glass fibers pass through the first threading hole 0311 and enter the impregnation tank 03, and the m glass fibers are impregnated together to form a first glass fiber bundle; another portion of the glass fibers are divided into N groups, each group including n glass fibers. The N groups of glass fibers pass through the second threading hole 0312 and enter the impregnation tank 03, and the n glass fibers are impregnated together to form a second glass fiber bundle; the traction carbon fiber passes through the third threading hole 0313, and each third threading hole 0313 passes through one or more carbon fibers; wherein, m≥1, n≥1.
[0050] As an example, the asphalt path of carbon fiber and glass fiber through the grid of asphalt grating 04 is wavy and undulating. Under these conditions, while extruding excess resin from the surfaces of carbon fiber and glass fiber, the tension of the carbon fiber and glass fiber is maintained. In this step, the asphalt path of the glass fiber maintains the straightness of the glass fiber. High straightness of the glass fiber reduces pultrusion resistance, maximizes the maintenance of the tensile modulus and fatigue resistance of the glass fiber, reduces the performance gap between glass fiber and carbon fiber, and better leverages the excellent performance of carbon fiber in composite pultrusion materials.
[0051] As an example, along the pultrusion direction, the asphalt grid 04 includes several grids 041 perpendicular to the pultrusion direction of the composite material; the grid includes multiple horizontally arranged parallel grid bars, with adjacent grid bars forming a grid, and the number of rows of the grid is the same as the number of rows of the first holes on the first threading plate 031; after the carbon fibers and glass fibers pass through the impregnation tank 03, they are arrayed and layered through the grid to remove excess resin from the fiber surface; wherein, the adjacent grids are set at different heights, and the trajectory of the carbon fibers and glass fibers passing through the grid of the several grids 041 is wavy and convex.
[0052] As an example, the following steps are included after step S3 and before step S4:
[0053] In step S5, a carbon fiber-glass fiber structure of a first predetermined shape is drawn through a second preforming plate, which has a second preforming hole of a predetermined shape. The shape of the second preforming hole is reduced relative to the first preforming hole by a predetermined ratio. The carbon fiber-glass fiber structure of the first predetermined shape is extruded through the second preforming plate into a carbon fiber-glass fiber structure of the second predetermined shape. In step S4, the carbon fiber-glass fiber structure of the second predetermined shape is drawn into the pultrusion die 06.
[0054] As an example, the size of the second preformed hole is 0.6 to 0.8 times that of the first preformed hole, which reduces the operational difficulty of the subsequent pultrusion process.
[0055] As an example, step S4 is followed by a post-curing step S6:
[0056] Step S6 involves feeding the carbon fiber and glass fiber pultruded material into the post-curing zone 07, where it is heated at a predetermined temperature to further cure it. Under these conditions, post-curing can further eliminate internal stress in the composite pultruded material and improve the bond strength between the carbon fiber and glass fiber in the composite pultruded material.
[0057] As an example, along the direction of the composite material pultrusion production line, the post-curing zone 07 includes at least one oven 070 arranged sequentially, with an oven temperature of 130°C to 190°C. For example, along the production line direction, the post-curing zone includes a first oven, a second oven, and a third oven arranged sequentially, with the first oven having a temperature of 130°C to 140°C, the second oven having a temperature of 150°C to 170°C, and the third oven having a temperature of 170°C to 190°C.
[0058] As a specific embodiment of this example, such as Figure 2 As shown, the first threading plate 031 of the impregnation tank 03 is an array perforated plate, and the second threading plate 032 is the same array perforated plate as the first threading plate 031.
[0059] The first threading plate 031 includes the first hole in row P and column Q; the first hole in the first row and the second row is the third threading hole 0313; the first hole in row P and row P-1 is the third threading hole 0313. The third row to row P-2 are the first threading hole rows and the second threading hole rows arranged alternately.
[0060] Based on the above example, in one feasible implementation, two glass fibers are bonded together as a group by passing through the first threading hole 0311 and impregnating with resin in the impregnation tank 03. Each second threading hole 0312 passes through one glass fiber into the impregnation tank 03 for resin impregnation. Each third threading hole 0313 passes through one carbon fiber into the impregnation tank 03 for resin impregnation.
[0061] Under these conditions, the resulting composite fiber pultruded material is as follows: Figure 4 As shown, it includes a carbon fiber shell 100 and a glass fiber core 200 encased in the carbon fiber shell 100; the glass fiber core 200 includes a first glass fiber layer 210 and a second glass fiber layer 220 laid at intervals, the first glass fiber layer 210 being formed by bonding first glass fiber bundles; the second glass fiber layer 220 being formed by bonding single glass fibers.
[0062] Based on the above example, in a preferred embodiment, the first hole in the first column of the second row and the first hole in the Nth column of the first threading plate 031 is the second threading hole 0312; the first hole in the first column of the (M-1)th row and the first hole in the Nth column are the second threading holes 0312.
[0063] As another embodiment of this application, such as Figure 5 As shown, the first threading plate 031 of this application includes a first threading hole 0311 for passing glass fiber and a third threading hole 0313 for passing carbon fiber. The first threading plate 031 is a threading hole plate with P rows and Q columns, where P≥3 and Q≥2; at least one row of first holes between the first row and the P-th row of the first threading plate 031 are all third threading holes 0313 for passing carbon fiber.
[0064] Under these conditions, the pultruded material obtained by pultrusion is as follows: Figure 6 As shown, it includes a glass fiber layer 400 and a carbon fiber layer 500 formed between the glass fiber layers 400 to enhance the pultrusion modulus and fatigue resistance of the pultruded material.
[0065] Based on the above example, in a preferred embodiment, the first row of the first threading plate 031 is provided with a plurality of third threading holes 0313 at intervals, and the threading holes in the first row are first threading holes 0311; the Mth row is provided with a plurality of third threading plates 0313 at intervals, and the other threading holes in the Mth row are first threading holes 0311. Under this condition, as Figure 7 As shown, multiple carbon fibers 600 are uniformly distributed on the side of the glass fiber layer 400 of the pultruded material away from the carbon fibers.
