[0002] Fiber-reinforced plastic (FRP) is a high-performance structural material formed by mixing fibers and a resin matrix in a specific ratio and undergoing a specific molding process. It offers advantages such as lightness, high strength, corrosion resistance, and design flexibility. FRP can be manufactured into a variety of products, including fiber cloth, reinforcement, mesh, pultruded profiles, and hand-layup products.

They can be used as reinforcements in concrete structures to resist chemical corrosion, and can also be directly used as load-bearing structures, such as FRP truss bridges and FRP bridge decks. However, the current pultrusion process can only produce straight or arc-shaped profiles, and the production of FRP products with different cross-sectional forms requires the manufacture of different molds, which are relatively expensive.

[0040] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0041] The new FRP profile of the embodiment of the present invention includes a first connecting component 4, a flange 1 and a web 2. Flanges 1 are provided at both ends of the web 2 in the height direction. The web 2 includes a first plate 211 extending in the extension direction of the web 2 and a second plate 221 extending in the height direction of the web 2. There are multiple first plates 211, and the multiple first plates 211 are connected in sequence in the height direction of the web 2. There are multiple second plates 221, and the multiple second plates 221 are connected in sequence in the extension direction of the web 2. The first connecting component 4 is arranged between the first plate 211 and the second plate 221. One end of the first connecting component 4 is connected to the first plate 211, and the other end of the first connecting component 4 is connected to the second plate 221.

[0042] Specifically, if Figures 1 to 2 As shown, the web 2 extends in the up-down direction, the height direction of the web 2 is the up-down direction, and the extension direction of the web 2 is the front-back direction.

[0043] The first plate 211 extends in the front-to-back direction, and a plurality of first plates 211 are arranged in the up-down direction, and the plurality of first plates 211 are sequentially connected in the up-down direction, that is, the plurality of first plates 211 are arranged in the up-down direction.

[0044] The second plate 221 extends in the up-down direction, and the plurality of second plates 221 are arranged in the front-to-back direction, and the plurality of second plates 221 are sequentially connected in the front-to-back direction. A first connecting component 4 is provided between the first plate 211 and the second plate 221, and one end of the first connecting component 4 is connected to the first plate 211, and the other end of the first connecting component 4 is connected to the second plate 221, thereby connecting the first plate 211 and the second plate 221 through the first connecting component 4 to form a web 2.

[0045] Furthermore, the number of the first plate 211 and the second plate 221 may be one. In this case, the first plate extends in the front-to-back direction, and the second plate extends in the up-down direction.

[0046] The flange 1 extends in the front-to-back direction, and flanges 1 are provided at both ends of the web 2 in the upper and lower directions, that is, the upper end of the web 2 is connected to one flange 1, and the lower end of the web 2 is connected to another flange 1, or it can be understood that the upper end of at least one first plate 211 among the multiple first plates 211 is connected to a flange 1, and another first plate 211 is below the first plate 211, and the lower end of another first plate 211 is connected to another flange 1.

[0047] The first plate 211 can be a curved plate. For example, the curvature of the web 2, i.e., the curvature of the web 2, is determined to set the curvature of the first plate 211 and the second plate 221, thereby setting the curvature of the first plate 211 and the second plate 221. The curvature or curvature of the first plate 211 in the vertical direction is coordinated with each other, while the curvature or curvature of the second plate 221 in the front-to-back direction is coordinated with each other, thereby forming a web 2 with a predetermined curvature. The flange 1 is connected to the web 2. It is understood that the flange 1 has a certain degree of elasticity to facilitate bending to adapt to the web 2, and the flange 1 is bent and connected to the web 2 to form a profile with a predetermined curvature.

[0048] Furthermore, the web 2 is arranged orthogonally to the flange 1. For example, the height direction of the web 2 is orthogonal to the width direction of the flange 1. The width direction of the flange 1 is the left-right direction, thereby forming an I-shaped profile, thereby improving the load-bearing capacity and bending stiffness of the profile.

[0049] The web 2 and flange 1 are arranged orthogonally, resulting in two parallel flanges 1 at the upper and lower ends of the profile. This structure allows the profile to maintain high stability when subjected to compression or tension. When subjected to external forces, it can more evenly distribute stress, thereby improving its overall structural strength.

[0050] The novel FRP profile of the embodiment of the present invention sets the curvature of the first plate 211 and the second plate 221 by determining the curvature of the web 2, that is, the curvature of the web 2, and then sets the curvature of the first plate 211 and the second plate 221. A plurality of first plates 211 are spliced. For example, the curvature or curvature of the first plates 211 in the up and down directions are matched with each other for splicing. At the same time, the curvature or curvature of the second plates 221 in the front and back directions are matched with each other and connected. The spliced ​​first plates 211 and the second plates 221 are connected and fixed by the first connecting component 4, and then the web 2 of the profile is manufactured to form a web 2 with a preset curvature. The first plate 211 and the second plate 221 can use waste plates cut out of the factory, which reduces resource waste and reduces manufacturing costs.

[0051] In some embodiments, a plurality of first plates 211 are connected to form a horizontal support plate 21, and a plurality of second plates 221 are connected to form a height support plate 22.

[0052] There are multiple first plates 211 and multiple second plates 221. Multiple first plates 211 are sequentially connected in the height direction of the web 2 to form a horizontal support plate 21. Multiple second plates 221 are connected in the extension direction of the web 2 to form a height support plate 22.

[0053] The horizontal support plates 21 and the height support plates 22 are arranged in sequence in the width direction of the web 2 , or the horizontal support plate is provided between at least two height support plates 22 .

[0054] Specifically, if Figures 1 to 2 As shown, multiple first plates 211 are connected to form a horizontal support plate 21. For example, the first plates 211 in the up and down directions are correspondingly connected to form a horizontal support plate 21, thereby improving the structural strength of the web 2 in the left and right directions.

[0055] A plurality of second plates 221 are connected to form a height support plate 22 . The second plates 221 extend in the vertical direction to improve the shear performance of the profile in the height direction, so that the profile can maintain high stability when subjected to bending loads in the vertical direction.

[0056] The horizontal support plates 21 and the height support plates 22 are arranged in sequence in the width direction of the web 2, that is, the horizontal support plates 21 and the height support plates 22 are arranged alternately in the left and right directions, and a first connecting component 4 is provided between the horizontal support plates 21 and the height support plates 22 to connect the horizontal support plates 21 and the height support plates 22 to form the web 2, thereby improving the bearing capacity and the integrity of the web 2 in the left and right directions.

[0057] The horizontal support plate is arranged between at least two height support plates 22. It can be understood that the number of horizontal support plates 21 can be at least one, and the number of height support plates 22 can be at least two. One horizontal support plate is arranged between two height support plates 22, thereby ensuring the integrity of the profile while improving the shear bearing capacity in the up and down directions, reducing the number of horizontal support plates 21, and reducing costs. According to different usage requirements of the profile, different arrangements of horizontal support plates 21 and height support plates 22 can be adopted to achieve a balance between cost and usage requirements.

[0058] In some embodiments, the material of the first plate 211 is at least one of carbon fiber reinforced composite material (CFRP), glass fiber reinforced composite material (GFRP), and basalt fiber reinforced composite material (BFRP), and the second plate 221 is at least one of carbon fiber reinforced composite material (CFRP), glass fiber reinforced composite material (GFRP), and basalt fiber reinforced composite material (BFRP).

[0059] Specifically, if Figures 1 to 2As shown, carbon fiber reinforced composite materials (CFRP) have certain structural strength, fatigue resistance and corrosion resistance, but the cost is high and the brittleness is large.

[0060] Glass fiber reinforced composites (GFRP) have certain structural strength and are easy to process, but have poor wear resistance.

[0061] Basalt fiber reinforced composites (BFRP) have high strength, durability and corrosion resistance, but the extraction and processing of basalt fiber require specific processes and equipment, which is relatively expensive.

[0062] Setting the material of the first plate 211 and the second plate 221 to at least one of carbon fiber reinforced composite material (CFRP), glass fiber reinforced composite material (GFRP), and basalt fiber reinforced composite material (BFRP) allows designers to use different types of first plates 211 and second plates 221 according to actual needs, and then produce different types of webs 2, thereby improving the applicability of the profile.

[0063] In some embodiments, the new FRP profile also includes a second connecting component and a supporting triangle bar 3. The supporting triangle bar 3 is arranged at the connection between the flange 1 and the web 2, and the outer peripheral surface of the supporting triangle bar 3, the connection between the flange 1 and the web 2, and both sides of the web 2 are covered with a second connecting component 5.

[0064] Specifically, if Figures 1 to 2 As shown, the supporting triangle bars 3 are arranged on the left and right sides of the connection between the flange 1 and the web 2 to reduce stress concentration at the connection and improve the integrity of the flange 1 and the web 2.

[0065] In some embodiments, the dimension of the flange 1 in the height direction of the web 2 is 0.5 mm to 20 mm, and the first connecting member 4 and the second connecting member 5 are fiber cloth.

[0066] Specifically, if Figures 1 to 2 As shown, the size of the flange 1 in the up and down directions is 0.5mm-20.0mm, which can not only enable the flange 1 to maintain a certain structural strength, but also when the web 2 is a web 2 with a certain curvature, the flange 1 can cooperate with the web 2 to bend so that the web 2 and the flange 1 are connected to facilitate the production of the profile, thereby enhancing the structural strength and stability of the profile.

[0067] When the load-bearing capacity of the profile in the vertical direction is small, a 0.5 mm flange 1 can be used to reduce costs. When the load-bearing capacity of the profile in the vertical direction is large, a 20.0 mm flange 1 can be used to increase the structural strength of the profile.

[0068] The novel FRP profile gluing preparation method according to the embodiment of the present invention includes:

[0069] Determine the curvature of the profile, determine the curvature of the web 2 according to the curvature of the profile, determine the shape of the horizontal support plate 21 and the shape of the height support plate 22 according to the curvature of the web 2, and determine the preset curvatures of the first plate 211 and the second plate 221;

[0070] Process the surfaces of the first plate 211, the second plate 221 and the supporting triangle bar 3, connect the prepared first plate 211 and the second plate 221 with fiber cloth, fix the web 2 and then solidify;

[0071] The web 2 and the flange 1 are fixed, and a fiber cloth is provided between the web 2 and the flange 1;

[0072] Support triangle bars 3 are provided on both sides of the connection between the web 2 and the flange 1, and fiber cloth is used to cover both sides of the web 2, the connection between the flange 1 and the web 2, and the outer periphery of the support triangle bars 3;

[0073] Solidify the entire profile.

[0074] Specifically, if Figures 1 to 2 As shown, the shape of the profile is determined, and the curvature of the web 2 is determined based on the shape of the profile. That is, the curvature of the web 2 is determined by the curvature or degree of curvature of the profile. The curvature of the first plate 211 and the second plate 221 is determined by the curvature of the web 2, that is, the curvature of the first plate 211 and the second plate 221, and then the curvature of the first plate 211 and the second plate 221 is set. At the same time, the curvature or curvature of the first plate 211 in the vertical direction is coordinated with each other, and the curvature or curvature of the second plate 221 in the front-to-back direction is coordinated with each other, thereby forming a web 2 with a preset curvature. The flange 1 is connected to the web 2. It is understood that the flange 1 has a certain degree of elasticity and is easy to bend to adapt to the web 2. Then, the flange 1 is bent and connected to the web 2 to form a profile with a preset curvature.

[0075] The first plate 211 and the second plate 221 are subjected to surface treatment. The surfaces of the first plate 211 and the second plate 221 are roughened. The surfaces of the supporting triangle bar 3 are also roughened to facilitate connecting the first plate 211 and the second plate 221 with the fiber cloth and to facilitate covering the supporting triangle bar 3 with the fiber cloth.

[0076] After the fabricated first plate 211 and second plate 221 are connected with fiber cloth, multiple first plates 211 are connected to form the horizontal support plate 21, and multiple second plates 221 are connected to form the height support plate 22. The web 2 is temporarily fixed with a wooden mold and cured by vacuum-introducing resin to form the web 2. The upper and lower ends of the glued web 2 are polished to remove the trapezoidal corners.

[0077] Then, supporting triangle bars 3 are set on both sides of the connection between the web 2 and the flange 1, and fiber cloth is used to cover the two sides of the web 2, the connection between the flange 1 and the web 2, and the outer periphery of the supporting triangle bar 3. The flange 1 and the web 2 are temporarily fixed by a wooden mold, and then vacuum-introduced resin is used to solidify them into a whole.

[0078] The novel FRP profile gluing preparation method of the embodiment of the present invention determines the shape of the profile, determines the curvature of the web 2 according to the shape of the profile, determines the shape of the horizontal support plate 21 and the shape of the height support plate 22 according to the curvature of the web 2, and then splices the first plate 211 to form the horizontal support plate 21, and splices the second plate 221 to form the height support plate 22. The first plate 211 and the second plate 221 are connected by fiber cloth to form a web 2 with a preset curvature. There is no need to set up a special mold for the one-piece molding of the web 2, thereby saving the mold opening cost and reducing the manufacturing difficulty. At the same time, waste plates cut by the factory can be used to reduce resource waste and reduce manufacturing costs.

[0079] In some embodiments, after determining the curvature of the web 2, a first plate 211 and a second plate 221 with a preset curvature are manufactured by a subtractive process.

[0080] After the web 2 is fixed, the fiber cloth is fully impregnated with resin by vacuum introduction, and the resin is cured to form the web 2. Compared with the new FRP profile produced by pultrusion, the present application uses a first plate 211 and a second plate 221 to form the web 2, eliminating mold making costs and reducing manufacturing difficulty. At the same time, waste plates cut from the factory can be used, reducing resource waste and lowering manufacturing costs.

[0081] In some embodiments, before fabricating the web 2, the surfaces of the first plate 211, second plate 221, and supporting triangle bars 3 are sandblasted or polished. Roughening the surfaces of the first plate 211, second plate 221, and supporting triangle bars 3 increases the interfacial contact area, improves interfacial properties, and enhances the stability of the connection between the fiber cloth and the profile. Alternatively, polishing the surfaces of both the FRP plate and the triangle bars 302 facilitates epoxy resin bonding.

[0082] In some embodiments, the curing resin is any one of epoxy resin, polyurethane, or polyethylene resin. The choice of epoxy resin, polyurethane, or polyethylene resin can be tailored to the needs of the operator and the specific application scenario and requirements. The resin can be selected based on the environment in which the profile is to be used, thereby increasing the stability of the profile.

[0083] In some embodiments, the fiber cloth is made of at least one of glass fiber, carbon fiber, aramid fiber, and basalt fiber. The fiber cloth can have fiber orientations of 0°, 90°, or ±45° to increase the shear strength of the connecting components. A 45° fiber cloth orientation can reduce stress concentration between layers. A 0° fiber orientation primarily enhances the tensile and compressive strength of the material, especially when the load direction aligns with the fiber orientation. A 90° fiber orientation primarily improves the material's resistance to bending and extrusion, making it particularly suitable for applications requiring bidirectional bending or resistance to external extrusion.

[0084] In some embodiments, the first and second panels are cut and manufactured from production waste, and the webs, flanges, and support triangles are fixed during gluing, that is, the webs, flanges, and support triangles are fixed during resin injection or splicing.
