Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile technology, specifically to a triaxially reinforced composite woven structure. Background Technology
[0002] As is well known in the art, composite fabrics are made of fibrous materials that form woven, knitted, and nonwoven materials. They are typically formed using glass fibers, carbon fibers, and graphite fibers, with multiple layers stacked and cut into dry fabric preforms.
[0003] Existing fabrics are woven fabrics of a certain thickness formed by joining yarns from at least two systems together. However, the weaving method is simple and the weaving is relatively heavy, which cannot achieve the specified penetration rate, resulting in low production efficiency and an inability to meet the growing market demand. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a triaxial reinforced composite woven structure. This structure solves the problem that existing fabrics are woven fabrics with a certain thickness formed by interlacing yarns from at least two systems. However, the weaving method is singular and the weaving is relatively heavy, failing to achieve the specified penetration rate, resulting in low production efficiency and an inability to meet the growing market demand.
[0005] The technical solution adopted by this utility model is: a triaxial reinforced composite woven structure, including a first axial fabric, a second axial fabric and a diagonal fabric; the first axial fabric and the second axial fabric are woven in a cross direction, and an interlacing reinforcement portion is formed at the interlacing point of the first axial fabric and the second axial fabric; the diagonal fabric is interlaced in a cross shape on the interlacing reinforcement portion and connected to the first axial fabric and the second axial fabric.
[0006] A further improvement to the above scheme is that the first axial fabric is carbon fiber, the second axial fabric is aramid with restraint, and the oblique fabric is nickel-titanium alloy wire.
[0007] A further improvement to the above scheme is that the interlacing direction of the oblique fabric intersects the directions of the first axial fabric and the second axial fabric at a 45° angle.
[0008] A further improvement to the above scheme is that the weaving gap between the first axial fabric and the second axial fabric is 3-5 mm.
[0009] A further improvement to the above scheme is that the interlacing density of the first axial fabric and the second axial fabric is 50-80in.
[0010] A further improvement to the above scheme is that the oblique fabric is interwoven on the composite fabric to form a mesh structure.
[0011] A further improvement to the above scheme is that the nickel-titanium alloy wire is 0.08 mm thick.
[0012] A further improvement to the above scheme is that the specific strength of the nickel-titanium alloy wire is 2000 N / mm².
[0013] The beneficial effects of this utility model are:
[0014] Compared to existing composite weaving, this invention forms a stable basic structure by tightly weaving the first axial fabric and the second axial fabric in a cross direction. At the intersection of the two fabrics, there is a specially designed interlacing reinforcement section, which enhances the overall strength and stability of the structure. By adding the diagonal fabric, it is cleverly interlaced in a cross shape on the interlacing reinforcement section, which not only further improves the strength of the structure, but also achieves a tight connection with the first axial fabric and the second axial fabric, ensuring the coordination and durability of the entire structure. The structure is compact and highly practical. Attached Figure Description

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0023] like Figure 1-2 As shown in the embodiment of this utility model, a triaxially reinforced composite woven structure includes a first axial fabric 10, a second axial fabric 20, and a bias fabric 30. The first axial fabric 10 and the second axial fabric 20 are woven in a cross direction, and an interlacing reinforcement portion is formed at the interlacing point of the first axial fabric 10 and the second axial fabric 20. The bias fabric 30 is interlaced in a cross shape on the interlacing reinforcement portion and is connected to the first axial fabric 10 and the second axial fabric 20. In this embodiment, the first axial fabric 10 and the second axial fabric 20 are tightly woven in a cross direction, forming a stable basic structure. At the interlacing point of the two, an interlacing reinforcement portion is specially designed to enhance the overall strength and stability of the structure. The addition of the bias fabric 30, which is cleverly interlaced in a cross shape on the interlacing reinforcement portion, not only further improves the strength of the structure but also achieves a tight connection with the first axial fabric 10 and the second axial fabric 20, ensuring the coordination and durability of the entire structure. The structure is compact and highly practical.
[0024] like Figure 1 As shown, the first axial fabric 10 is carbon fiber, the second axial fabric 20 is aramid for restraint, and the oblique fabric 30 is nickel-titanium alloy wire. In this embodiment, by using carbon fiber as the first axial fabric 10, the strength and stiffness of the composite material can be significantly improved, meeting the high strength requirements. The second axial fabric 20 uses aramid for restraint, and aramid, with its excellent wear resistance and tear resistance, effectively enhances the durability and stability of the material. The oblique fabric 30 uses nickel-titanium alloy wire, which utilizes its excellent elasticity and shape memory characteristics, allowing the entire composite woven structure to adapt to deformation more flexibly under stress, maintaining the integrity and stability of the structure. This triaxial reinforced composite woven structure integrates the advantages of different materials, achieving a perfect combination of high strength, high wear resistance, and good elasticity, greatly improving the overall performance of the composite material.
[0025] like Figure 2As shown, the interlacing direction of the oblique fabric 30 intersects the directions of the first axial fabric 10 and the second axial fabric 20 at a 45° angle. In this embodiment, the 45° intersection angle formed by the first axial fabric 10 and the second axial fabric 20 greatly enhances the overall performance of the triaxial reinforced composite woven structure. Through the 45° intersection, the oblique fabric 30 can not only effectively disperse stress from different directions and improve the tear resistance and tensile strength of the material, but also make the entire structure exhibit balanced mechanical properties in multiple dimensions.
[0026] The weaving gap between the first axial fabric 10 and the second axial fabric 20 is 3-5 mm. In this embodiment, the carefully designed weaving gap between the first axial fabric 10 and the second axial fabric 20 ensures that the composite woven structure maintains high strength while also possessing good flexibility and breathability; it effectively avoids excessive tightness inside the structure, reduces friction and wear of the material during use, and thus extends the service life of the composite fabric.
[0027] The interlacing density of the first axial fabric 10 and the second axial fabric 20 is 50-80in. In this embodiment, by designing the interlacing density of the first axial fabric 10 and the second axial fabric 20 to be 50-80in, it is ensured that the fabric maintains sufficient strength while also possessing good flexibility and tear resistance; this allows the fabric to more effectively disperse stress when subjected to external forces, thereby improving overall durability and reliability.
[0028] The bias fabric 30 forms a mesh structure on the composite fabric through interlacing. In this embodiment, the bias fabric 30 is cleverly integrated into the composite fabric through interlacing, which enhances the overall stability of the composite fabric and significantly improves its tensile and tear resistance. The formation of the mesh structure enables the composite fabric to exhibit excellent mechanical properties in multiple directions, effectively resisting various external stresses.
[0029] The nickel-titanium alloy wire has a diameter of 0.08 mm. In this embodiment, the nickel-titanium alloy wire, with its precise diameter of 0.08 mm, greatly enhances the overall strength and stability of the material. Furthermore, the excellent elasticity and shape memory properties of the nickel-titanium alloy wire play a crucial reinforcing role in the structure, enabling the composite material to withstand significant forces and deformations in multiple directions.
[0030] The specific strength of the nickel-titanium alloy wire is 2000 N / mm². In this embodiment, the high specific strength of the nickel-titanium alloy wire provides the composite structure with excellent load-bearing capacity and resistance to deformation, enabling the structure to perform well under complex stresses and improving the overall performance of the material.
[0031] A triaxially reinforced composite woven structure includes a first axial fabric 10, a second axial fabric 20, and a bias fabric 30. The first axial fabric 10 and the second axial fabric 20 are woven in a cross direction, and interlacing reinforcement portions are formed at the interlacing points of the first axial fabric 10 and the second axial fabric 20. The bias fabric 30 is interlaced in a cross shape on the interlacing reinforcement portions and is connected to the first axial fabric 10 and the second axial fabric 20. In this embodiment, the first axial fabric 10 and the second axial fabric 20 are tightly woven in a cross direction, forming a stable basic structure. At the interlacing points of the two, interlacing reinforcement portions are specially designed to enhance the overall strength and stability of the structure. The addition of the bias fabric 30, which is cleverly interlaced in a cross shape on the interlacing reinforcement portions, not only further improves the strength of the structure but also achieves a tight connection with the first axial fabric 10 and the second axial fabric 20, ensuring the coordination and durability of the entire structure. The structure is compact and highly practical.
[0032] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
