Description

Technical Field

[0001] This invention belongs to the field of weaving technology, specifically, it relates to a limiting belt and its three-dimensional weaving technology and application. Background Technology

[0002] Textile composite materials are advanced composite materials that achieve reinforcement using textile fibers and their structural components. Three-dimensional braided composite materials are an important branch of textile structural composite materials. They refer to the use of three-dimensional braiding technology to first weave reinforcing fibers into a three-dimensional integral fabric, and then combine it with a matrix (including resin, carbon, silicon carbide, metal, etc.) to produce three-dimensional braided composite material parts.

[0003] The most distinctive feature of three-dimensional woven fabrics is that they do not have the concept of layers. Three-dimensional woven fabrics are molded in one piece, so three-dimensional woven composite materials are a completely integral structure. They have high specific strength and specific modulus and excellent mechanical properties. Therefore, it is possible to use three-dimensional woven composite materials to make main load-bearing structural components and reinforcements for load-bearing structural components.

[0004] Currently, the aerospace, aviation, and medical fields urgently need various high-performance and functional three-dimensional braided composite material irregular shapes. Therefore, further research on the three-dimensional braiding technology of irregular shapes and three-dimensional braided composite materials is of great significance to the development of the new materials field.

[0005] In view of this, the present invention is hereby proposed. Summary of the Invention

[0006] The purpose of this invention is to overcome the problems of poor mechanical properties, low strength, and the need for post-cutting and sewing of existing three-dimensional braided composite materials. It provides a restraining belt and its three-dimensional braiding process and application, which makes the restraining belt have excellent mechanical properties, simple process, no need for post-cutting and sewing, and improves the overall performance of the restraining belt.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: A three-dimensional braided limiting belt process, the limiting belt includes a strip-shaped body and first and second fixing rings located at both ends of the strip-shaped body, and is braided in the order of first fixing ring - strip-shaped body - second fixing ring.

[0008] The restraining band woven using the weaving process of this invention is a monolithic structure, avoiding cutting and sewing processes, and has good integrity. The restraining band of this invention is woven from a single yarn along its length and with two closed fixing rings, resulting in good dimensional stability and no weak points. Under the same performance conditions, the restraining band prepared using the weaving process of this invention can further reduce its weight. Furthermore, using the weaving process of this invention, components with a similar shape to the restraining band of this invention can be woven and widely used in aviation, aerospace, energy, transportation, sports, and other fields to achieve the purpose of increasing strength and reducing weight.

[0009] Furthermore, weaving the first fixing loop includes: arranging the required yarns into m rows and n columns according to the width and thickness of the first fixing loop, controlling the weaving of a certain length from one side and then folding it in half to form the first fixing loop; and / or, controlling the weaving of the first fixing loop from both sides to form the first fixing loop.

[0010] The weaving process of the first fixing ring is simple, and after the first fixing ring is woven, the weaving of the strip body can continue. There is no need to sew the first fixing ring to the strip body separately, which simplifies the production process.

[0011] Furthermore, the weaving of the strip-shaped body includes: after the first fixing ring is woven, the two ends of the yarn are twisted together and arranged into m rows and 2n columns, or 2m rows and n columns, to form the strip-shaped body.

[0012] Furthermore, the strip-shaped body comprises a first strip-shaped body with a reduced width and an increased thickness, and a second strip-shaped body with an increased width and a reduced thickness. During the weaving process, the number of yarns involved in the weaving remains unchanged. First, the yarn arrangement is adjusted by reducing the number of row yarns and increasing the number of column yarns to form the first strip-shaped main body. Then, the second strip-shaped main body is formed by increasing the number of row yarns and decreasing the number of column yarns.

[0013] The number of yarns involved in the weaving remains basically constant, ensuring that the outer surface of the woven retaining band will not have obvious sharp edges, thus guaranteeing the smoothness of the retaining band surface.

[0014] Furthermore, when weaving the first strip-shaped main body, the yarn arrangement changes from m rows and 2n columns to mk rows and 2n+t columns. When weaving the second strip-shaped main body, the yarn arrangement changes from mk rows and 2n+t columns to m rows and 2n columns. Alternatively, when weaving the first strip-shaped main body, the yarn arrangement changes from 2m rows and n columns to 2m-k rows and n+t columns. When weaving the second strip-shaped main body, the yarn arrangement changes from 2m-k rows and n+t columns to 2m rows and n columns.

[0015] Furthermore, during the process of arrangement changes, If 2*m*n=(mk)*(2n+t), then weave according to this arrangement; If 2*m*n>(mk)*(2n+t), then remove the excess weaving yarn; If 2*m*n < (mk)*(2n+t), then add the corresponding yarn to the corresponding point; or, If 2*m*n = (2m-k)*(n+t), then weave according to this arrangement; If 2*m*n>(2m-k)*(n+t), then remove the excess yarn; If 2*m*n < (2m-k)*(n+t), then add the corresponding yarn to the corresponding point.

[0016] Furthermore, there is a connecting segment between the first and second strip-shaped main bodies, and they are woven in the order of first strip-shaped main body - connecting segment - second strip-shaped main body; Preferably, the weaving of the connecting segment includes: after the first strip body is woven, m*n floating yarns are gradually added, each floating yarn is marked at both ends, and the connecting segment is woven together. After the weaving is completed, m*n yarns are removed from the unmarked yarns.

[0017] Furthermore, after the connecting section is woven, the m*n floating yarns do not participate in the weaving. After the m*n yarns are woven to a certain length, they are folded in half to form the second fixing ring. Preferably, after the second fixing ring is woven, the ends of the m*n floating yarns are connected with the ends of the m*n yarns, and the yarns are pulled through the floating yarns according to the markings on the floating yarns, replacing the corresponding floating yarns with the yarns, thus completing the overall weaving of the limiting belt.

[0018] The present invention provides a three-dimensional woven restraint belt woven using any of the weaving processes described in the above technical solutions.

[0019] The three-dimensional woven restraint belt of this invention has applications in the fields of aviation, aerospace, energy, transportation, and sports.

[0020] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The restraining band woven using the weaving process of this invention is a monolithic structure, avoiding cutting and sewing processes, and has good integrity. The restraining band of this invention is woven from a single yarn along its length and with two closed fixing rings, resulting in good dimensional stability and no weak points. Under the same performance conditions, the restraining band prepared using the weaving process of this invention can further reduce its weight. Furthermore, using the weaving process of this invention, components with a similar shape to the restraining band of this invention can be woven and widely used in aviation, aerospace, energy, transportation, sports, and other fields to achieve the purpose of increasing strength and reducing weight.

[0027] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "contact," and "communication" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Example 1

[0028] like Figures 1 to 3 As shown, this embodiment provides a process for weaving a limiting band. This embodiment is based on a four-step weaving method, and the specific weaving process is as follows: The limiting belt includes a strip-shaped body and a first fixing ring 1 and a second fixing ring 2 located at both ends of the strip-shaped body, which are woven in the order of "first fixing ring 1 - strip-shaped body - second fixing ring 2"; More specifically, the strip-shaped body includes a first strip-shaped body 3 with decreasing width and increasing thickness, a second strip-shaped body 4 with increasing width and decreasing thickness, and a connecting segment 5 located between the first strip-shaped body 3 and the second strip-shaped body 4; the strips are woven in the order of "first fixing ring 1 - first strip-shaped body 3 - connecting segment 5 - second strip-shaped body 4 - second fixing ring 2". The weaving steps include: (1) Design the required number of fibers according to the size of the first fixing ring 1, and arrange them into m rows and n columns, such as 22 rows and 2 columns. Weave a certain length from one side and then fold it in half to form the first fixing ring 1.

[0029] (2) Ply the two ends of the yarn in step (1) together and arrange them into m rows and 2n columns, such as 22 rows and 4 columns. During the weaving process, the number of yarns involved in the weaving remains basically unchanged, and the first strip body 3 is woven. In order to achieve the gradual change in the width and thickness of the first strip body 3, the weaving yarn array needs to be changed gradually. The way the yarn arrangement changes is: from m rows and 2n columns to mk rows and 2n+t columns; such as: from 22 rows and 4 columns to 17 rows and 5 columns. During the arrangement change, If 2*m*n=(mk)*(2n+t), then weave according to this arrangement; If 2*m*n>(mk)*(2n+t), then remove the excess weaving yarn; If 2*m*n < (mk)*(2n+t), then add the corresponding yarn to the corresponding point; For example, in a 17-row, 5-column array, the total number of yarns is 17×5-1=84, which is less than the number of yarns in a 22×4 array, which is 22×4-1=87. Therefore, 3 yarns need to be removed according to the yarn reduction process before weaving. (3) After the first strip body 3 is woven, start weaving the connecting section 5, gradually add m*n floating yarns, such as 44 floating yarns, mark the two ends of each floating yarn, and weave to form the connecting section 5. After weaving, remove m*n (i.e. 44) yarns from the unmarked yarns. (4) After the connecting segment 5 is woven, the second strip body 4 is woven. When weaving the second strip body 4, the yarn arrangement changes as follows: from mk rows and 2n+t columns to m rows and 2n columns, such as from 17 rows and 5 columns to 22 rows and 4 columns; during the arrangement change, If 2*m*n=(mk)*(2n+t), then weave according to this arrangement; If 2*m*n>(mk)*(2n+t), then remove the excess weaving yarn; If 2*m*n < (mk)*(2n+t), then add the corresponding yarn to the corresponding point; (5) After the second strip body 4 is woven, the second fixing ring 2 is woven. Specifically, the m*n floating yarns do not participate in the weaving, and the m*n yarns are woven to a certain length and then folded in half to form the second fixing ring 2. Specifically, the m rows and 2n columns of yarn are divided into m*n yarn groups and m*n floating yarn groups. The m*n (e.g., 22*2) yarns are woven to a certain length and then folded in half to form the second fixing ring 2. (6) After the second fixing ring 2 is woven, the m*n floating yarn ends 61 are connected with the second fixing ring yarn ends 21 of the m*n yarns, and the yarns are pulled through the floating yarns according to the markings on the floating yarns. The corresponding floating yarns are replaced with the yarns to complete the overall weaving of the limiting belt.

[0030] The limiting band woven in this embodiment is a single integral structure, avoiding cutting and sewing processes, and has good integrity. The length direction of the limiting band and the two closed fixing rings of the present invention are woven from a single yarn, resulting in good dimensional stability and no weak points in performance. Under the same performance conditions, the limiting band prepared by the weaving process of the present invention can further reduce the weight of the limiting band. Example 2

[0031] like Figures 1 to 3 As shown, this embodiment provides a process for weaving a limiting band. This embodiment is based on a four-step weaving method, and the specific weaving process is as follows: The limiting belt includes a strip-shaped body and a first fixing ring 1 and a second fixing ring 2 located at both ends of the strip-shaped body, which are woven in the order of "first fixing ring 1 - strip-shaped body - second fixing ring 2"; More specifically, the strip-shaped body includes a first strip-shaped body 3 with decreasing width and increasing thickness, a second strip-shaped body 4 with increasing width and decreasing thickness, and a connecting segment 5 located between the first strip-shaped body 3 and the second strip-shaped body 4; the strips are woven in the order of "first fixing ring 1 - first strip-shaped body 3 - connecting segment 5 - second strip-shaped body 4 - second fixing ring 2". The weaving steps include: (1) Design the required number of fibers according to the size of the first fixing ring 1, and arrange them into m rows and n columns, such as 22 rows and 6 columns, and weave them from both sides to form the first fixing ring 1; (2) Ply the two ends of the yarn in step (1) together and arrange them into 2m rows and n columns, such as 44 rows and 6 columns. During the weaving process, the number of yarns involved in the weaving remains basically unchanged, and the first strip body 3 is woven. In order to achieve the gradual change in the width and thickness of the first strip body 3, the weaving yarn array needs to be changed gradually. The way the yarn arrangement changes is: from 2m rows and n columns to 2m-k rows and n+t columns; such as: from 44 rows and 6 columns to 35 rows and 8 columns. During the arrangement change, If 2*m*n=(mk)*(2n+t), then weave according to this arrangement; If 2*m*n>(mk)*(2n+t), then remove the excess weaving yarn; If 2*m*n < (mk)*(2n+t), then add the corresponding yarn to the corresponding point; For example, in a 35-row, 8-column array, the total number of yarns is 35×8-1=279, which is greater than the number of yarns in a 44×6 array (22×4-1=263). Therefore, 16 yarns need to be added using the yarn reduction process before weaving. (3) After the first strip body 3 is woven, start weaving the connecting section 5, gradually add m*n floating yarns, such as 132 floating yarns, mark the two ends of each floating yarn, and weave to form the connecting section 5. After weaving, remove m*n (i.e. 132) yarns from the unmarked yarns. (4) After the connecting segment 5 is woven, the second strip body 4 is woven. When weaving the second strip body 4, the yarn arrangement changes gradually from 2m-k rows and n+t columns to 2m rows and n columns, such as from 35 rows and 8 columns to 44 rows and 6 columns. During the arrangement change, If 2*m*n = (2m-k)*(n+t), then weave according to this arrangement; If 2*m*n>(2m-k)*(n+t), then remove the excess weaving yarn; If 2*m*n < (2m-k)*(n+t), then add the corresponding yarn to the corresponding point; (5) After the second strip body 4 is woven, the second fixing ring 2 is woven. Specifically, the m*n floating yarns do not participate in the weaving, and the m*n yarns are woven to a certain length and then folded in half to form the second fixing ring 2. Specifically, the 2m rows and n columns of yarns are divided into m*n yarn groups and m*n floating yarn groups. The m*n (e.g., 22*6) yarns are woven to a certain length and then folded in half to form the second fixing ring 2. (6) After the second fixing ring 2 is woven, the m*n floating yarn ends 61 are connected with the second fixing ring yarn ends 21 of the m*n yarns, and the yarns are pulled through the floating yarns according to the markings on the floating yarns. The corresponding floating yarns are replaced with the yarns to complete the overall weaving of the limiting belt.

[0032] The limiting band woven in this embodiment is a single integral structure, avoiding cutting and sewing processes, and has good integrity. The length direction of the limiting band and the two closed fixing rings of the present invention are woven from a single yarn, resulting in good dimensional stability and no weak points in performance. Under the same performance conditions, the limiting band prepared by the weaving process of the present invention can further reduce the weight of the limiting band. Example 3

[0033] This embodiment provides a weaving process for a limiting band, the weaving steps of which include: (1) Design the required number of fibers according to the size of the first fixing ring 1, and arrange them into m rows and n columns, such as 22 rows and 2 columns. Weave a certain length from one side and then fold it in half to form the first fixing ring 1.

[0034] (2) Ply the two ends of the yarn in step (1) together and arrange them into m rows and 2n columns, such as 22 rows and 4 columns. During the weaving process, the number of yarns involved in the weaving remains basically unchanged, and the first strip body 3 is woven. In order to achieve the gradual change in the width and thickness of the first strip body 3, the weaving yarn array needs to be changed gradually. The way the yarn arrangement changes is: from m rows and 2n columns to mk rows and 2n+t columns; such as: from 22 rows and 4 columns to 11 rows and 8 columns. During the arrangement change, If 2*m*n=(mk)*(2n+t), then weave according to this arrangement; If 2*m*n>(mk)*(2n+t), then remove the excess weaving yarn; If 2*m*n < (mk)*(2n+t), then add the corresponding yarn to the corresponding point; For example, in an "11 rows and 8 columns" array, the total number of yarns is 11×8-1=87, which is less than the number of yarns in a "22×4" array, which is 22×4-1=87. Therefore, weaving can be done in this arrangement. (3) After the first strip body 3 is woven, start weaving the connecting section 5, gradually add m*n floating yarns, such as 44 floating yarns, mark the two ends of each floating yarn, and weave to form the connecting section 5. After weaving, remove m*n (i.e. 44) yarns from the unmarked yarns. (4) After the connecting segment 5 is woven, the second strip body 4 is woven. When weaving the second strip body 4, the yarn arrangement changes as follows: from mk rows and 2n+t columns to m rows and 2n columns, such as from 11 rows and 8 columns to 22 rows and 4 columns; during the arrangement change, If 2*m*n=(mk)*(2n+t), then weave according to this arrangement; If 2*m*n>(mk)*(2n+t), then remove the excess weaving yarn; If 2*m*n < (mk)*(2n+t), then add the corresponding yarn to the corresponding point; (5) After the second strip body 4 is woven, the second fixing ring 2 is woven. Specifically, the m*n floating yarns do not participate in the weaving, and the m*n yarns are woven to a certain length and then folded in half to form the second fixing ring 2. Specifically, the m rows and 2n columns of yarn are divided into m*n yarn groups and m*n floating yarn groups. The m*n (e.g., 22*2) yarns are woven to a certain length and then folded in half to form the second fixing ring 2. (6) After the second fixing ring 2 is woven, the m*n floating yarn ends 61 are connected with the second fixing ring yarn ends 21 of the m*n yarns, and the yarns are pulled through the floating yarns according to the markings on the floating yarns. The corresponding floating yarns are replaced with the yarns to complete the overall weaving of the limiting belt.

[0035] The limiting band woven in this embodiment is a single integral structure, avoiding cutting and sewing processes, and has good integrity. The length direction of the limiting band and the two closed fixing rings of the present invention are woven from a single yarn, resulting in good dimensional stability and no weak points in performance. Under the same performance conditions, the limiting band prepared by the weaving process of the present invention can further reduce the weight of the limiting band. Example 4
