Description

Technical Field

[0001] The invention belongs to the field of weaving technology, and specifically relates to a limiting belt and a three-dimensional weaving technology and application thereof. Background Art

[0002] Textile composites are advanced composite materials that are reinforced with textile fibers and their structures. Three-dimensional woven composites are an important branch of textile structural composites. They use three-dimensional weaving technology to weave the reinforcing fibers into a three-dimensional integral fabric, and then compound it with a matrix (including resin, carbon, silicon carbide, metal, etc.) to make a three-dimensional woven composite product.

[0003] The biggest feature of three-dimensional braided fabrics is that there is no concept of layers. Three-dimensional braided fabrics are formed in one piece, so three-dimensional braided 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 braided composite materials to make main load-bearing structural parts and reinforcements of load-bearing structural parts.

[0004] At present, my country's aerospace, aviation, medical and other fields are in urgent need of various high-performance and functional three-dimensional woven composite special-shaped parts, so further research on three-dimensional weaving technology and three-dimensional woven composite materials for special-shaped parts is of great significance to the development of my country's new materials field.

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

[0006] The purpose of the invention is to overcome the problems of poor mechanical properties, low strength and the need for later cutting and sewing of existing three-dimensional woven composite materials, and to provide a limiting belt and its three-dimensional weaving process and application, so that the limiting belt has excellent mechanical properties, simple process, and does not require later cutting and sewing, thereby improving the overall performance of the limiting belt.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] A three-dimensional braided limiting belt process, the limiting belt comprises a belt-shaped body and a first and a second fixing ring respectively located at two ends of the belt-shaped body, and is braided in the order of the first fixing ring-belt-shaped body-second fixing ring.

[0009] The limiting belt woven by the weaving process of the present invention is an integral structure, avoiding the processes of cutting and sewing, and has good integrity; the length direction and two closed fixing rings of the limiting belt of the present invention are woven with a whole yarn, with good dimensional stability and no performance weaknesses; under the same performance conditions, the limiting belt prepared by the weaving process of the present invention can further reduce the weight of the limiting belt; in addition, the weaving process of the present invention can be used to weave components with similar shapes to the limiting belt of the present invention, and are widely used in aviation, aerospace, energy, transportation, sports and other fields to achieve the purpose of increasing strength and reducing weight.

[0010] 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 weaving from one side for a certain length and then folding in half to form the first fixing loop; and / or controlling weaving from both sides to form the first fixing loop.

[0011] The weaving process of the first fixing ring is simple, and after the first fixing ring is woven, the weaving of the belt-shaped main body can continue, without the need to sew the first fixing ring and the belt-shaped main body separately, thus simplifying the production process.

[0012] Furthermore, the braiding of the belt-like main body comprises: after the first fixed loop is braided, the two ends of the yarn are stranded and arranged into m rows and 2n columns, or 2m rows and n columns, and braided to form the belt-like main body.

[0013] Furthermore, the strip-shaped body comprises a first strip-shaped body with reduced width and increased thickness and a second strip-shaped body with increased width and reduced thickness.

[0014] During the weaving process, the number of yarns involved in weaving remains unchanged. First, the arrangement of the yarns is adjusted by reducing the number of row yarns and increasing the number of column yarns to weave a first strip-shaped body, and then the arrangement of the yarns is increased by increasing the number of row yarns and reducing the number of column yarns to weave a second strip-shaped body.

[0015] The number of yarns involved in weaving remains basically unchanged, so that the outer surface of the limiting belt formed by weaving does not produce obvious edges and corners, ensuring the smoothness of the surface of the limiting belt.

[0016] Furthermore, when weaving the first belt-shaped body, the arrangement of the yarn changes from m rows and 2n columns to mk rows and 2n+t columns, and when weaving the second belt-shaped body, the arrangement of the yarn changes from mk rows and 2n+t columns to m rows and 2n columns;

[0017] Alternatively, when weaving the first strip-shaped body, the arrangement of the yarn changes from 2m rows and n columns to 2m-k rows and n+t columns, and when weaving the second strip-shaped body, the arrangement of the yarn changes from 2m-k rows and n+t columns to 2m rows and n columns.

[0018] Furthermore, during the arrangement change process,

[0019] If 2*m*n=(mk)*(2n+t), weave in this arrangement;

[0020] If 2*m*n>(mk)*(2n+t), remove the excess braiding yarn;

[0021] If 2*m*n<(mk)*(2n+t), then add the corresponding yarn to the corresponding point;

[0022] or,

[0023] If 2*m*n=(2m-k)*(n+t), weave in this arrangement;

[0024] If 2*m*n>(2m-k)*(n+t), remove the excess yarn;

[0025] If 2*m*n<(2m-k)*(n+t), then add the corresponding yarn to the corresponding point.

[0026] Furthermore, there is a connecting section between the first and second belt-shaped bodies, and the braiding is carried out in the order of the first belt-shaped body-connecting section-second belt-shaped body;

[0027] Preferably, weaving the connecting section includes: after the first strip-shaped main body is woven, gradually adding m*n floating yarns, marking both ends of each floating yarn, weaving to form a connecting section, and after the weaving is completed, removing m*n yarns from the unmarked yarns.

[0028] Further, after the connection section is woven, the m*n floating yarns do not participate in the weaving, and the m*n yarns are folded in half after being woven for a certain length to form the second fixing ring;

[0029] Preferably, after the second fixed loop is woven, the ends of the m*n floating yarns are butt-jointed with the ends of the m*n yarns, and the yarns are pulled through the floating yarns according to the marks of the floating yarns, and the corresponding floating yarns are replaced with the yarns to complete the overall weaving of the limiting belt.

[0030] The present invention provides a three-dimensional woven limiting belt woven by adopting the woven process described in any one of the above technical solutions.

[0031] The three-dimensional braided limiting belt of the present invention is applied in the fields of aviation, aerospace, energy, transportation and sports.

[0032] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0033] The limiting belt woven by the weaving process of the present invention is an integral structure, avoiding the processes of cutting and sewing, and has good integrity; the length direction and two closed fixing rings of the limiting belt of the present invention are woven with a whole yarn, with good dimensional stability and no performance weaknesses; under the same performance conditions, the limiting belt prepared by the weaving process of the present invention can further reduce the weight of the limiting belt; in addition, the weaving process of the present invention can be used to weave components with similar shapes to the limiting belt of the present invention, and are widely used in aviation, aerospace, energy, transportation, sports and other fields to achieve the purpose of increasing strength and reducing weight.

[0045] Embodiment 1

[0046] like Figures 1 to 3 As shown, this embodiment provides a process for weaving a limiting belt. This embodiment is based on a four-step method for weaving. The specific weaving process is as follows:

[0047] The limiting belt includes a belt-shaped body and a first fixing ring 1 and a second fixing ring 2 respectively located at two ends of the belt-shaped body, and is woven in the order of "first fixing ring 1-belt-shaped body-second fixing ring 2";

[0048] More specifically, the strip body includes a first strip body 3 with reduced width and increased thickness, a second strip body 4 with increased width and reduced thickness, and a connecting section 5 between the first strip body 3 and the second strip body 4; the strip body is woven in the order of "first fixing ring 1-first strip body 3-connecting section 5-second strip body 4-second fixing ring 2". The weaving steps include:

[0049] (1) Design the required number of fibers according to the size of the first fixing loop 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 loop 1.

[0050] (2) The two ends of the yarn in step (1) are stranded and arranged 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-shaped body 3 is weaved. In order to achieve a gradual change in the width and thickness of the first strip-shaped body 3, the weaving yarn array is gradually changed, and the arrangement of the yarn is changed in the following manner: from m rows and 2n columns to mk rows and 2n+t columns; for example, from 22 rows and 4 columns to 17 rows and 5 columns;

[0051] During the arrangement change process,

[0052] If 2*m*n=(mk)*(2n+t), weave in this arrangement;

[0053] If 2*m*n>(mk)*(2n+t), remove the excess braiding yarn;

[0054] If 2*m*n<(mk)*(2n+t), then add the corresponding yarn to the corresponding point;

[0055] For example, in the array of "17 rows and 5 columns", the total number of yarns is 17×5-1=84, which is less than the number of yarns in the 22×4 array (22×4-1=87), so 3 yarns need to be removed according to the yarn reduction process before weaving;

[0056] (3) After the first strip-shaped body 3 is woven, the connecting section 5 is woven, and m*n floating yarns are gradually added, such as 44 floating yarns. Both ends of each floating yarn are marked, and the connecting section 5 is woven. After the weaving is completed, m*n (i.e., 44) yarns are removed from the unmarked yarns;

[0057] (4) After the connection section 5 is woven, the second belt-shaped body 4 is woven. When the second belt-shaped body 4 is woven, the arrangement of the yarns is changed 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,

[0058] If 2*m*n=(mk)*(2n+t), weave in this arrangement;

[0059] If 2*m*n>(mk)*(2n+t), remove the excess braiding yarn;

[0060] If 2*m*n<(mk)*(2n+t), then add the corresponding yarn to the corresponding point;

[0061] (5) After the second strip-shaped body 4 is woven, the second fixing loop 2 is woven, which specifically includes: m*n floating yarns are not woven, and the m*n yarns are woven for a certain length and then folded in half to form the second fixing loop 2; specifically, the m rows and 2n columns of yarns are divided into m*n yarn groups and m*n floating yarn groups, and the m*n (e.g., 22*2) yarns are woven for a certain length and then folded in half to form the second fixing loop 2;

[0062] (6) After the second fixed ring 2 is woven, the m*n floating yarn ends 61 are connected to the second fixed ring yarn ends 21 of the m*n yarns, and the yarns are pulled through the floating yarns according to the marks of the floating yarns, and the corresponding floating yarns are replaced with the yarns to complete the overall weaving of the limiting belt.

[0063] The limiting belt woven in this embodiment is an integral structure, which avoids the processes of cutting and sewing and has good integrity; the length direction and two closed fixing rings of the limiting belt of the present invention are woven with a whole yarn, with good dimensional stability and no performance weaknesses; under the same performance conditions, the limiting belt prepared by the weaving process of the present invention can further reduce the weight of the limiting belt.

[0064] Embodiment 2

[0065] like Figures 1 to 3 As shown, this embodiment provides a process for weaving a limiting belt. This embodiment is based on a four-step method for weaving. The specific weaving process is as follows:

[0066] The limiting belt includes a belt-shaped body and a first fixing ring 1 and a second fixing ring 2 respectively located at two ends of the belt-shaped body, and is woven in the order of "first fixing ring 1-belt-shaped body-second fixing ring 2";

[0067] More specifically, the strip body includes a first strip body 3 with reduced width and increased thickness, a second strip body 4 with increased width and reduced thickness, and a connecting section 5 between the first strip body 3 and the second strip body 4; the strip body is woven in the order of "first fixing ring 1-first strip body 3-connecting section 5-second strip body 4-second fixing ring 2". The weaving steps include:

[0068] (1) Designing a required number of fibers according to the size of the first fixing ring 1 and arranging them into m rows and n columns, such as 22 rows and 6 columns, and weaving them from both sides to form the first fixing ring 1;

[0069] (2) The two ends of the yarn in step (1) are stranded and arranged 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-shaped body 3 is weaved; in order to achieve a gradual change in the width and thickness of the first strip-shaped body 3, the weaving yarn array is gradually changed, and the arrangement of the yarn is changed in the following manner: from 2m rows and n columns to 2m-k rows and n+t columns; for example, from 44 rows and 6 columns to 35 rows and 8 columns;

[0070] During the arrangement change process,

[0071] If 2*m*n=(mk)*(2n+t), weave in this arrangement;

[0072] If 2*m*n>(mk)*(2n+t), remove the excess braiding yarn;

[0073] If 2*m*n<(mk)*(2n+t), then add the corresponding yarn to the corresponding point;

[0074] For example, in the array of "35 rows and 8 columns", the total number of yarns is 35×8-1=279, which is greater than the number of yarns in the 44×6 array (22×4-1=263), so 16 yarns need to be added according to the yarn reduction process and then knitted;

[0075] (3) After the first strip-shaped body 3 is woven, the connecting section 5 is woven, and m*n floating yarns are gradually added, such as 132 floating yarns. Both ends of each floating yarn are marked, and the connecting section 5 is woven. After the weaving is completed, m*n (i.e., 132) yarns are removed from the unmarked yarns;

[0076] (4) After the connection section 5 is woven, the second belt-shaped body 4 is woven. When the second belt-shaped body 4 is woven, the arrangement of the yarns is changed from 2m-k rows and n+t columns to 2m rows and n columns, such as 35 rows and 8 columns to 44 rows and 6 columns. During the arrangement change,

[0077] If 2*m*n=(2m-k)*(n+t), weave in this arrangement;

[0078] If 2*m*n>(2m-k)*(n+t), remove the excess braiding yarn;

[0079] If 2*m*n<(2m-k)*(n+t), then add the corresponding yarn to the corresponding point;

[0080] (5) After the second strip-shaped body 4 is woven, the second fixing loop 2 is woven, which specifically includes: m*n floating yarns are not woven, and the m*n yarns are woven for a certain length and then folded in half to form the second fixing loop 2; specifically, 2m rows and n columns of yarns are divided into m*n yarn groups and m*n floating yarn groups, and m*n (such as 22*6) yarns are woven for a certain length and then folded in half to form the second fixing loop 2;

[0081] (6) After the second fixed ring 2 is woven, the m*n floating yarn ends 61 are connected to the second fixed ring yarn ends 21 of the m*n yarns, and the yarns are pulled through the floating yarns according to the marks of the floating yarns, and the corresponding floating yarns are replaced with the yarns to complete the overall weaving of the limiting belt.

[0082] The limiting belt woven in this embodiment is an integral structure, which avoids the processes of cutting and sewing and has good integrity; the length direction and two closed fixing rings of the limiting belt of the present invention are woven with a whole yarn, with good dimensional stability and no performance weaknesses; under the same performance conditions, the limiting belt prepared by the weaving process of the present invention can further reduce the weight of the limiting belt.

[0083] Embodiment 3

[0084] This embodiment provides a weaving process for a limiting belt, and the weaving steps include:

[0085] (1) Design the required number of fibers according to the size of the first fixing loop 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 loop 1.

[0086] (2) The two ends of the yarn in step (1) are stranded and arranged 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-shaped body 3 is weaved. In order to achieve a gradual change in the width and thickness of the first strip-shaped body 3, the weaving yarn array is gradually changed, and the arrangement of the yarn is changed in the following manner: from m rows and 2n columns to mk rows and 2n+t columns; for example, from 22 rows and 4 columns to 11 rows and 8 columns;

[0087] During the arrangement change process,

[0088] If 2*m*n=(mk)*(2n+t), weave in this arrangement;

[0089] If 2*m*n>(mk)*(2n+t), remove the excess braiding yarn;

[0090] If 2*m*n<(mk)*(2n+t), then add the corresponding yarn to the corresponding point;

[0091] For example, in the "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 the 22×4 array (22×4-1=87), so weaving can be done in this arrangement;

[0092] (3) After the first strip-shaped body 3 is woven, the connecting section 5 is woven, and m*n floating yarns are gradually added, such as 44 floating yarns. Both ends of each floating yarn are marked, and the connecting section 5 is woven. After the weaving is completed, m*n (i.e., 44) yarns are removed from the unmarked yarns;

[0093] (4) After the connection section 5 is woven, the second belt-shaped body 4 is woven. When the second belt-shaped body 4 is woven, the arrangement of the yarns is changed 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,

[0094] If 2*m*n=(mk)*(2n+t), weave in this arrangement;

[0095] If 2*m*n>(mk)*(2n+t), remove the excess braiding yarn;

[0096] If 2*m*n<(mk)*(2n+t), then add the corresponding yarn to the corresponding point;

[0097] (5) After the second strip-shaped body 4 is woven, the second fixing loop 2 is woven, which specifically includes: m*n floating yarns are not woven, and the m*n yarns are woven for a certain length and then folded in half to form the second fixing loop 2; specifically, the m rows and 2n columns of yarns are divided into m*n yarn groups and m*n floating yarn groups, and the m*n (e.g., 22*2) yarns are woven for a certain length and then folded in half to form the second fixing loop 2;

[0098] (6) After the second fixed ring 2 is woven, the m*n floating yarn ends 61 are connected to the second fixed ring yarn ends 21 of the m*n yarns, and the yarns are pulled through the floating yarns according to the marks of the floating yarns, and the corresponding floating yarns are replaced with the yarns to complete the overall weaving of the limiting belt.

[0099] The limiting belt woven in this embodiment is an integral structure, which avoids the processes of cutting and sewing and has good integrity; the length direction and two closed fixing rings of the limiting belt of the present invention are woven with a whole yarn, with good dimensional stability and no performance weaknesses; under the same performance conditions, the limiting belt prepared by the weaving process of the present invention can further reduce the weight of the limiting belt.

Figure 2 As shown, the first fixing ring 1 and the second fixing ring 2 of the limiting belt can be respectively installed on the mounting portion 7 for user convenience.

[0102] In this embodiment, the limiting belt is an integral structure, and no cutting and sewing processes are required during the formation process, and the integrity is good. In this embodiment, the limiting belt in the length direction and the first fixing ring 1 and the second fixing ring 2 are all woven with a whole yarn, with good dimensional stability and no performance weaknesses.

Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
