[0032] 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 some embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] As mentioned earlier, this solution divides a single weaving machine into multiple groups of weaving spindles and achieves the preparation of multi-layer fabrics through the synchronous movement of multiple groups of spindles, thereby improving the weaving efficiency of multi-layer two-dimensional fabrics. Since the number of yarn layers and weaving length of each fabric layer can be controlled independently, the fabric thickness can be varied along the weaving length direction. At the same time, the number of rows of each group of spindles can be designed, so the weaving angle of the inner and outer layers of the fabric can be adjusted, the thickness of a single layer of fabric can be varied, and the fabric has strong design flexibility.

[0034] The following describes the specific implementation of the above concept.

[0035] Please refer to Figure 1 This invention provides a method for the synchronous forming of two-dimensional multilayer fabrics, the method comprising:

[0036] Step 100: Obtain the fabric type and physical parameters of the two-dimensional multilayer fabric to be woven;

[0037] Step 102: Group the weaving machines based on the number of fabric layers to obtain a standard weaving machine with n layers of spindles in each group;

[0038] Step 104: Install the yarn into the standard braiding machine according to the preset plan;

[0039] Step 106: Based on the fabric type, the yarn is woven using spindles to obtain the two-dimensional multilayer fabric to be woven.

[0040] In this embodiment of the invention, by dividing a single weaving machine into multiple groups of weaving spindles and achieving the synchronous movement of these multiple groups of spindles, the weaving efficiency of multi-layer two-dimensional fabrics is improved. Since the number of yarn layers and the weaving length of each fabric layer can be controlled independently, the fabric thickness can be varied along the weaving length direction. At the same time, the number of rows in each group of spindles can be designed, so the weaving angle of the inner and outer layers of the fabric can be adjusted, the thickness of a single fabric layer can be varied, and the fabric has strong design flexibility.

[0041] The following description Figure 1 The execution method of each step is shown.

[0042] First, for step 100, obtain the fabric type and physical parameters of the two-dimensional multilayer fabric to be woven.

[0043] Two-dimensional woven fabrics, due to their designable weaving angles and ability to be sized to net dimensions, have resulted in composite materials reinforced with them exhibiting high specific strength, high specific modulus, impact resistance, and fatigue resistance, making them a promising lightweight structural material. To ensure that the fabric's inherent properties are not affected during the weaving process, the weaving machine needs to be assembled and processed before weaving, based on the type and physical parameters of the two-dimensional multilayer fabric to be woven.

[0044] Specifically, the fabric types are divided into rectangular cross-section fabrics and rotary cross-section fabrics. Technicians can distribute the weaving machines according to the fabric type, and splice the shapes of the weaving machines to match or be similar to the shape of the fabric, thus facilitating subsequent weaving processes. At the same time, the spindles on each weaving machine are grouped according to the physical parameters of the two-dimensional multi-layer fabric to be woven, including the number of fabric layers, fabric length, fabric thickness, etc.

[0045] Then, for step 102, the weaving machines are grouped based on the number of fabric layers to obtain standard weaving machines with n layers of spindles in each group.

[0046] In this embodiment of the invention, in order to improve the weaving efficiency of each layer of a multi-layered fabric, the spindles of the weaving machine need to be grouped according to the number of layers of the fabric. The number of spindle groups is the same as the number of layers of the fabric. For example, a four-layered fabric is divided into four groups of spindles, a three-layered fabric is divided into three groups of spindles, and so on. At the same time, each group of spindles is layered according to the required thickness of each layer of fabric, that is, the number of spindle layers is determined by the fabric thickness, thus obtaining a standard weaving machine with n layers of spindles in each group, where n is a positive odd number greater than 1. For example, when the thickness of the first layer of fabric is 0.5mm, the corresponding first group of spindles can contain 3 layers of spindles, and when the thickness of the second layer of fabric is 0.8mm, the corresponding second group of spindles can contain 5 layers of spindles.

[0047] It is worth noting that the above-described division of the weaving machine is the optimal embodiment provided by the present invention. The specific number of layers in each group of spindles can be adjusted by those skilled in the art according to actual needs, and will not be elaborated here.

[0048] For step 104, the yarn is installed onto the standard braiding machine according to the preset scheme.

[0049] In this embodiment of the invention, the yarn is installed according to the following rules: each group of spindles is installed according to the first layer to the... Layers with a spindle spaced apart, the first The nth layer is separated by a spindle for yarn hanging and the nth layer All layers are covered with gauze; from the first layer to the... The yarn of the first layer and the second layer The yarns from layer n to layer n are not in the same column. For example, if a set of spindles is divided into 7 layers, then the spindles in layers 1 to 3 and layers 5 to 7 are all hung with yarn, with every other spindle in layer 5, and all spindles in layer 4 are hung with yarn. Also, the yarns from layers 1 to 3 and layers 5 to 7 are not in the same column.

[0050] Furthermore, when the two-dimensional multilayer fabric to be woven is a rectangular cross-section fabric, in the first... Add m spindles to either the left or right end of the layered yarn spindle, while leaving the other end unchanged. Here, m is any positive integer. Changing the number of m allows the weaving machine to alter the weaving angle of the fabric during the weaving process. The aforementioned number of m can be adjusted by those skilled in the art based on the actual weaving angle of the fabric, and is not specifically limited here.

[0051] Furthermore, when the two-dimensional multilayer fabric to be woven is a rectangular cross-section fabric, the first... The number of spindles in a layer can be either odd or even, but when the two-dimensional multilayer fabric to be woven is a fabric with a rotating cross section, the number of spindles in the first layer is greater than the number of spindles in the second layer. The number of layered yarn spindles is always an even number.

[0052] For step 106, based on the fabric type, the yarn is woven using spindles to obtain the two-dimensional multilayer fabric to be woven.

[0053] To ensure that the fabric woven by the weaving machine meets the pre-defined requirements to the greatest extent possible, different motion schemes need to be selected for the spindles according to the type of fabric to be woven.

[0054] Specifically, when the two-dimensional multilayer fabric to be woven is a rectangular cross-section fabric, the spindle is instructed to execute a first motion scheme; the first motion scheme is repeated until the two-dimensional multilayer fabric to be woven meets the fabric length requirement; wherein, the first motion scheme includes moving the first... The first layer of yarn spindles moves m units to the side where m spindles have not been added, from the first layer to the second layer. Layered yarn spindles and the first Layered yarn spindles in the same column Layered yarn spindles move downwards Unit, No. Layer n to layer n spindles and with the first Layered yarn spindles in the same column Layered yarn spindles move upwards Unit; the first The first layer of yarn spindles moves m units in the opposite direction. Layered yarn spindles and the first Layered yarn spindles in the same column Layered yarn spindles move upwards Unit, No. Layer to the nth layer and with the nth layer Layered yarn spindles in the same column Layered yarn spindles move downwards Units;

[0055] When the two-dimensional multilayer fabric to be woven is a rotary cross-section fabric, the spindle is instructed to execute the second motion scheme; the second motion scheme is repeated until the two-dimensional multilayer fabric to be woven meets the fabric length requirement; wherein, the second motion scheme includes moving the first... The yarn spindles move clockwise by any positive integer number of units, from the first layer to the second layer. Layered yarn spindles and the first Layered yarn spindles in the same column The layered spindles move away from the center. Unit, No. Layer n to layer n spindles and with the first Layered yarn spindles in the same column The layered spindles move towards the center of the circle. Unit; the first The yarn spindles move in a counterclockwise direction for any positive integer number of units, from the first layer to the second layer. Layered yarn spindles and the first Layered yarn spindles in the same column The layered spindles move towards the center of the circle. Unit, No. Layer n to layer n spindles and with the first Layered yarn spindles in the same column The layered spindles move away from the center. Units.

[0056] Considering that when weaving multi-layered fabrics, if the number of spindle rows on the weaving machine remains unchanged, that is, the number of spindles in the inner and outer layers is the same, it will inevitably cause uneven density between the inner and outer layers of the fabric. Therefore, in this embodiment of the invention, the number of rows in each group of spindles is different, and thus the number of yarns on each group of spindles is also different. This can effectively reduce the density difference caused by changes in the diameter or circumference of the inner and outer layers, making the yarn distribution in the fabric more uniform.

[0057] In this embodiment of the invention, each layer of spindles in the same group moves simultaneously, and each group of spindles moves independently. This allows for independent control of the weaving length of each layer of fabric, thereby effectively controlling the thickness variation of the fabric along the weaving length direction. Furthermore, since the woven fabric is multi-layered, at least two groups of spindles must move simultaneously.

[0058] It is worth noting that by adding axial spindles between two adjacent layers of spindles in each group of spindles, it is possible to achieve synchronous forming of two-dimensional triaxial fabrics.

[0059] The above weaving process will be explained below with reference to two preferred embodiments of the present invention:

[0060] Example 1:

[0061] This embodiment provides a two-dimensional three-layer flat fiberglass fabric, such as Figure 2 As shown. The first layer of fabric has a weave angle of 48°, a single layer thickness of 0.5 mm, and a length of 900 mm; the second layer of fabric has a weave angle of 73°, a single layer thickness of 1.5 mm, and a length of 900 mm; the third layer of fabric has a weave angle of 65°, and the single layer thickness decreases successively from 1.6 mm to 1.1 mm, 0.7 mm, and finally 0 mm, with a length of 450 mm. Its preparation method includes the following steps.

[0062] Weaving machine distribution: Since the fabric to be produced is a rectangular cross-section fabric, a square weaving machine can be directly selected.

[0063] The number of layers in the weaving machine is divided as follows: The fabric consists of three layers in total. The first layer contains 3 spindles, the second layer contains 5 spindles, and the third layer contains 7 spindles.

[0064] Hanging gauze: such as Figure 3 As shown, where:

[0065] First layer of fabric: The first and third layers use alternate yarn hanging, and the second layer is all yarn hanging. The yarn hanging in the first and third layers is not in the same column, and an additional yarn is added to the right side of the second layer.

[0066] Second layer of fabric: The first, second and fourth and fifth layers use intermittent yarn hanging, and the third layer is all yarn hanging. Among them, the yarns hanging in the first, second and fourth and fifth layers are not in the same column, and three additional yarns are added to the right side of the third layer.

[0067] The third layer of fabric: layers 1, 2, 3 and layers 5, 6, 7 use intermittent yarn hanging, and layer 4 is entirely yarn hanging. Among them, the yarns hanging in layers 1, 2, 3 and layers 5, 6, 7 are not in the same column, and two additional yarns are added to the right side of layer 4.

[0068] The movement of the yarn spindles in each layer of fabric is as follows:

[0069] Layer 1 fabric: Layer 2 spindles move 1 unit to the right, Layer 1 spindles and Layer 2 spindles in the same column as Layer 1 spindles move 1 unit downwards, Layer 3 spindles and Layer 2 spindles in the same column as Layer 3 spindles move 1 unit upwards, such as... Figure 4 As shown; the second layer spindle moves 1 unit to the left, the first layer spindle and the second layer spindle in the same column as the first layer spindle move 1 unit downwards, and the third layer spindle and the second layer spindle in the same column as the third layer spindle move 1 unit upwards, as follows. Figure 3 As shown.

[0070] Second layer of fabric: The third layer spindle moves 3 units to the right; the first and second layer spindles, as well as the third layer spindle in the same column as the first layer spindle, move 2 units downward; the fourth and fifth layer spindles, as well as the third layer spindle in the same column as the fourth layer spindle, move 2 units upward. Figure 4 As shown; the third layer spindle moves 3 units to the left, the first and second layer spindles, and the third layer spindle in the same column as the first layer spindle, move 2 units downwards, and the fourth and fifth layer spindles, and the third layer spindle in the same column as the fourth layer spindle, move 2 units upwards, as shown. Figure 3 As shown.

[0071] Layer 3 fabric: Layer 4 spindles move 2 units to the right; Layers 1, 2, and 3 spindles, as well as Layer 4 spindles in the same column as Layer 1 spindles, move 3 units downwards; Layers 5, 6, and 7 spindles, as well as Layer 4 spindles in the same column as Layer 5 spindles, move 3 units upwards. Figure 4 As shown; the 4th layer spindle moves 2 units to the left, the 1st, 2nd, and 3rd layer spindles, as well as the 4th layer spindle in the same column as the 1st layer spindle, move 3 units downwards, and the 5th, 6th, and 7th layer spindles, as well as the 4th layer spindle in the same column as the 5th layer spindle, move 3 units upwards, as... Figure 3 As shown.

[0072] Repeat the above spindle movement process until the yarn reaches a length of 150mm. Then, remove the yarn from the first and seventh layers of the third set of spindles. Figure 5 As shown. The movement of the spindles in the third layer of fabric is changed as follows: the third layer spindle moves 2 units to the right; the first and second layer spindles, as well as the third layer spindle in the same column as the first layer spindle, move 2 units downward; the fourth and fifth layer spindles, as well as the third layer spindle in the same column as the fourth layer spindle, move 2 units upward. Figure 6 As shown; the third layer spindle moves 2 units to the left, the first and second layer spindles, and the third layer spindle in the same column as the first layer spindle, move 2 units downwards, and the fourth and fifth layer spindles, and the third layer spindle in the same column as the fourth layer spindle, move 2 units upwards, as shown. Figure 5 As shown.

[0073] Furthermore, when the yarn reaches a length of 300mm, remove the yarns from the first and fifth layers on the third set of spindles, as follows: Figure 7 As shown. The movement of the spindles in the third layer of fabric is changed as follows: the spindles in the second layer move 2 units to the right, the spindles in the first layer and the spindles in the second layer (which are in the same column as the first layer) move 1 unit downwards, and the spindles in the third layer and the spindles in the second layer (which are in the same column as the third layer) move 1 unit upwards, as shown. Figure 8 As shown; the second layer spindle moves 2 units to the left, the first layer spindle and the second layer spindle in the same column as the first layer spindle move 1 unit downwards, and the third layer spindle and the second layer spindle in the same column as the third layer spindle move 1 unit upwards, as follows. Figure 7 As shown.

[0074] Furthermore, when the yarn reaches a length of 450mm, remove all yarn from the third set of spindles, such as... Figure 9 As shown.

[0075] The first and second groups of yarns continue to be woven to a length of 900mm, thus obtaining a two-dimensional three-layer flat fabric.

[0076] Example 2:

[0077] like Figure 10 As shown, Figure 10 This is a schematic diagram of the external shape of a rotary cross-section fabric provided in an embodiment of the present invention (a double-layer two-dimensional triaxial hollow circular tube fabric, wherein the innermost layer is quartz fiber and the outermost layer is carbon fiber).

[0078] like Figure 11 As shown, Figure 11This is a schematic diagram showing the distribution of spindles on a weaving machine for a rotary cross-section fabric according to an embodiment of the present invention. Since a circular cross-section is being prepared, a circular weaving machine can be directly selected. Six layers of spindles are selected on the weaving machine, grouped in three layers. In each group of spindles, the first and third layers are alternately yarn-loaded, while the second layer is entirely yarn-loaded. The yarns in the first and third layers are not in the same column. Furthermore, to improve the tensile properties of the material, an axial yarn layer is added between adjacent yarn layers.

[0079] Furthermore, in groups, each group of spindles moves synchronously: the second layer spindle moves clockwise by one unit; the first layer spindle and the second layer spindle in the same column as the first layer spindle move one unit away from the center; the third layer spindle and the second layer spindle in the same column as the third layer spindle move one unit closer to the center, and so on. Figure 12 As shown; the second layer spindle moves counterclockwise by 1 unit, the first layer spindle and the second layer spindle in the same column as the first layer spindle move 1 unit away from the center, and the third layer spindle and the second layer spindle in the same column as the third layer spindle move 1 unit closer to the center, as shown. Figure 11 As shown.

[0080] Repeat the above process steps for each group of spindles until 200mm, and you will get a double-layer two-dimensional triaxial hollow tube fabric.

[0081] In summary, by dividing a single weaving machine into multiple groups of weaving spindles and achieving the synchronous movement of these spindles to prepare multi-layer fabrics, the weaving efficiency of multi-layer two-dimensional fabrics is improved. Since the number of yarn layers and the weaving length of each fabric layer can be controlled independently, the fabric thickness can be varied along the weaving length direction. At the same time, the number of rows in each group of spindles can be designed, so the weaving angle of the inner and outer layers of the fabric can be adjusted, the thickness of a single layer of fabric can be varied, and the fabric has strong design flexibility.
