Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of carbon fiber tubes, and particularly relates to a method for winding carbon fiber tubes with fiber cloth. Background Technology
[0002] Carbon fiber refers to high-strength, high-modulus fibers with a carbon content of over 90%, possessing excellent high-temperature resistance. It is produced from acrylic and viscose fibers through high-temperature oxidation and carbonization, making it an excellent material for manufacturing high-tech equipment in aerospace and other applications. The main uses of carbon fiber are in the manufacture of advanced composite materials and in enhancing the properties of composites with resins, metals, ceramics, and carbon.
[0003] Carbon fiber robotic arms are the most widely used automated mechanical devices in the field of robotics. Although they vary in form, they all share a common characteristic: by receiving commands, they can precisely position themselves at a point in three-dimensional (or two-dimensional) space to perform tasks. Robotic arms generally have three types of movements: extension, rotation, and lifting. Rotation and lifting are accomplished by the horizontal arm and the column. The basic function of the arm is to move the gripper to the required position and to bear the maximum weight of the workpiece being grasped, as well as the weight of the arm itself. In addition, piping, cooling devices, stroke positioning devices, and automatic detection devices are generally also mounted on the arm. Therefore, the arm's structure, working range, load-bearing capacity, and motion accuracy directly affect the overall performance of the machine. Meanwhile, support arms made of carbon fiber have several advantages: lightweight, flexible and accurate operation, high strength, good temperature resistance, and cost-effectiveness.
[0004] Carbon fiber tubes are mainly used in carbon fiber robotic arms. CN113085217A discloses a method for preparing carbon fiber tubes, which includes the following steps: (1) pre-treating a carbon fiber pultruded plate; (2) sequentially laying a first prepreg and a carbon fiber pultruded plate on a mandrel, bonding the first prepreg and the carbon fiber pultruded plate together, and then sequentially laying a second prepreg and a release film; (3) then sequentially undergoing hot pressing, tube winding, mandrel removal, surface treatment, machining, and cleaning to obtain a carbon fiber tube. Tube winding involves sequentially winding carbon fiber cloth onto the surface of the mandrel after hot pressing in a predetermined order.
[0005] However, the above-mentioned tube winding method is mainly applicable to carbon fiber tubes with a single structure, and is not applicable to carbon fiber tubes with a composite structure. It is easy to cause the roundness and thickness of the carbon fiber tubes with a composite structure to be substandard, and the quality to be unstable.
[0006] Therefore, there is an urgent need to develop a method for winding fiber cloth into a composite structure carbon fiber tube. Summary of the Invention

[0068] The fiber composite layers are divided into groups of two layers according to their order.
[0069] Among them, the first layer and the second layer are the first group. The two layers of fiber cloth are stacked with the first layer on the bottom and the second layer on the top. A 5mm gap is reserved at the long side with a length of 895mm. Then, the fiber combination layer is ironed flat and pressed with an iron at 55℃ to obtain the first group of fiber combination layers.
[0070] The third and fourth layers are the second group. The third layer of fiber cloth is placed at both ends of the fourth layer of fiber cloth, with a 5mm gap reserved at the long side with a length of 1805mm. Then, it is ironed flat and pressed with an iron at 55℃ to obtain the second group of fiber combination layers.
[0071] The fifth and sixth layers are the third group. The two layers of fiber cloth are stacked with the fifth layer on the bottom and the sixth layer on the top. A 5mm gap is reserved at the long side with a length of 895mm. Then, the fiber combination layer is ironed flat and pressed with an iron at 55℃ to obtain the third group of fiber combination layers.
[0072] The seventh and eighth layers are the fourth group. The two layers of fiber cloth are stacked with the seventh layer on the bottom and the eighth layer on the top. A 5mm gap is reserved at the long side with a length of 895mm. Then, the fibers are ironed flat and pressed with an iron at 55℃ to obtain the fourth group of fiber combination layers.
[0073] The ninth and tenth layers are group 5. The two layers of fiber cloth are stacked with the ninth layer on the bottom and the tenth layer on the top.

[0074] The five fiber composite layers described above are sequentially rolled onto a carbon fiber tube mold core coated with release agent. Taking the first fiber composite layer as an example, an iron is used to flatten and compact the spacing of the first fiber composite layer with the first rolling start line of the carbon fiber tube mold core. A fabric rolling machine is then used to roll the first fiber composite layer onto the carbon fiber tube mold core.

[0077] This embodiment provides a method for winding a carbon fiber tube with fiber cloth. The fiber cloth has 10 layers. Except for adjusting the 5 sets of fiber combination layers to 4 sets of fiber combination layers, the other conditions are the same as in embodiment 1.
[0078] The adjustments are as follows: The third to fifth layers are grouped into the second group. The three layers of fiber cloth are stacked with the fourth layer at the bottom and the fifth layer at the top, with the third layer located at both ends of the fourth layer. A 5mm gap is reserved on the long side with a length of 895mm. Then, the fiber combination layer is ironed flat and pressed firmly with an iron at 55℃ to obtain the second group of fiber combination layers.
[0079] The sixth to eighth layers are grouped into the third group. The three layers of fiber cloth are stacked with the sixth layer at the bottom, the seventh layer in the middle, and the eighth layer on top. A 5mm gap is reserved on the long side with a length of 895mm. Then, the cloth is ironed flat and pressed with an iron at 55℃ to obtain the third group of fiber combination layers.
[0080] The four fiber composite layers described above are sequentially rolled onto a carbon fiber tube mold core coated with release agent. Taking the first fiber composite layer as an example, an iron is used to iron and press the spacing of the first fiber composite layer and the first rolling start line of the carbon fiber tube mold core. A fabric rolling machine is then used to roll the first fiber composite layer onto the carbon fiber tube mold core. The angle between the first rolling start line of the first fiber composite layer and the second rolling start line of the second fiber composite layer is 180 degrees. The angle between the second rolling start line of the second fiber composite layer and the third rolling start line of the third fiber composite layer is 90 degrees. The angle between the third rolling start line of the third fiber composite layer and the fourth rolling start line of the fourth fiber composite layer is 180 degrees.
