Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of soles, in particular to a composite carbon plate, a sole and sports shoes. Background Art
[0002] Carbon plates have many characteristics such as light weight, high tensile strength, good shock resistance and impact resistance, and are often used in the manufacture of soles, especially sports shoe soles. Adding carbon plates in the process of manufacturing soles can enhance the support and rebound performance of the soles, and play a boosting role to assist the wearer in movement. For example, when running, wearing sports shoes with carbon plates can effectively improve the runner's running speed and efficiency.
[0003] In addition to support and rebound performance, good shoes also need to have anti-torsion function, especially for sports shoes that require high speed and agility. When wearing ordinary shoes for exercise, the center of gravity of the wearer's feet changes rapidly, and it is easy to generate rotational force between the forefoot and the heel, which in turn causes the shoes to twist, leading to side slips, sprains, ankle injuries, etc., which shows the importance of anti-torsion function. Although existing shoes with built-in carbon plates have good support and rebound performance, the anti-torsion effect still needs to be improved. Utility Model Content

[0007] Furthermore, a curing agent layer is coated on the bottom of the braided composite layer, and the first carbon fiber filaments, the magnesium wires and the unidirectional fiber layer are connected as a whole through the curing agent layer.
[0008] Furthermore, the first carbon fiber filaments and the magnesium wires are arranged and interwoven at an angle of plus or minus 45 degrees to a reference axis.

[0025] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0026] Embodiment 1: Figure 1-4 As shown, the utility model discloses a composite carbon plate, comprising a woven composite layer 1 and a unidirectional fiber layer 2, wherein the woven composite layer 1 and the unidirectional fiber layer 2 are stacked up and down and bonded to each other.
[0027] The woven composite layer 1 includes a plurality of first carbon fiber filaments 3 and a plurality of magnesium wires 4, and the first carbon fiber filaments 3 and the magnesium wires 4 are interwoven into one. In the woven composite layer 1, the first carbon fiber filaments 3 and the magnesium wires 4 are arranged and interwoven at a positive and negative 45° with a reference axis, and the structure of the woven composite layer 1 is similar to a unidirectional carbon fiber cloth. In the woven composite layer 1, the mass proportion of the first carbon fiber filaments 3 is between 60% and 90%, and the mass proportion of the magnesium wires 4 is between 10% and 40%. Optionally, the mass proportion of the first carbon fiber filaments 3 in the woven composite layer 1 is about 70%, and the mass proportion of the magnesium wires 4 in the woven composite layer 1 is about 30%.
[0028] The unidirectional fiber layer 2 includes a plurality of second carbon fiber filaments 5 extending in the same direction and arranged in parallel, and the arrangement direction thereof is set according to the use requirements. The thickness of the woven composite layer 1 and the unidirectional fiber layer 2 is selected according to the requirements, and the sum of the thicknesses of the two is preferably set between 0.5 mm and 2 mm.
[0029] The bottom of the woven composite layer 1 is coated with a curing agent layer 6, and the first carbon fiber filament 3, the magnesium wire 4 and the unidirectional fiber layer 2 are connected as a whole through the curing agent layer 6. When making a composite carbon plate, the first carbon fiber filament 3 and the magnesium wire 4 need to be interwoven to form a woven composite layer 1. As one of the cases, the magnesium wire 4 can be directly woven into the unidirectional carbon fiber cloth to form a woven composite layer 1. The woven composite layer 1 is then cut to the desired shape. After the cutting is completed, a curing agent is applied to the outside of the woven composite layer 1, especially the bottom side, to cure the first carbon fiber filament 3 and the magnesium wire 4 into one. Then, the second carbon fiber filament 5 is arranged at the bottom of the woven composite layer 1 to set the unidirectional fiber layer 2, and the curing agent is applied again to bond the woven composite layer 1 to the unidirectional fiber layer 2. After the curing agent applied twice is cured, it becomes the above-mentioned curing agent layer 6. After the woven composite layer 1 and the unidirectional fiber layer 2 are bonded, they can be hot-pressed with a mold to obtain a composite carbon plate of a specific shape.
[0030] Taking the use in the sole and full-palm setting as an example, the side view shape of the composite carbon plate after hot pressing is approximately S-shaped to fit the sole shape. The woven composite layer 1 and the unidirectional fiber layer 2 are divided into a forefoot section 7, an arch section 8 and a heel section 9 in sequence along their own length direction. A fork 10 is provided on the side of the forefoot section 7 away from the arch section 8, and the entire forefoot section 7 is divided into two parts by the fork 10. At this time, the first carbon fiber filament 3 and the magnesium wire 4 are preferably arranged with the direction from the forefoot section 7 to the heel section 9 as the reference axis direction, and the second carbon fiber filament 5 can be selected from the forefoot section 7 to extend to the heel section 9, or the direction from the forefoot section 7 to the heel section 9 can be used as the reference axis direction, and arranged at a positive and negative 45° with the reference axis.
[0031] In the composite carbon plate, the unidirectional fiber layer 2 only bends in one direction when subjected to force due to its bending characteristics, and the other direction is more stable, which greatly ensures the smoothness of the athlete's movement on uneven roads, has stronger resistance to twisting and deformation caused by movement, can provide athletes with better support and better stability, and helps reduce sports injuries caused by bad posture during exercise.
[0032] Affected by the magnesium wire 4 in the braided composite layer 1, the composite carbon plate also has many excellent properties. Compared with common metal wires such as copper wire and steel wire, the magnesium wire 4 has a higher strength-to-weight ratio. For example, compared with aluminum and steel, the density of magnesium is only 2 / 3 of aluminum and 1 / 4 of steel, but the strength of 1 kg of magnesium is equivalent to 18 kg of aluminum and 211 kg of steel, which makes the composite carbon plate braided with magnesium wire 4 have sufficient strength and better weight control. In addition to strength and weight, the magnesium wire 4 also has good plasticity and processability, and is easy to weave, cut and shape.
[0033] At the same time, magnesium has excellent shock absorption properties and can absorb vibrations. Its impact resistance is 20 times that of plastic materials. This makes the composite carbon plate have excellent impact resistance and support. When subjected to force, it can effectively resist the distortion and deformation caused by the force and provide stable support. Compared with conventional carbon plates, the rigidity and impact resistance of the composite carbon plate are obviously higher, which can be increased by more than 30%. There is a very obvious improvement in support performance. When used in the soles, it can make the shoes have excellent anti-torsion performance, which can assist sports and play a protective role at the same time.
[0034] In addition, carbon fiber has the risk of breaking when subjected to excessive impact, but magnesium wire 4 generally produces slight deformation when subjected to the same force impact, and magnesium wire 4 has good corrosion resistance, which enables the composite carbon plate woven with magnesium wire 4 to maintain structural integrity in most environments, greatly extending its service life. Moreover, magnesium metal is a relatively abundant element on the earth, and the production and acquisition costs of magnesium metal are lower than those of carbon fiber, making the composite carbon plate not only more excellent in performance, but also easier to control in terms of cost.
[0035] It can be seen that the composite carbon plate is light, strong, long-lasting, and has excellent support and anti-torsion properties. When used in footwear, it can fit the sole of the foot, provide better support and stability to the wearer, help reduce sports injuries caused by bad posture during exercise, and improve sports safety. It has excellent shock absorption performance when running, which can enhance the sports experience of the human foot throughout the gait cycle, greatly improve the efficiency of stretching, and save energy metabolism.
[0036] Embodiment 2: Figure 5 As shown, on the basis of the above-mentioned embodiment 1, the utility model further discloses a sole, including a sole body 11 and the above-mentioned composite carbon plate, which is embedded in the sole body 11. In general, the composite carbon plate can be set in the middle of the midsole, or it can be moved up or down according to design requirements to be closer to or away from the sole of the foot. The composite carbon plate can be set at the forefoot, or at the heel, or at the entire palm. Influenced by the composite carbon plate, the sole has excellent support performance, rebound performance, and anti-torsion performance, and is more resistant to distortion and deformation caused by movement.
[0037] Embodiment 3: Based on the above embodiment 2, the utility model further discloses a sports shoe, which adopts the above sole. The sports shoe has excellent support performance, rebound performance, and anti-torsion performance, and can assist the wearer in sports while protecting the wearer.
