Abstract
Description
Technical Field
[0001] The utility model relates to a carbon plate for shoes. Background Art
[0002] Carbon fiber materials are primarily used in high-tech fields such as aerospace and automotive. Carbon fiber sheets are made from these materials. They possess both high strength and stiffness, exceeding steel in strength while remaining lightweight. This makes them excellent for applications that require both high load bearing and lightweight construction. Furthermore, their low density can help reduce the overall weight of a structure.
[0003] We've experimented with using carbon fiber plates in shoe bodies. Using carbon fiber plates in shoe bodies can enhance the structural strength of the sole, reduce deformation during exercise, provide stable support for the foot, and reduce the risk of injury. However, existing carbon fiber plates used as shoe soles are prone to bending at the arch due to insufficient strength, which reduces the shoe's lifespan. Utility Model Content

[0006] polyimide fiber layer;
[0007] An arch reinforcement piece made of poly(p-phenylene terephthalamide);
[0008] Carbon fiber layer.
[0009] Preferably, the carbon fiber layer comprises 3-6 layers; at least two of the carbon fiber layers are made of carbon fiber unidirectional tapes that are symmetrically arranged in forward and reverse directions, and another carbon fiber layer is made of 90° carbon fiber unidirectional tape material.
[0010] Furthermore, the carbon fiber layer adopts 5 layers, the first carbon fiber layer is a carbon fiber layer made of carbon fiber unidirectional tape material arranged at a positive angle; the second carbon fiber layer is a carbon fiber layer made of carbon fiber unidirectional tape material arranged at a negative angle; the third carbon fiber layer is a carbon fiber layer made of 90° carbon fiber unidirectional tape material; the fourth carbon fiber layer is a carbon fiber layer made of carbon fiber unidirectional tape material arranged at a negative angle; the fifth carbon fiber layer is a carbon fiber layer made of carbon fiber unidirectional tape material arranged at a positive angle.
[0011] Furthermore, the first carbon fiber layer uses a 25° carbon fiber unidirectional tape, the second carbon fiber layer uses a -25° carbon fiber unidirectional tape, the fourth carbon fiber layer uses a -25° carbon fiber unidirectional tape, and the fifth carbon fiber layer uses a 25° carbon fiber unidirectional tape.
[0012] Another preferred embodiment is that the carbon fiber layer comprises three layers, namely a first carbon fiber layer, a second carbon fiber layer and a third carbon fiber layer;
[0013] The first carbon fiber layer is a carbon fiber layer made of 90° carbon fiber unidirectional tape material;
[0014] The second carbon fiber layer is a carbon fiber layer made of a carbon fiber unidirectional tape material arranged at a positive angle;
[0015] The third carbon fiber layer is a carbon fiber layer made of carbon fiber unidirectional tape material arranged at a reverse angle.
[0016] Furthermore, the second carbon fiber layer uses 25° carbon fiber unidirectional tape;
[0017] The third carbon fiber layer uses -25° carbon fiber unidirectional tape.
[0018] Optimization is made between structural strength and carbon plate quality, and the thickness of the carbon plate for sports shoes is between 0.8 and 2 mm.
[0019] The fineness of the polyimide fiber cloth is 1500D.
[0020] To facilitate laying, the thickness of a single carbon fiber layer is 0.1~0.2mm.
[0021] Polyimide is preferably selected, and the density of the polyimide fiber layer is 1.38g / cm3-1.43g / cm3 and the thickness is 0.1-0.2mm.
[0022] In order to enhance the structural strength of the arch of the foot, the carbon plate for sports shoes is provided with raised reinforcing ribs longitudinally at the arch of the foot.
[0023] The arch reinforcement sheet is a sheet-like structure, the shape of which does not exceed the carbon plate, but covers the arch in the longitudinal direction.
[0024] The polyimide fiber layer, the arch reinforcement sheet, and the carbon fiber layer are compounded together to form a carbon plate.
[0025] When the utility model is used, it is installed in the sole and can significantly improve the elasticity and structural strength of the sole. Other usage methods are the same as those of the carbon fiber plate in the prior art.
[0026] The beneficial effects of the present invention are as follows: 1. Providing a reinforcing plate at the arch of the foot can improve the structural strength of the carbon fiber plate at the weak part of the arch of the foot. In addition, the raised reinforcing ribs can further improve the rigidity at the arch of the foot, thereby improving the structural strength of the entire carbon plate and reducing the problem of excessive bending of the carbon plate damaging the service life. 2. The carbon fiber plate has excellent rigidity and strength, which can provide strong support for the sole of the shoe, reduce excessive twisting and deformation of the foot during exercise, and reduce the risk of injury. The strong rigidity can accurately transmit force, ensure that the force of the foot is effectively transmitted to the ground, improve the accuracy and stability of the movement, and its elastic properties can store and release energy when the foot pushes off the ground, improve the efficiency of exercise, and bring better propulsion effect to athletes.
