Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
As mentioned above, the bending stiffness of the sole has a large influence on the comfort of the shoe. In current soles, a homogeneous midsole is generally made of an elastic material so that the bending stiffness of each region of the sole is substantially uniform. However, the bending stiffness of such a sole with a homogeneous midsole is limited by the material from which the midsole is made, and is usually too high or too low due to the material from which the sole is made, for example, too high may be close to 0.6Nm/Deg, or too low may be close to 0.2Nm/Deg, where Nm/Deg is newton meters per degree. Therefore, there is a need for an improved shoe sole with such a homogenous midsole, which improves the bending stiffness of the shoe sole to enhance the comfort of the shoe.
The embodiment of the application provides a sole, and as shown in fig. 1 and fig. 2, the sole is a schematic structural diagram. The sole 10 may include a

The composite carbon fiber for preparing the composite carbon fiber woven cloth and the composite carbon fiber unidirectional cloth has the performance grade of T700, and the mass ratio of the carbon fiber, the glass fiber, the resin and the auxiliary agent is as follows: 64: 0: 33: 3, wherein the auxiliary agent is curing agent diaminodiphenylmethane and thiomethyl toluene diamine.
The performance test of the shoe sole of this example, in the case of a 9 yard running shoe, the weight of the entire shoe was 177 g.
The bending rigidity test result of the sole is as follows: 0.31 Nm/Deg.
Bending stiffness tests show that the bending stiffness of the sole in this example is 0.31Nm/Deg, which is between 0.2Nm/Deg and 0.6Nm/Deg of the existing commercial shoe, and that the bending stiffness is moderate, which is adapted to the comfort requirements of the sole for the human body.
In addition, the shoe sole in this example has a dry slip coefficient of 1.07 and a wet slip coefficient of 0.78 as measured by the slip resistance test (SATRA TM144 horizontal mode). Compared with the prior commercial shoes, the dry type slip coefficient is 0.7-0.9, and the wet type slip coefficient is 0.3-0.4. The shoe sole of example 1 is superior to the conventional commercial shoe in both dry slip coefficient and wet slip coefficient, and thus has improved slip resistance.
