Problems solved by technology

Carbon fiber has the characteristics of high specific strength, tensile resistance, low bending, and low elongation. Therefore, carbon plate has the characteristics of high elastic modulus and high tensile strength, but it is not resistant to shearing and bending, and its toughness is poor. According to the force characteristics of running, both support and fast response are taken into account, which affects propulsion performance and user experience

Abstract

The invention relates to a carbon plate for running shoes, which comprises a carbon plate body, the area of the carbon plate body corresponding to each metatarsal bone is set as a metatarsal bone area, and the metatarsal bone area is sequentially set as a first metatarsal bone area, a second metatarsal bone area, a third metatarsal bone area, a fourth metatarsal bone area and a fifth metatarsal bone area. According to the invention, the carbon plate structure is designed according to different force exerting processes and stress of each area of the sole, so that the carbon plate structure has different mechanical responses at different parts, and the lower elastic modulus is designed at the weak stress part, so that the mechanical response of the sole is reduced, and the mechanical response of the sole is improved. The carbon plate at the part can quickly respond and bend and deform; a large elastic modulus is designed at a strong stress part, so that the part can provide enough support. The invention further provides a manufacturing method of the carbon plate, the carbon plate with different properties in different areas is formed through the arrangement of the carbon fiber layer and the polyimide fiber layer, and the supporting property and the quick response of the carbon plate can be considered.

Description

technical field [0001] The invention relates to a carbon plate for running shoes and a preparation method thereof, and belongs to the field of shoe accessories. Background technique [0002] There is a class of shoes on the market that add pedals to the sole for enhancing support and resilience, thereby making up for the support and resilience of the sole, and can assist the propulsion of the foot more efficiently. [0003] For example, in the Chinese utility model with the authorization announcement number CN215532060U, titled "A Novel Boosting and Shock Absorbing Sole", a carbon fiber plate is arranged between the first midsole and the second midsole. Another example is the Chinese utility model with the authorization announcement number CN213487263U, titled "A sports shoe containing a racing carbon plate", in which a racing carbon plate is arranged in the sole. The so-called "carbon plate" in the industry is a carbon fiber reinforced resin composite material, which is ma...
