Anti-torsion bearing disc in badminton shoes and production method thereof

Abstract

The invention discloses an anti-torsion bearing disc in badminton shoes and a production method thereof. The excellent properties of an amorphous alloy material including high strength, high elasticity and high toughness are ingeniously applied, the amorphous alloy material is prepared into sheets, belts or threads for improving the performance of the anti-torsion bearing disc in badminton shoes, and meanwhile, an optimized surface treatment process is adopted, so that a novel amorphous alloy / carbon fiber reinforced polymer-based composite material with comprehensively improved toughness is prepared, and the defects that a carbon fiber anti-torsion bearing disc is easy to twist and deform, easy to bend and fracture, poor in interlayer fracture toughness and insufficient in elasticity are overcome.

Description

technical field [0001] The invention relates to an anti-twist support tray, in particular to an anti-twist support tray for sneakers and a production method thereof. Background technique [0002] In the sneakers on the market, in order to reduce the weight of the sneakers and improve the stability of the shoes, one of the more effective technologies is to add a carbon fiber anti-twist support tray to the midsole of the shoes, see the attached figure 1 , commonly known as the carbon plate in sports shoes. However, the current carbon fiber anti-twist support tray has the following problems: [0003] 1. The structural design of sneakers makes the carbon plate usually thinner, resulting in insufficient elasticity and impact toughness. When the athlete takes off and lands, the impact of the ground feedback to the carbon plate cannot be well absorbed, and the arch of the foot is vulnerable to impact damage; in addition, the carbon plate is not elastic enough, and the energy feed...

AI Technical Summary

Problems solved by technology

[0003]1. The structural design of sneakers makes the carbon plate usually thin, resulting in insufficient elasticity and impact toughness

When the athlete takes off and lands, the impact of the ground feedback to the carbon plate cannot be well absorbed, and the arch of the foot is vulnerable to impact damage; in addition, the carbon plate is not elastic enough, and the energy feedback given to the athlete by rebounding after touching the ground is reduced, and the effect of shock absorption and buffering Poor, affecting the performance of athletes;

[0004]2. Since carbon fiber is an anisotropic material, the carbon plate must have the disadvantages of high brittleness and insufficient strength along a certain direction. In badminton, players will frequently use emergency When stopping, turning sharply, jumping on one or both feet, etc., the carbon plate is often subjected to torsion and bending loads. When the carbon plate is subjected to instantaneous force and deformation is too large, it is easy to cause the carbon plate to break and lead to the scrapping of the sneakers; in addition, the carbon plate The strength of the sneakers is insufficient, and the torsion resistance of the sneakers is poor. The pressure that should have been borne by the sneakers is transferred to the ankles of the athletes. When moving laterally, the probability of rollover increases, and sprains are prone to occur.

[0005]3. Carbon fiber composite material is a layered structure. The elastic modulus of carbon fiber and resin matrix is ​​very different. When repeatedly loaded, the interface between carbon fiber and resin Combined with the fact that cracks are easy to initiate and expand, resulting in low interlayer fracture toughness and poor impact toughness. When subjected to repeated impact loads, delamination damage is prone to occur, which affects the service life
