Problems solved by technology

At present, most of the sports shoe soles on the market are made of all-plastic injection molding, carbon fiber sheets are glued after injection molding, or foot spikes are installed on the formed soles. The joints of the foot spikes are prone to uneven force, causing the foot spikes to bend and twist even broken
Existing sports shoe soles use carbon fiber to improve the strength of the sole plate, but it cannot effectively improve the strength of the foot spikes and the connection strength between the sole plate and the foot spikes

Embodiment

[0032] The present embodiment provides a composite molding method for a carbon fiber sports shoe sole, the method comprising the following steps:

[0033] Step 1: Prepare carbon plate 10, TPU foot nail inner nail 20, TPU foot nail outer nail 30 and carbon fiber prepreg.

[0034] Among them, the carbon plate 10 can be an existing carbon plate, which is a carbon fiber composite material, which is generally formed of epoxy resin and carbon fiber. The epoxy resin can be softened in the hot pressing process and form a specific shape with the shape of the mold cavity. shape, the carbon plate is stronger than FRP after curing. The carbon plate 10 is uncured before thermoforming, where uncured includes completely uncured or incompletely cured.

[0035] The structure of the TPU foot nail inner nail 20 is as follows figure 2 As shown, the structure of the TPU foot nail outer nail 30 is as follows image 3 shown. The TPU foot nail inner nail 20 and the TPU foot nail outer nail 30 ca...

Abstract

The invention relates to a composite molding method for carbon fiber sports shoe soles, which comprises the following steps: preparing a carbon plate, TPU inner nails, TPU outer nails and carbon fiber prepreg; applying a first A layer of carbon fiber prepreg, apply a second layer of carbon fiber prepreg on the inner surface of the sleeve; fit the sleeve to the outside of the TPU foot nail, and the first layer of carbon fiber between the sleeve and the TPU inner nail The prepreg is laminated with the second layer of carbon fiber prepreg; the bottom end of the assembly is in contact with the carbon plate, so that the extension part is in contact with the carbon plate, and an integrally formed carbon fiber sports shoe sole is obtained through a hot pressing process. The method of the invention can improve the strength of the foot spikes and the connection strength between the sole plate and the foot spikes, and prevent the foot spikes from being easily bent, twisted and broken.

Description

technical field [0001] The invention relates to the technical field of sole molding methods, in particular to a composite molding method of carbon fiber sports shoe soles. Background technique [0002] The soles of sports shoes, such as football spikes, are often provided with spikes on the soleplate. For example, the spikes can be made of plastic, metal and their composite materials. Its function is to help the forefoot to increase the force, increase the speed, and prevent slipping. Let the strength of the legs fully explode. At present, most of the sports soles on the market are all-plastic injection molding, carbon fiber sheets are glued after injection molding, or foot nails are installed on the molded sole. even broken. Existing sports shoe soles use carbon fiber to improve the strength of the sole plate, but cannot effectively improve the strength of the foot nails and the connection strength between the sole plate and the foot nails.
