Sneaker sole composite forming process

Abstract

The invention discloses a sneaker sole composite forming process which comprises the steps of prepreg preparation, PA film cleaning, plasma surface treatment, fitting preforming, hot press forming and cooling demolding. A PA film and prepreg are compounded, the surface of a prepared finished product is free of holes, the abrasion resistance and the fatigue resistance are both enhanced; the PA film is subjected to plasma surface treatment before compounding, the surface roughness of the PA film is increased through the etching effect, the bonding performance of the PA film is improved, and therefore, the overall performance of the composite material is improved.

Description

technical field [0001] The invention relates to a shoe sole molding process, in particular to a sports shoe sole composite molding process. Background technique [0002] At present, most of the soles of sports shoes such as foot spikes on the market are made of plastic injection molding technology, which has good bending fatigue and wear resistance, but lacks rapid bending rebound performance or weak rebound, and the rebound of the sole Elastic speed and strength are the direct feedback of the shoe to the sole of the foot. [0003] Carbon fiber resin reinforced composites have good resilience, but in terms of bending fatigue and wear resistance, thermosetting resins are obviously inferior to thermoplastic resins, and they cannot maintain good bending fatigue under extreme conditions (such as -10°C) . Contents of the invention [0004] In order to overcome the deficiencies of the prior art, the invention provides a compound molding process for sports shoe soles with enhan...
