Shoe sole of road bike lock shoe and production method thereof

Abstract

The invention relates to the technical field of sports goods, and in particular relates to a shoe sole of a road bike lock shoe. The shoe sole comprises carbon fiber yarns containing epoxy resin and a PU layer, wherein multiple layers of carbon fiber yarns containing epoxy resin are respectively arranged on upper and lower surfaces of the PU layer, the three parts are compounded to form the shoe sole, and the mass of the carbon fiber yarns accounts for 30-46% of the total mass of the carbon fiber yarns and the epoxy resin. A production method of the shoe sole of the road bike lock shoe comprises the following steps: (1) producing the carbon fiber yarns containing epoxy resin, (2) molding the PU layer, (3) pre-forming the shoe sole, (4) forming the shoe sole, and (5) cutting raw edges. According to the shoe sole of the road bike lock shoe and the production method thereof, the shoe sole is simple to produce, ultra light, ultra-thin, high in strength, high in durability and stable in quality, the instantaneous impact force produced by foot trample can be effectively eliminated, the foot comfort is durable, and the sports injuries are reduced.

Description

Technical field [0001] The invention relates to the technical field of sports goods, in particular to a road bicycle lock shoe sole and a manufacturing method thereof. Background technique [0002] At present, bicycle shoes have a form of combining a layer of composite material such as carbon fiber on the sole. By virtue of the high hardness, wear resistance, corrosion resistance, and light weight of the composite material, the bicycle shoes provide more durable functions. However, the increased hardness of bicycle shoes, especially the momentary pressure of the foot stepping on the bicycle shoes from top to bottom when riding a bicycle, will cause the reaction impact force. The strong composite material layer will not eliminate the reaction force. The impact on the foot will make the foot uncomfortable, especially for a long time in the bicycle race, which consumes physical strength and makes the discomfort on the sole of the foot more noticeable, and the foot will be fatigued a...

AI Technical Summary

Problems solved by technology

However, for bicycle shoes with increased hardness, when riding a bicycle, especially the instantaneous pressure of the foot stepping on the bicycle shoes from top to bottom, the reaction impact force caused by it will not be eliminated by the composite material layer with high strength. The impact to the foot will cause discomfort to the foot, especially for a long time in a bicycle race, which consumes a lot of energy and makes the discomfort of the sole of the foot more obvious, resulting in fatigue, stiffness, and even injury to the foot
